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 performance improvements does carbon filled PTFE tube offer over pure PTFE in chemical pump and valve applications?
A:
Carbon filling significantly improves creep resistance, compressive strength, and rigidity while lowering thermal expansion. In chemical pumps and valves, it resists cold flow deformation under sustained pressure, maintains stable sealing dimensions, and extends maintenance intervals.
Q:You offer extruded, molded, and pressed tubes. What are the differences, and how do I choose?
A:
Extruded tubes suit longer continuous lengths (500-4000 mm) at lower cost for standard diameters. Molded tubes handle large diameters (up to 1323 mm OD) and thick walls with higher density and better creep resistance. Pressed tubes cover very small diameters (0.2-25 mm OD) in rolls for precision small components. Choose based on size, pressure, and production volume.
Q:What are the specific size ranges? Can you customize non-standard dimensions?
A:
Extruded: OD 13-213 mm, ID 5.2-196 mm, length 500-4000 mm. Molded: OD 30-1323 mm, ID 10-1217 mm, length 100-300 mm. Pressed: OD 0.2-25 mm, ID 0.1-23 mm, in rolls. All sizes can be customized, and we support machining per drawings.
Q:Which chemicals can carbon filled PTFE tube resist? Is it suitable for strong acids and bases?
A:
The PTFE matrix resists most strong acids, bases, and organic solvents. Carbon filling does not compromise its chemical inertness, but strong oxidizing acids should be avoided. Provide your specific media for compatibility confirmation.
Q:Is this material easy to machine? Can you turn, drill, or slot it according to my 2D/3D drawings?
A:
Carbon filled PTFE offers excellent machinability with dimensional stability and minimal deformation. We accept PDF/CAD 2D drawings and IGES/STEP 3D models for turning, milling, drilling, tapping, and slotting - ideal for pump/valve seals, bushings, guide rings, and other precision components.
