How hard is this wear pad and is it prone to deformation?

Pure PTFE has a lower hardness (Shore D 50-60) and may creep under sustained high pressure. However, with glass or carbon fiber fillers, hardness increases to above Shore D 70, and creep resistance improves by more than 3 times.

Is this product FDA-compliant and can it be used in food machinery?

Pure PTFE complies with FDA 21 CFR 177.1550, but adding fillers may affect compliance. For food-grade requirements, we can use FDA-approved pure PTFE or specially certified food-grade fillers.

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:How does PTFE achieve self-lubrication and is additional oil needed?

PTFE has an extremely low friction coefficient (0.05-0.10) and forms a transfer film on the mating surface, enabling oil-free self-lubrication. Under most conditions, no extra lubricant is required, though supplemental grease can extend service life under very high loads or speeds.

Q:What vertical load and horizontal thrust can this sliding block withstand?

Load capacity depends on the material formulation. Pure PTFE has a compressive strength limit of about 10-15 MPa; with glass fiber, carbon fiber, or bronze fillers, it can reach 25-30 MPa. Please provide your load and contact area for a specific recommendation.

Q:What chemicals can this wear pad resist and is it suitable for strong acid or alkali environments?

PTFE resists almost all chemicals, making it ideal for corrosive environments such as chemical reactor guides, electroplating line supports, and pickling equipment pads.

Q:Can you customize dimensions and what is the minimum order quantity?

Yes, full customization of length, width, thickness, and hole spacing is available per your drawings. MOQ is flexible - typically 10 pieces per size, and small trial batches are also welcome.

Q:How is the sliding block mounted and do I need extra accessories?

Various mounting methods are possible: fix with screws, slide into dovetail slots, or bond with adhesives. We can machine countersunk holes, threaded holes, or dowel pin holes directly on the block according to your design, eliminating extra accessories.
