Soft Flexible Etched PTFE Sheet

Soft flexible etched PTFE sheet is a product with many tiny holes. They are from a stretch-molding and puffing process.

Its relative density has fallen due to the many micropores. The relative density of PTFE products is about 2.15. Expanded PTFE products have a relative density of less than 0.1, meaning 96% porosity. The many micropores in expanded PTFE give it new functions. It retains its excellent properties, such as separation, softness, elasticity, and sealing.

Soft Flexible Etched PTFE Sheet

Features:

– Soft and elastic; excellent sealing effect.

– Chemical resistance

– Strong acid and alkali resistance.

– Anti-aging

– Excellent tensile strength

Fibrillation significantly reduces cold flow creep.

– Suitable for sealing surfaces with unevenness.

Good Seals:

An expanded PTFE gasket is suitable for sealing rough surfaces. It can conform to the molding without increasing pressure. This produces a good seal on rough or damaged flanges.

It only reacts with fusible alkali metals, free fluorine, and a few rare chemicals. You can use it for all sealing jobs within a 315℃ limit. This will significantly reduce the variety and quantity of seals.

Easy to cut and install:

The many micropores have caused a large reduction in their relative density. Mechanical stamping or hand cutting of gaskets into any shape makes your job easier.
