Do you provide material test reports or RoHS/REACH compliance certificates?

Yes. Each batch comes with test reports for mechanical properties, density, hardness, etc. Products comply with RoHS, REACH, and FDA (for certain filled grades).

Are these rods suitable for food contact or medical applications?

Carbon powder or carbon fiber filled grades are generally not recommended for direct food/drug contact. For food-grade applications, please choose certified virgin PTFE or a specially approved filled grade.

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 main difference between carbon powder filled and carbon fiber filled PTFE rods?

Carbon powder filling mainly improves wear resistance and creep resistance at a lower cost. Carbon fiber filling significantly enhances compressive strength, thermal conductivity, and dimensional stability, making it suitable for high-load or high-speed moving parts.

Q:Can both carbon powder and carbon fiber be mixed together as a hybrid filler?

Yes. We offer hybrid filling solutions combining carbon powder and carbon fiber, delivering balanced improvements in wear resistance, compressive strength, and thermal conductivity for demanding conditions.

Q:Can these filled PTFE rods be machined (turned, drilled, ground) to tight tolerances?

Yes. The material has good machinability, supporting turning, milling, drilling, threading, and precision grinding. We can also supply finished parts machined to your drawings.

Q:Do filled PTFE rods retain PTFE's chemical resistance?

Most chemical resistance is retained against strong acids, bases, and organic solvents. However, for extremely oxidizing media, pre-testing is recommended as carbon fillers may have a minor effect.

Q:How does the coefficient of friction compare to virgin PTFE?

Dynamic friction increases slightly (around 0.15-0.20), but remains low. Wear life is 5-10 times longer than virgin PTFE, especially ideal for oil-free lubrication applications.
