High-Purity PTFE Products

by ISP | April 21, 2016

High-purity PTFE products are used in medical, laboratory, scientific, and other applications where cleanliness is essential. They’re made of specialized grades of polytetrafluoroethylene (PTFE), a synthetic fluoropolymer that’s available under a variety of brand names, including Teflon® from DuPont**. Interstate Specialty Products die cuts high-purity PTFE products at its ISO 13485:2016 facility in Sutton, Massachusetts and has additional packaging and assembly capabilities for sensitive components.

High-Purity PTFE ProductsWhat Is High-Purity PTFE?

Advantages of High-Purity PTFE:

  • provides chemical resistance
  • thermal stability
  • cryogenic properties
  • a low coefficient of friction
  • high surface resistivity
  • flame resistance
  • a low dielectric constant

High-purity PTFE materials are processed in a strictly-controlled cleanroom environment that prevents the introduction of impurities, such as carbon-based contaminants. Production occurs with minimal material handling, and high-quality resins are used for enhanced material properties. Materials are traceable and static dissipative grades are available.

Types of High-Purity PTFE Materials

High-purity PTFE products are made from virgin materials or specialized compounds. Typically, these compounds are customized or enhanced with fillers.

  • Glass fiber and carbon fillers are used to increase the compressive strength of high-purity PTFE
  • Bronze and molybdenum sulfite fillers increase hardness or stiffness
  • Graphite reduces the coefficient of friction

High-purity PTFE products can also be made from materials that are FDA approved or that meet ASTM or NSF standards.

Clean Room Manufacturing

Interstate Specialty Products die cuts high-purity PTFE products from molded sheets or continuous rolls of materials. Our cleanroom manufacturing capabilities include precision die cutting and rotary die cutting under controlled temperature and humidity. As a verified and certified ISO 13485:2016 facility, we’ve proven that our cleanroom room die cutting services meet strict requirements for medical device manufacturing.

Applications for High-Purity PTFE Parts

In addition to medical, laboratory, and scientific applications, high-purity PTFE products are used in semiconductor manufacturing and with electrical and electronic equipment. With its excellent insulation and dielectric properties, very smooth surfaces, and low friction, high-purity PTFE products are used in insulators and as other equipment components.
