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 a PTFE single-sided sodium etched sheet and its main application?
A:
It is a pure PTFE sheet with one side chemically treated by sodium etching to make the originally non-stick surface bondable with epoxy, acrylic, rubber adhesives, etc. It is mainly used for linings, gaskets, guide rails, seals, and composite parts with metal or rubber.
Q:How to quickly tell the etched side from the untreated side?
A:
The etched side appears dark brown, tan, or dark grey with a slightly rough feel. The untreated side keeps PTFE's natural milky white, smooth, and highly hydrophobic look. A water drop test: water spreads on the etched side but beads up and rolls off the untreated side.
Q:How long does the adhesion property last after etching? Is there a shelf life?
A:
The etching effect gradually decays over time. It is recommended to complete bonding or lamination within 6 months after treatment. Store the sheet covered with PE film, away from direct sunlight, high heat, humidity, or oil contamination. Sheets older than 6 months can be re-evaluated for surface reactivation.
Q:Which adhesives work best on single-sided etched PTFE?
A:
Recommended adhesives include epoxy resin (bisphenol-A type), cyanoacrylate instant glue, polyurethane, and modified acrylic structural adhesive. Always consult your adhesive supplier for compatibility with etched PTFE and perform a small-area test before full application.
Q:Is any extra surface preparation needed before bonding?
A:
Generally, just gently remove loose dust using a clean non-woven cloth or soft brush. Avoid vigorous wiping with organic solvents like alcohol or acetone, as they may damage the etched layer. If the surface is visibly dirty, wash mildly with a neutral detergent solution and dry thoroughly.
