What are the typical applications for this round PTFE sheet as a corrosion-resistant disc?

Common uses include flange gaskets in chemical reactors, valve diaphragms, wear-resistant discs for pumps, separation sieve plates in food machinery, protective covers for electroplating tanks, and anti-corrosion baffles in semiconductor wet processing. Its non-stick and corrosion-proof properties also make it ideal for filter support plates and sealing rings.

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:Can this PTFE disc resist all strong acids, alkalis, and organic solvents?

Pure PTFE is chemically inert and resists almost all strong acids, strong alkalis, and common organic solvents. However, molten alkali metals and fluorine gas are exceptions. If you have a specific media list, we can verify compatibility.

Q:Can you machine center holes, mounting holes, or special cutouts on the disc?

Yes. We provide secondary operations such as drilling, milling, contour cutting, and chamfering. Just supply 2D drawings (PDF/CAD) or 3D models, and we will produce the disc to match your equipment mounting requirements perfectly.

Q:Is this PTFE disc FDA-compliant for food contact? Can it be used in pharmaceutical or food industries?

This pure PTFE product meets FDA 21 CFR 177.1550 standards, as well as ROHS and REACH requirements, with MSDS available. Therefore, it is directly suitable for corrosion-resistant discs or diaphragms in food processing, pharmaceutical equipment, and potable water systems.

Q:How does this disc perform under high-pressure or vacuum conditions?

PTFE has moderate creep resistance, but cold flow may occur under high pressure. We can recommend appropriate thickness or metal backing based on your system pressure (e.g., 1-10 MPa) and support design. For vacuum applications, a minimum thickness of 5mm with adequate support is recommended to prevent deformation.

Q:Can I customize the color or add fillers to enhance specific properties?

Yes. While the default is natural white PTFE, we can add glass fiber, carbon fiber, graphite, molybdenum disulfide, bronze powder, etc., to improve rigidity, wear resistance, or thermal conductivity. Note that filled grades will not be FDA-compliant. Please clarify your service conditions, and we will propose the appropriate formulation.
