Product Description

1. Expanded PTFE sheet is an extremely compressible material manufactured from 100% virgin PTFE. It is a food approved product and has excellent resistance to a wide range of chemicals, making it a popular sealing material in the food, drink and pharmaceutical industries.

The material is commonly converted into gaskets and is a popular option with delicate, worn and damaged flanges as it has a low bolt load requirement. It can also withstand compressive loads of over 40,000 psi without losing any sealing capability.

1. Key Features

Temperature: -240°C to +270 °C (briefly up to +315°C).
Very soft, extremely compressible and has excellent resistance to many chemicals.
It is also unaffected by ozone, UV and corona and does not become brittle with age.
