PTFE Sheet And Expanded PTFE Sheet Which One Suits Your Needs The Best


Different Industries require different type of gasket for different equipments.  PTFE & Expanded PTFE has unique features. These gaskets provide desired mechanical, thermal and electrical properties for industrial application.

What is PTFE?

In different industrial applications, there are many components that play an important role. PTFE Gaskets are one of those widely-used components across all industries. PTFE or Polytetrafluoroethylene that is commonly known as TEFLON is used as a gasket material by gasket manufacturers because of its physical, chemical & electrical properties.

Modified PTFE gasket sheets are used as sealants for specific purposes too. Uniklinger Ltd is one of the manufactures of this type of gasket with Special Name UNISIL Soft chem.

UNISIL soft-chem possesses universal resistance against common chemicals, except melted alkali metal, fluorine at liquid and gas status. UNISIL soft-chem meets the FDA requirements, doesn’t have any corrosion and is able to be stored without any time limits.

Some of Key Features of UNISIL Soft Chem are as follow:-

  • 100% Pure P.T.F.E.
  • Good flexibility
  • Highly compressible
  • Resistant to creep and cold flow
  • Low compressive load to seal
  • Can seal rough or damaged flanges

Usage of PTFE

Some of industries where PTFE is ideal to use

  • Oil & Solvent companies
  • Chemical Industries
  • Food & Pharma
  • Reactors & Different Columns
  • Oxidizing Media

Uniklinger is one of the manufactures who provide PTFE gasket with FDA Approval. This is one of the reasons this gasketis  used in food industries widely.

What is Expanded PTFE?

Expanded PTFE is a sealing agent that is made of 100-percent pure PTFE that can be acquired through a reputed Expanded PTFE Sheet Manufacturer. The expansion process produces a microporous fibrous structure which gives the product its unique mechanical properties.

In addition, expanded PTFE is a perfect sealant for sealing glass and plastic flanges and pressure vessels.

Characteristics of Expended PTFE-

  • E PTFE gives great strength & tunable porosity that is unique feature.
  • It has high flexural strength, even in low temperatures, high electrical resistanceand dielectric strength.

Usage of ePTFE

Different uses of e PTFE are as follow:-

expanded PTFE is used in petrochemical, food and pharmaceutical industry in temperature range from -240°C to +270°C.

PTFE Sheet or ePTFE Sheet – Which one should you choose?

Both PTFE and ePTFE are materials with excellent properties. Both are suitable for use in several industries including the food industry. However, you should choose ePTFE if you want enhanced PTFE characteristics for your application.

Here are some more reasons to choose an expanded PTFE:

  • Maintains airflow at a reduced filter differential pressure (DP), therefore energy absorbed by the fan is reduced.
  • E-PTFE is the most unusual fluoropolymer and exhibits the best performance in terms of temperature, chemical resistance and non-stick properties.
  • Excellent for use of uneven/damaged flanges.

UKL Offers both PTFE as well as Expended PTFE for Various Application. PTFE sheets, as well as expanded PTFE sheets, are offered by manufacturers as sheets or pre-fabricated gaskets based on the requirement.
