Product Description
This year we moved our factory to a new big plant. And recently we produce ePTFE sheet by ourselves in our new workshop. The ePTFE sheet we produced has the same quality compared with Gore but with much better price!!! And we can brand your own marks on the sheet!

Now we are having a big sell about expanded PTFE sheet,the price is very very good. Welcome to your enquiry!
Expanded PTFE Sheet for Gasket Material
Expanded PTFE Sheet for Gasket Material



P300 is a Universal sheet gasket material for most services. Seals rough and irregular surfaces.  Made from biaxial oriented expanded PTFE sheeting that is laminated to the required thickness.  Seals of up to 3000+psi can be achieved depending on the flange type & design and type of media being sealed.  Chemically resistant over the Q-14 pH range.  Specific gravity: 4 to 6.  Suitable for temperatures to 600F.
CONSTRUCTION
Our P300 gasket sheet 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.P300 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 / SERVICE
Our P300 is an all 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, Our P300E not only resists chemical attack, but it will not contaminate or discolor end products. These industries currently use expanded PTFE sheet:

 Distilleries

 Petrochemical

 Food and Beverage

 Pharmaceutical

 General Chemical

 Power generation

 Iron and Steel Manufacturing

 Pulp and paper

 Marine
