AI-Powered supplier vetting

SummaryZhenjiang Chunhuan Sealing Materials Co., Ltd. (Group) is identified as a manufacturer and trading company with its own export license, 186 employees, and more than 30 years of operating history. It produces PTFE sheets, rods, gaskets, and related plastic products, and reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials. The supplier supports extensive customization and has documented inspection, corrective-action, complaint-handling, and traceability procedures. It reports inventory capability, one-month average lead times in both peak and off-season, and 20 years of export experience. However, it does not provide 3D software design services, has no available SDK, overseas warehouse, overseas showroom, overseas agent or branch, and has not participated in offline trade shows. No valid manufacturing-capacity contract with related subcontractors is reported. Financial information is referenced for 2020–2022, but the provided slices do not disclose sufficient financial results to assess...

Supplier typeThe supplier is explicitly described as both a manufacturer and trading company with its own export license. Its stated activities include manufacturing plastic products and processing machine elements and spare parts, supporting classification as a manufacturing-oriented supplier.

CertificationsThe supplier reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials, while the sustainability-related certification is specified as ISO9001:2015. These stated certifications provide explicit evidence of certification holdings, although the slices do not verify their scope or current validity dates.

After-Sales capabilityThe supplier has clear procedures and followed records for handling customer complaints, as well as corrective and preventive actions. This directly supports an established after-sales issue-management process.

Production capacityThe supplier identifies itself as a manufacturer with 186 employees and established plastic-product production, reports in-stock capability, and states one-month average lead times in both peak and off-season. However, it also reports no valid manufacturing-capacity contract with related subcontractors, so the evidence demonstrates internal production capability but leaves outsourced-capacity controls as a limitation.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. This is direct evidence of a broad customization service range.

Product Q&A

Q:Is there any difference in acid/alkali resistance between this carbon/graphite filled PTFE sheet and virgin PTFE?

Virgin PTFE already offers excellent resistance to almost all acids and alkalis. With carbon/graphite fillers, the PTFE matrix retains its chemical inertness, so acid/alkali resistance remains largely unchanged. However, some strong oxidizing acids (e.g., concentrated nitric acid) may slightly attack the fillers. We recommend evaluating based on your specific media concentration and temperature.

Q:What are the application differences between carbon-filled and graphite-filled grades, and how do I choose?

Carbon fiber filling mainly improves compressive strength, rigidity, and creep resistance - ideal for high-load structural parts. Graphite filling enhances self-lubrication and thermal conductivity, better suited for sliding friction components like bearings and guide rails. We can recommend based on your load, speed, and temperature profile.

Q:What is the approximate Shore D hardness, and is it suitable for wear-resistant gaskets or seals?

With carbon/graphite filling, hardness typically ranges from Shore D 65 to 75, significantly higher than virgin PTFE (~55-60). Abrasion resistance and extrusion resistance are enhanced, making it ideal for high-pressure seals, slide guides, and wear liners.

Q:Is this material FDA-compliant for food or pharmaceutical applications?

The PTFE base itself complies with FDA 21 CFR 177.1550, but carbon/graphite fillers may not be FDA-approved. If food-contact is required, we can supply virgin PTFE or specially approved filled formulations - please specify your requirement beforehand.

Q:Is this material easy to machine by drilling, milling, or turning?

Yes. Carbon/graphite filled PTFE machines well without the 'gummy' behavior of virgin PTFE. Carbide tooling with coolant is recommended for smooth finishes and tight dimensions.
