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 media can expanded PTFE sheet be used to seal?
A:
It is suitable for strong acids, strong alkalis, solvents, hydrocarbons, refrigerants, steam, oxygen, and food-grade media. Due to its chemical inertness, it resists almost all industrial chemicals (except molten alkali metals and high-temperature fluorine gas).
Q:Is this material suitable for food or pharmaceutical applications?
A:
Yes. Expanded PTFE sheet is typically made of pure PTFE without binders or fillers. It complies with FDA 21 CFR 177.1550 and also meets USP Class VI and EU 1935/2004 standards, making it suitable for food processing, pharmaceutical, and drinking water systems.
Q:Is this gasket sheet prone to creep or cold flow?
A:
The micro-fibrous structure of expanded PTFE significantly reduces creep and cold flow tendencies. It exhibits much lower stress relaxation compared to standard PTFE, with minimal thickness loss over long-term service, making it ideal for applications requiring sustained bolt preload.
Q:Can the thickness and size of expanded PTFE sheet be customized?
A:
Yes. Common thicknesses include 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 3.0 mm, etc. It is available in rolls or sheets. We can also cut to gaskets per your drawing or die-cut any shape.
Q:Does installing an expanded PTFE gasket require very high bolt preload?
A:
No. Expanded PTFE sheet offers excellent compressibility and recovery. A tight seal can be achieved with relatively low bolt load, making it especially suitable for brittle flanges (e.g., FRP, plastic, ceramic) or low-pressure, large-diameter equipment.
