Changzhou Sunchem New Material is presented as a source-reviewed supplier profile centered on SK-series polyimide molding powders, with company-published capability separated from buyer-side verification requirements.
Changzhou Sunchem New Material Co., Ltd. (SUNCHEM) is a high-performance polymer-material supplier in Xinbei District, Changzhou, Jiangsu. Both the official website and China Composites Expo date the business to 2009 and describe R&D and production of polyimide materials, high-performance resins, molding powders, plastics and finished products. The published range covers polyimide molding powders, ultrafine and soluble ultrafine powders, bismaleimide resin, high-temperature epoxy resin, polyamic-acid solutions, and materials or products for films, coatings, adhesives, profiles, parts and composites. Company-published application fields include aerospace, naval and defence equipment, electronic information and integrated circuits. The expo and official website both use Changzhou Sunchem New Material Co., Ltd.; the exact Chinese legal name, telephone, domain email and product scope align, so this page consolidates them into one supplier identity. Product-performance, application and technical-capability statements are company- or organizer-published and should be validated for the quoted grade, batch and end use.

This procurement profile is built for formulators, processors and procurement teams comparing chemistry, processing window, cured performance and regulatory documentation. It organizes Changzhou Sunchem New Material Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Changzhou Sunchem New Material SK-series polyimide molding powders.” The objective is to help a buyer decide whether to open a controlled RFQ, not to turn a broad company catalog into an unsupported approval.
Changzhou Sunchem New Material Co., Ltd. currently lists 8 product or service groups and 6 manufacturing or support capabilities in this reviewed record. The public scope indicates what to investigate, while the buyer remains responsible for drawings, design calculations, standards, current certificates, sample approval and order-specific commercial confirmation. Claims below are attributed to the attached source set unless GetFRP explicitly labels them as qualification guidance.
Sunchem's official product table lists 15 SK grades. Polyimide molding powders include SK-010, SK-0110, SK-0120 and SK-0130, with company-published uses covering engine parts, bearings and bushings, gaskets, wear strips, guide rings, insulation parts, seals and piston rings. SK-0131/0132 polyimide ultrafine powders and SK-0170/0180/0190 soluble ultrafine powders target interlaminar toughening of high-temperature epoxy- or bismaleimide-matrix carbon-fiber composites; selected soluble grades are also listed for gas-separation membranes. SK-0310 is a soluble bismaleimide resin, SK-0430 is a high-temperature epoxy for pultruded tubes, rods and composite products, and SK-0910 through SK-0940 polyamic-acid solutions cover films, fibres, coatings, enamelled wire, adhesives and composite-matrix applications. The official quality page shows atomic-absorption spectroscopy, heat-deflection/Vicat, friction and wear, high/low-temperature mechanical, infrared, impact and melt-flow instruments, but equipment photographs do not establish accredited laboratory capability. A powder or resin RFQ should define chemical structure and grade, physical form, particle size and distribution, purity, volatiles, moisture, ash, glass-transition or heat-deflection temperature, melt or solubility behaviour, solvent and solids, viscosity, gel time, storage, shelf life, packaging, batch CoA and change control. For carbon-composite toughening, pultrusion, film or electronic use, also specify compatible resin and fibre, addition level, mixing and dispersion, cure cycle, interlaminar toughness, thermal, dielectric and flame performance, ionic contamination, outgassing and destination regulation. Supplier-published temperature or application statements must not be extrapolated to the buyer's finished product. Sample and production approval should include current TDS/SDS, original test methods and curves, boundary samples, batch traceability, third-party validation, MOQ, lead time, capacity allocation, export packaging, and intellectual-property or controlled-use compliance. The official contact page gives the general location Honglou Road, while public registration data lists No. 228 Yunnan West Road, Benniu. Confirm registered, R&D, production, warehouse, invoicing, payment and dispatch sites in writing before an audit, contract, payment or shipment.
Evaluate Changzhou Sunchem New Material Co., Ltd. as a potential composite resin supplier for SK-series polyimide molding powders, verify the public evidence and prepare a comparable RFQ.
Changzhou Sunchem New Material Co., Ltd. includes this product in its published supply scope. Treat that listing as a starting point: request the current datasheet or drawing, material and construction, available grades or dimensions, guaranteed properties, production site, quotation revision and evidence that represents the exact item offered.
For SK-series polyimide ultrafine powders, buyers should convert the catalog description into an acceptance specification. Confirm standard and custom options, raw-material system, critical tolerances, surface or finish, test basis, sample route, MOQ, lead time and packing. Any alternative proposed by Changzhou Sunchem New Material Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.
This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Changzhou Sunchem New Material Co., Ltd. for the grade or model designation, manufacturing route, current technical file, production and test location, batch traceability and the limits that apply to published performance values.
Changzhou Sunchem New Material Co., Ltd. publishes High-performance polymer and resin R&D as part of its capability scope. Buyers should ask which site and equipment perform the work, the practical size or material limits, the normal control records and whether the proposed order uses the same route. Subcontracted stages should be visible in the quality plan.
The relevance of Polyimide polymerization and powder or solution preparation depends on the requested product and acceptance criteria. During qualification, request a process flow, critical control points, inspection or test method, operator or equipment qualification where applicable, nonconformance handling and a recent example that represents the offered production route.
For sourcing purposes, Molding-powder, ultrafine-powder and pellet production is a capability signal rather than independent verification. Confirm capacity, tooling or fixture availability, setup and changeover assumptions, lot definition, sample approval and traceability. The quotation should identify any limitation that could affect geometry, performance, appearance or delivery.
Buyers evaluating High-temperature epoxy and bismaleimide resin formulation should connect the process claim to evidence: an equipment list, controlled procedure, representative report, production photograph or witnessed sample may each answer a different risk. Changzhou Sunchem New Material Co., Ltd. should also explain how the result is checked before release and recorded for the shipment.
These are sourcing contexts suggested by the published product scope, not confirmed project references. Validate the exact application, design basis and evidence in the RFQ.
Changzhou Sunchem New Material Co., Ltd.'s chemistry portfolio can be evaluated for the named composite process only after the processing window and cured-property basis are aligned. Request current data sheets, grade and site identity, viscosity or mix control, cure and exotherm, storage, batch certificate fields and test evidence based on the intended reinforcement and construction.
Changzhou Sunchem New Material Co., Ltd.'s listed machinery can enter a line comparison when the buyer supplies a written product and process requirement. The proposal should define the complete line boundary, controls, utilities, safety, throughput, acceptance test, installation, training, spares, documentation and the responsibility for proving product quality with representative material.
Changzhou Sunchem New Material Co., Ltd.'s tooling scope can be considered for new or replacement production tools. Buyers should release controlled product and interface drawings, material and process assumptions, critical datums, tool material and treatment, heating or flow requirements, trial conditions, acceptance measurements, ownership, maintenance and protected transport.
Changzhou Sunchem New Material Co., Ltd.'s source record currently includes Official Sunchem Company Profile, Official Sunchem Product and Grade Table, Official Sunchem Quality Page, Official Sunchem Contact Page. These links let a buyer distinguish company-published information from GetFRP's own qualification guidance and return to the original context when a claim changes.
The profile lists 1 company-published certification or test references. A listing is not the same as validation: request the complete current document, issuer, legal holder, production site, product and grade scope, standard edition, report specimen and validity date before citing it in a project or purchase order.
GetFRP last recorded a public-source review date of 2026-08-13. Public websites and catalogs can change after review, so commercial decisions should use newly downloaded files and direct supplier confirmation. GetFRP's public or claimed status describes profile ownership and identity controls; it does not certify every product statement or predict order performance.
