| Accounting Policies [Abstract] | |
| Basis of Presentation | We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Prior to October 30, 2025 (“the Spin-off date”), the accompanying unaudited combined financial statements have been derived from Honeywell and presented on a standalone basis as if the Company’s operations had been conducted independently. The accompanying financial statements for periods prior to the Spin-off date include all revenues and costs directly attributable to the Solstice Advanced Materials business and an allocation of expenses related to certain Honeywell corporate functions. These expenses were allocated to the Solstice business based on a proportion of net sales. Solstice and Honeywell considered these allocations to be a reasonable reflection of the utilization of services or the benefits received. However, the allocations may not be indicative of the actual expense that would have been incurred had Solstice operated as an independent, standalone entity, nor are they indicative of future expenses of Solstice. Honeywell used a centralized approach to cash management and financing of its operations. Accordingly, for periods prior to the Spin-off, a substantial portion of the Business’s cash accounts were regularly cleared to the former Parent at Honeywell’s discretion and Honeywell funded the Business’s operating and investing activities as needed. Honeywell’s long-term debt and related interest expense were not attributed to Solstice for any of the periods presented as the Business was not the legal obligor of such borrowings and Honeywell’s borrowings were not directly attributable to the Business. All significant intercompany transactions, including transfer of cash, between Solstice and Honeywell prior to the Spin-off were included within Net transfers to Parent on the statements of cash flows and the statements of equity through the pre-Spin-off periods. After the Spin-off date, the Company’s financial statements are consolidated financial statements based on our reported results as a standalone company. All significant transactions between Solstice entities were eliminated. The accompanying financial statements for all periods presented, including the historical results of the Company prior to the Spin-off, are now referred to as “Consolidated Financial Statements.” Certain items have been recast to conform to current-period presentation. We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the SEC applicable to interim financial statements. Accordingly, certain note disclosures have been condensed. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements, corresponding notes, and significant accounting policies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 Annual Report on Form 10-K”). Within the financial statements and tables presented, certain columns and rows may not add due to the use of rounded numbers for presentation and disclosure purposes. Percentages presented are calculated from the underlying whole-dollar amounts. The Company reports its quarterly financial information using a calendar convention; the first, second, and third quarters are consistently reported as ended on March 31, June 30, and September 30, respectively. It is the Company’s practice to establish actual quarterly closing dates using a predetermined fiscal calendar, which requires the Company’s businesses to close their books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on the Company’s business processes. The effects of this practice are generally not significant to reported results for any quarter and only exist within a reporting year. In the event differences in actual closing dates are material to year-over-year comparisons of quarterly or year-to-date results, the Company will provide appropriate disclosures. The Company’s actual closing dates for the six months ended June 30, 2026, and 2025 were June 27, 2026, and June 28, 2025, respectively.

| Use of Estimates | Use of Estimates The Company prepares its Consolidated Financial Statements in conformity with GAAP. In doing so, the Company is required to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. The Company bases these estimates on historical experience and on various other assumptions that the Company believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The Company’s actual results may differ materially from these estimates. Significant estimates inherent in the preparation of these Consolidated Financial Statements include, but are not limited to, accounting for allocation of expenses related to certain Honeywell corporate functions (prior to the Spin-off), evaluation of allowance for doubtful accounts, reserve for inventory obsolescence, goodwill and other intangible assets for impairment, environmental liabilities, asset retirement obligations (“ARO”), commitments and contingencies, pension liabilities and expenses and income taxes.

| Transaction-related costs | Transaction-related costs The Company classifies certain expenses related to the Spin-off, as well as related to potential or completed acquisitions and divestitures (if any) as Transaction-related costs in the Consolidated Statements of Operations. The Transaction-related costs include one-time and non-recurring expenses associated with the separation and stand-up of functions required to operate as a standalone public entity. These non-recurring costs primarily relate to legal, accounting, consulting and other professional service fees, system implementation costs, business and facilities separation, development of our brand and other matters.

| Supply Chain Financing | Supply Chain Financing Amounts outstanding related to supply chain financing programs are included in Accounts payable in the Consolidated Balance Sheets.

| Recent Accounting Pronouncements | Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's Consolidated Financial Statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which improves the navigability of required interim disclosures, clarifies when that guidance is applicable, and introduces a new principle requiring companies to disclose events since the end of the last annual reporting period that have a material impact on the company. The ASU can be applied prospectively or retrospectively for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract, which excludes certain contracts from the scope of derivative accounting and clarifies the guidance on noncash consideration from a customer for the transfer of goods or services. The ASU can be applied prospectively for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with modified retrospective application and early adoption permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which amends the accounting for costs related to internal-use software. The update removes all references to project stages and clarifies the two conditions needed to be met to begin capitalizing costs under ASC 350-40. The ASU can be applied prospectively, retrospectively, or via a modified prospective transition approach for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income— Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires companies to disclose additional information about the types of expenses in commonly presented expense captions. The new standard requires tabular disclosure of specified natural expenses in certain expense captions, a qualitative description of amounts that are not separately disaggregated, and disclosure of the Company's definition and total amount of selling expenses. The ASU should be applied prospectively for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with retrospective application and early adoption permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements.

| Contract Balances and Performance Obligations | Contract Balances The Company tracks progress on satisfying performance obligations under contracts with customers and records the related billings and cash collections on the Consolidated Balance Sheets in Accounts receivable – net. Unbilled receivables (contract assets) arise when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. Deferred revenue (contract liabilities) arise when customers remit contractual cash payments in advance of the Company satisfying performance obligations under contractual arrangements. Contract liabilities are derecognized when performance obligations are satisfied. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. The effect of a contract modification on the transaction price and the Company’s measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at stand-alone selling price, they are accounted for as a new contract and performance obligations, which are recognized prospectively. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account. The Company allocates a contract’s transaction price to each distinct performance obligation and recognizes revenue when, or as, the performance obligation is satisfied. When contracts with customers require highly complex integration or manufacturing services not separately identifiable from other promises in the contracts and, therefore, not distinct, then the entire contract is accounted for as a single performance obligation. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on the estimated relative stand-alone selling price of each distinct good or service in the contract. For product sales, each product sold to a customer typically represents a distinct performance obligation. In such cases, the observable stand-alone sales are used to determine the stand-alone selling price. Performance obligations satisfied at a point in time are supported by contracts with customers, providing a framework for the nature of the distinct goods, services or bundle of goods and services. The timing of satisfying the performance obligation is typically indicated by the terms of the contract. Substantially all of the Company’s revenue relates to transfer of control of products or delivery of conversion services at a point in time. The Company’s contracts generally do not contain a significant financing component, as the period between when the Company transfers control of the product or service to the customer and when the customer pays for that product or service is one year or less.
