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:What is the performance difference between this compression molded sintered PTFE round plate and extruded PTFE sheets?

Compression molding provides lower internal stress, better isotropy, and superior thickness uniformity compared to extruded sheets. It is especially suitable for gaskets, linings, and insulating parts that require high flatness and greater thickness, reducing warpage and deformation risks.

Q:Can it withstand all strong acids, alkalis, and organic solvents? Are there any exceptions?

PTFE is chemically inert to almost all common chemicals, including concentrated sulfuric acid, hydrochloric acid, nitric acid, aqua regia, sodium hydroxide, and most organic solvents. The only exceptions are molten alkali metals, fluorine gas at high temperature, and certain super-strong oxidizers (e.g., chlorine trifluoride), which will attack PTFE.

Q:Can I drill, turn, or mill the plate? What precautions should I take?

Yes, PTFE is readily machinable. However, because it is soft and has poor thermal conductivity, we recommend using sharp tools, appropriate cooling, and light feed rates to avoid heat-induced deformation or burrs. We can also offer pre-machining services per your drawings.

Q:Does this product have FDA food-contact certification and comply with ROHS and REACH?

Yes. This virgin PTFE plate meets FDA 21 CFR 177.1550 for food contact, as well as ROHS and REACH directives. Declarations of conformity and MSDS documentation are available for food, pharmaceutical, and export applications.
