Company Profile

ePTFE Sealing Sheet – Flexible White Gasket Material, 0.5-10mm Thickness

ePTFE (Expanded Polytetrafluoroethylene)

Expanded Polytetrafluoroethylene (ePTFE) is a highly versatile, porous form of polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene, which is chemically inert and widely known under brand names like Teflon. Unlike traditional PTFE, ePTFE is produced through a specialized expansion process that involves stretching PTFE under controlled conditions to create a microporous, fibrous structure. This 3D network of interconnected nodes and fibrils gives ePTFE unique physical and mechanical properties, making it distinct from its solid PTFE counterpart.

Main Technical Indicators

Compressibility: 45±5%
Rebound rate: ≥10%
Sealing leakage rate: ≤1.0×10⁻³ cm³/s
Density: 0.7–0.9 g/cm³

Product Specifications

Available in different sizes, including:

Standard Sizes: 1500×1500mm, 1500×4500mm, 1800×1800mm, 1800×5400mm
Thickness Range: 0.5mm-10mm

Advantages

✅ Excellent chemical resistance
✅ Soft, flexible, and requires light clamping force to seal
✅ Easy to cut, can be handled with normal scissors or knives
✅ High-intensity, fibrous, 3D structure that significantly reduces cold flow and creep
