Teflon and Gylon Sheet
Description:
Teflon is the most widely used plastic for industrial sealing. The only products that chemically attack Teflon is liquid alkaline metals and free fluorine.
Teflon gaskets are used in services where it is necessary to have a high chemical resistance.
Teflon also has excellent properties for electrical insulation, anti-stick, impact resistance and low friction coefficient.
- Good Temperature
- Excellent electrical Insulation
- Excellent Anti-Stick
Major characteristics include:
TF 1500 Virgin PTFE Sheet
Description and Applications
Style TF1500 PTFE (polytetrafluoroethylene) is a high molecular weight polymer and one of the most versatile plastics known to man. Style 1500 virgin PTFE sheet can handle virtually all chemicals in the 0-14 pH range with the exception of molten alkali metals and elemental fluorine. It is suitable for service at temperatures from the cryogenic range up to 500°F.
This style is particularly recommended for applications in the food and beverage industry where high purity materials are required. It is also used where contamination or discoloration of flow media cannot be tolerated.

Hot Compression Test
This performance test measures the behavior of rPTFE and PTFE gaskets in a real world environment. The chart below shows a comparison between conventionally skived PTFE and Tealon. The gaskets we tested simulated a real world application including thermo-cycling. The skived PTFE gasket showed a very high leak rate, losing 60% of its initial pressure by the end of the test.
The Tealon® gasket lost only 6% of its initial pressure by the end of the test and showed a leak 10 times less than that of the skived PTFE gasket. The pictures below, show the gaskets after the test and exhibit the dimensional stability of Tealon as compared to the noticeable creep of the skived PTFE gasket.

24SH ePTFE Gasket Sheet 100% Expanded PTFE Sheet
Description and Applications
TEADIT® 24SH is a large gasket sheet produced from 100% pure, multi-directionally expanded PTFE.
Universally employable 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.
The excellent malleability of TEADIT® 24SH makes repairing small damage and/or irregularities of the sealing area (flange surface) unnecessary.
Gaskets cut from TEADIT® 24SH are dimensionally stable, i. e. they do not get wider when compressed. This allows narrow flange faces to be sealed safely.
TEADIT® 24SH is quick and simple to install. The used gasket can be removed easily and without residue.
