PTFE Diaphragm
Cixi Rylion Ptfe Company manufactures PTFE Diaphragms from virgin PTFE suspension resin, a polymer known for its exceptional chemical inertness and thermal stability. The diaphragm is produced as a solid sheet that can be cut to the required dimensions and subsequently bonded to metal or rubber surfaces after one‑side etching. This construction delivers high tensile strength and low permeability, making it suitable for demanding sealing tasks. The supplier notes usage in cable gland assemblies, oil and gas pipelines and pharmaceutical equipment.
Typical PTFE diaphragm thickness ranges from 0.5 mm to 5 mm, providing a balance between flexibility and pressure resistance. Standard service temperature extends from - 200 °C to +260 °C, and the material exhibits a water absorption of less than 0.01 % by weight. In industry, the diaphragm can withstand continuous pressures up to 10 bar for the thicker grades, while thinner variants are used where space constraints dominate. Standard packaging is in protective cardboard sleeves containing 10 to 20 sheets, each labelled with thickness and size.
Buyers in the oil‑chemical, food processing and water‑treatment sectors select these diaphragms for sealing cable glands, pump housings and reactor vessels. The supplier offers third‑party inspection and can provide material test reports upon request, but does not publish MOQ or unit pricing. Importers should confirm the preferred Incoterm, such as FOB Ningbo, and arrange any required certifications for their target market. Direct communication with Cixi Rylion is required to finalise lead times and payment conditions.

Sourcing PTFE Diaphragm from Cixi Rylion Ptfe Company - China Import Guide
Before placing an order, importers should obtain a copy of the supplier’s company registration and confirm the harbor trust tier status through the relevant trade portal. Request the latest material test certificate and the PTFE sheet thickness report to ensure compliance with project specifications. Verify that the diaphragm meets the stated chemical resistance and temperature ratings by asking for the ASTM D2857 and D6694 test results.
Logistics discussions should clarify the preferred Incoterm, such as FOB Ningbo or CIF Shanghai, and the expected lead time, which the supplier does not disclose publicly. Buyers are encouraged to ask for a production schedule and estimated shipping date before confirming the purchase. Payment terms are typically negotiated on a T/T basis, with the possibility of a letter of credit for larger volumes, but the exact conditions must be agreed with Cixi Rylion.
Quality assurance can be strengthened by arranging an on‑site audit or by appointing an independent inspection agency to verify dimensions, thickness and tensile strength. Request the detailed inspection checklist that references ISO 9001 and the relevant ASTM standards. Maintaining records of the inspection report and shipping documents will aid customs clearance and downstream quality control.
