PTFE Carbon

Polytetraflouroethylene (PTFE) sealing solutions have been quite popular for several years now. PTFE is a fluorocarbon-based thermoplastic polymer, which exhibits excellent wear resistance, elasticity, and frictional properties. All these properties make it a popular choice for sealing materials. Nowadays, filled PTFE materials are available and they are used for building various types of sealing solutions. Carbon-filled PTFE is one such material that is chosen for its improved mechanical strength and several other properties. 

SSP Seals specializes in the design and development of various types of polytetraflouroethylene seals. We work with different types of filled PTFE materials and carbon-filled PTFE is one of the most common materials we work with. The seals made of this material are especially used in applications where they may be exposed to high thermal conductivity than PTFE. The carbon filled PTFE is a less abrasive material than glass-filled PTFE, which also increases its utility in applications where abrasiveness can be a concern. There are several manufacturers dealing with PTFE sealing solutions, however, what makes us different is our ability to deliver customized solutions to meet your exact requirements.

Properties of PTFE Carbon

Carbon-filled PTFE is available in different compositions depending on the material to filler ratio. Of this, PTFE 75% and 25% carbon is the most common ratio. Generally, carbon filler ratios may vary from 0.2% to 40%. The material properties will vary according. The following are some common properties of PTFE carbon that make it a popular choice for sealing solutions.  

  • Carbon-filled PTFE has excellent mechanical properties.
  • It can be used for building seals for high-pressure applications, as well as dynamic applications.
  • The material provides excellent chemical resistance and improved wear resistance when exposed to a load.
  • This material is highly economical over other PTFE materials.
