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 this PTFE rod made from 'virgin' material, or does it contain recycled or filled content?

It is 100% virgin PTFE with no recycled material, regrind, or fillers. Virgin resin ensures the highest chemical purity, low extractables, and stable physical properties, making it ideal for food and pharmaceutical applications where cleanliness is critical.

Q:What does the FDA certification specifically mean? Can I use it in direct food contact parts?

The material complies with FDA regulation 21 CFR 177.1550 for polytetrafluoroethylene used in food contact. It can be used in food processing equipment as seals, guides, scrapers, or conveying components that directly contact food (including fatty foods), provided that the end-use conditions (temperature, time) remain within regulatory limits.

Q:What are the typical mechanical properties, such as tensile strength and hardness?

Typical tensile strength is 25-35 MPa (depending on processing), elongation at break approximately 250-400%, and Shore D hardness in the range of 55-65. While load-bearing capacity is lower than filled PTFE, it performs excellently in low-load sealing and sliding applications.

Q:Is this PTFE rod easy to turn, drill, tap, or mill?

PTFE has excellent machinability and can be processed with standard metalworking tools for turning, drilling, milling, and tapping. We recommend sharp tools, low feed rates, and proper cooling to achieve a smooth surface and avoid burrs or deformation.

Q:What are the main recommended industries and applications?

It is primarily used in food and beverage, pharmaceutical, biotechnology, cosmetics, and fine chemical industries. Typical components include conveyor guides, scraper blades for mixing vessels, sealing gaskets, pipe connectors, and other non-load-bearing structural parts requiring corrosion resistance and easy cleaning.
