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 fillers are available for this filled modified molded PTFE tube, and how do they improve mechanical properties?
A:
We offer carbon fiber, glass fiber, graphite, molybdenum disulfide (MoS2), bronze powder, carbon powder, and combinations. Carbon fiber and glass fiber significantly boost compressive strength and rigidity (elastic modulus). Graphite and MoS2 reduce friction and enhance self-lubrication. Bronze improves thermal conductivity and creep resistance. Carbon-based fillers provide electrical conductivity/anti-static properties. Choose the optimum formulation based on your working conditions.
Q:What specific performance advantages does molded PTFE tubing have over extruded tubing?
A:
Molding allows higher filler loading (up to 40%) with more uniform distribution, yielding higher density and extremely low porosity. Molded tubes offer superior compressive strength, rigidity, and dimensional stability compared to extruded ones, especially for high-pressure, large-diameter, or tight-tolerance applications.
Q:How many times is the wear resistance improved? Which friction conditions is it suitable for?
A:
Wear resistance (e.g., abrasive wheel tests) can be 3-5 times higher. This tubing is ideal for continuous friction scenarios such as abrasive-laden fluid transport, reciprocating guide sleeves, and rotating shaft protective sleeves, effectively reducing debris generation and prolonging equipment life.
Q:Do fillers affect PTFE's chemical resistance? Which media can it resist?
A:
The PTFE matrix retains excellent chemical resistance, resisting almost all strong acids, strong alkalis, and organic solvents. Most fillers (glass, graphite, MoS2) are also corrosion-resistant; bronze and carbon require caution in strong oxidizing acids, but are fully suitable for oils, water, salt solutions, and mild acids/bases. We recommend a safe formulation based on your media.
Q:Can dimensions and lengths be customized? Is secondary machining per drawings supported?
A:
Absolutely. Inner diameters from 10mm to 500mm, with wall thickness and length to order. We accept 2D drawings (PDF/CAD) and 3D models (IGES/STEP), and can perform turning, milling, drilling, slotting, threading, and other secondary operations to meet complex installation needs.
