All walks of life require products such as polytetrafluoroethylene or expanded polytetrafluoroethylene for multiple purposes. Expanded PTFE suppliers modify PTFE compounds to provide the required mechanical, thermal and electrical properties for industrial applications. Let us discuss more about PTFE and expanded PTFE sheets to help you choose the right one for your specific application.
1. What is PTFE?
Polytetrafluoroethylene, commonly known as PTFE or Teflon, is a strong material used in many industries. Both polytetrafluoroethylene and expanded polytetrafluoroethylene have good chemical resistance. In addition, expanded polytetrafluoroethylene has better creep resistance and cold flow properties.
PTFE has the following key characteristics:
- It can perform well in environments up to 260 degrees Celsius.
- Thecoefficient of friction of PTFE is low.
- The PTFE material is durable and can withstand wear and tear.
Use PTFE
Some industries PTFE is ideal for processing:
- Petrochemical
- paint
- Solvent
- Corrosive chemicals
- Media with oxidizing properties
- mineral oil
- Food and pharmaceuticals
- Glass line reactor and column
Teflon is odorless. It is non-corrosive, so it will not contaminate the contents in contact with it. This is one of the reasons why it is approved for use in the food processing industry.
2. What is expanded PTFE?
There are several well-known manufacturers of PTFE sheets who produce expanded PTFE sheets. It is made of 100% virgin polytetrafluoroethylene.
The salient features of expanded polytetrafluoroethylene are as follows:
- Expanded PTFE provides excellent resistance to cold flow and creep.
- EPTFE is a very popular sealing material because of its high compressibility.
Use ePTFE
If PTFE is a strong material, then why do we need PTFE? Use of ePTFE has the following benefits:
- Eptfe has good adaptability to the sealing surface.
- Expandable PTFE can be customized to obtain the required hardness, surface energy, stiffness and more.
3. PTFE sheet VS ePTFE sheet: How to Choose?
A variety of excellent properties can be found in ePTFE and PTFE. Both are applicable to multiple industries, including the food industry. However, if you want to enhance the properties of PTFE for your application, you should choose ePTFE.
Here are some more reasons to choose expanded PTFE:
- eptfe has a multi-directional fiber structure, which makes it have excellent performance under high surface pressure.
- In extreme environments, ePTFE sheets are more effective than PTFE sheets.
- eptfe is tailored for extreme safety requirements, such as sealing flanges in pipelines that transport oxygen.
Expanded ePTFE sheets have better performance than PTFE sheets. The huge demand for this flexible material has led to the availability of expanded polytetrafluoroethylene suppliers offering different densities, heights, and sizes. PTFE sheet, as well as expanded PTFE sheet, sheet or prefabricated gasket provided by the manufacturer.
