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:Why choose graphite-filled PTFE tube over virgin PTFE or glass-filled alternatives?

Graphite filler significantly improves thermal conductivity, creep resistance, and dimensional stability, reducing cold-flow deformation. It also provides self-lubrication, making it ideal for dynamic seals and precision machining where heat dissipation or low friction is required.

Q:Does graphite filler affect the chemical resistance of PTFE?

Graphite is chemically inert, so the tube still resists most acids, alkalis, solvents, and oils. However, strong oxidizing agents or high-temperature fluor gas may not be suitable - please provide your specific media for our assessment.

Q:Does the tube meet FDA food-contact requirements? Can you provide ROHS and REACH declarations?

The graphite-filled version is generally not recommended for direct food or drug contact due to possible filler migration. For food-grade needs, we offer a virgin PTFE option. However, this product comes with ROHS and REACH conformity declarations, plus MSDS, for industrial equipment export and environmental compliance.

Q:What size ranges are available for customization? What is the maximum length?

Inner diameter can range from 6mm up to 500mm, wall thickness and length are made to order, with standard length up to 2000mm. Short cut-pieces or collars can also be supplied. For extra-large sizes, please consult our engineering team.

Q:Can you machine custom shapes or flanged tubes from my 3D drawings? Do you support sample prototyping?

Yes. We accept 2D/3D drawings in PDF, CAD, IGES, and STEP formats, and can produce complex profiles with grooves, steps, or flange ends. Small-batch sample orders are also welcomed for assembly validation and performance testing.
