TF1500:  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. 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.

TF1525:  Style TF1525 PTFE (polytetrafluoroethylene) is filled with 25% glass fibers by weight. The filled material significantly reduces cold flow and creep and increases wear resistance compared to unfilled PTFE sheet. It can handle a very broad range of chemicals.

TF1560:  TF1560 is a structured PTFE manufactured by a unique process that provides a high level of fibrillation to overcome the creep relaxation and cold flow problems associated with normal (skived or molded) PTFE sheets. This style is produced from virgin PTFE resin without fillers or additives. Due to the product’s low permeability it is recommended for application where media permeation through the gasket is not acceptable.

TF1570:  Tealon TF1570 is filled with glass microspheres and is suitable for aggressive chemical applications. It meets FDA conformance for service within food and pharmaceutical applications. TF1570 is the preferred material for fragile flanges, glass lined equipment or other applications that require higher compressibility.

TF1580:  Tealon TF1580 is filled with barium sulfate and is suitable for strong caustic fluids. It meets FDA conformance for service within food and pharmaceutical applications. 1580 can be used in a wide range of applications due to its vast resistance to most chemical products. It is compatible with strong acids along with strong caustics, making it the most diverse material within the Tealon family. With the off-white color of 1580, this material is also suitable for processes where contamination is not tolerated.

TF1590:  Tealon TF1590 is filled with silica and meets a wide range of applications. It is suitable for general service, strong acids and moderate caustic solutions. It meets FDA conformance for service within food and pharmaceutical applications.

TF1572 SAN:  Tealon TF 1572 SAN is suitable for service with a wide variety of aggressive media, but is specifically formulated to allow compliance for drinking water system components with NSF-61, from source to tap. Certification to NSF-61 provides assurance to a highest level that TF1572 SAN is safe for use in drinking water service. The high compressibility of this style makes it particularly suitable for use with stress sensitive and/or fragile flanged joints, e.g. glass, ceramics, plastic, etc.

24SH:  24SH is 100% pure, multi-directionally expanded PTFE.  It is universally employable 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 24SH makes repairing small damage and/or irregularities of the sealing area (flange surface) unnecessary.  Gaskets cut from 24SH are dimensionally stable, i.e. they do not get wider when compressed. This allows narrow flange faces to be sealed safely.
