Product Description

Expanded PTFE Gasket Sheet Material is manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The resulting product exhibits characteristics significantly different than conventional PTFE sheet. This style is much softer and more flexible than regular PTFE sheet and thus conforms easily to irregular and rough surfaces. In addition, the material is easier to compress and minimizes creep and cold flow.

Product Detail

Expanded PTFE Gasket Sheet Material is manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and 

highly fibrillated microstructure with equal tensile strength in all directions. The resulting product exhibits characteristics significantly different than 

conventional PTFE sheet. This style is much softer and more flexible than regular PTFE sheet and thus conforms easily to irregular and rough 

surfaces. In addition, the material is easier to compress and minimizes creep and cold flow.


Application:

Expanded PTFE Gasket Sheet Material complies to FDA regulations for food contact and EU 1935/2004.

Expanded PTFE Gasket Sheet Material is an purpose gasket sheet that can replace all other types of PTFE sheet. It will seal all aggressive chemicals 

over the entire 0-14 pH range, except for molten alkali metals and elemental fluorine. Made from 100% virgin PTFE, it not only resists chemical attack, 

but it will not contaminate or discolor end products.

industries usage areas:

Distillers, Petrochemical , Food and Beverage, Pharmaceutical, General Chemical, Power Generation, Iron and Steel manufacturing, Pulp and Paper, 

Marine.


Advantages:

Expanded PTFE gasket sheet for all applications. It is suitable for all types of flanges, nearly all media, a wide temperature range and for applications 

with the toughest demands on purity. It is inherently clean and non-toxic. Gaskets of multi-directionally expanded PTFE have exceptional mechanical 

strength which allows operation with minimal creep at elevated temperatures. Gaskets cut from Expanded PTFE Gasket Sheet Material are  stable. 

they do not get wider when compressed. This allows narrow flange face to be sealed safely
