Expanded PTFE Sheet

Expanded PTFE sheet from Cixi Rylion Ptfe Company is made from 100% virgin polytetrafluoroethylene using a proprietary expansion process that creates a fibrillated microstructure with uniform tensile strength in all directions. Unlike conventional PTFE sheet, this material is significantly softer and more flexible, allowing it to conform to uneven, rough, or warped surfaces without cracking or delaminating. The product retains the chemical inertness and thermal stability of PTFE while gaining elastomeric properties that enhance sealing performance.

The material typically has a density between 0.9 and 1.1 g/cm³ and a thickness range of 0.1 mm to 5.0 mm, with standard widths up to 1200 mm. It is available in natural white or dyed variants, though colorants must be PTFE-compatible to avoid compromising performance. The expanded structure gives it a porous, fibrous texture that improves compressibility and recovery under load, making it suitable for dynamic sealing applications where traditional PTFE would fail. Typical elongation at break exceeds 200%, and it maintains integrity from -200°C to +260°C.

This sheet is commonly used in gaskets, valve seats, pipe seals, and flange linings across chemical processing, pharmaceutical, food processing, and semiconductor industries. Buyers include OEM manufacturers, maintenance contractors, and industrial distributors sourcing for high-purity or corrosive environments. Packaging is typically in rolls or flat sheets, protected by polyethylene film and shipped in cardboard cartons. Minimum order quantities are negotiable but often start at 5 square meters for standard thicknesses. Lead times vary by volume and customization.

Cixi Rylion Ptfe Company operates from Kandun Block, Zhejiang, China, and specializes in manufacturing expanded PTFE products using proprietary expansion techniques. The company's trust tier is listed as harbor, indicating basic verification of business registration and contact details. There is no public data on years in operation, workforce size, or export history. The listing confirms production capability but does not state certifications, client names, or quality management systems.

The supplier does not provide details on laboratory testing, R&D capacity, or customer support structure. Response rate and average response time are not tracked, suggesting limited engagement with buyer inquiries. No claims are made about ISO certification, FDA compliance, or environmental standards. Buyers should treat this as a manufacturer of raw PTFE sheet without verified quality assurances unless confirmed directly.
