Thermoplastics and Teflon

Kor-Pak is an all-inclusive source for Thermoplastics and Teflon, including sheets, rods, and finished products including custom machined parts

Description

Kor-Pak provides various grades of Thermoplastics and Teflon materials, sold in sheets as well as machined to custom sizes.  Materials offered by Kor-Pak include:

PTFE

The base characteristics of PTFE are the ones offering a unique combination of:valvoline

  • low coefficient of friction
  • excellent chemical inertness
  • non-adhesive surface
  • wide temperature range withstanding (–200° C to +260° C), excellent dielectric properties.

The most popular and processed materials of which IPM stock quite large quantities and owns large production capacity:

  • PTFE G400
    Extruded tubes and rods;
    Molded tubes, rods and sheets;

FEP

Fluorinated thermoplastic material with excellent thermal, electrical and chemical inertness properties.
Widely used for different industrial applications for its excellent chemical resistance up to 200° C.
The most common format being, skived film, it can be used as non-stick material in the compression moulding processes, or melting material between fluorinated resins.

PFA

 

Fluorinated thermoplastic material, offers the advantages of being thermo-processed whilst at the same time having the properties of PTFE, with excellent chemical and mechanical resistance for applications up to 260°C.
Thanks to its fluidity during the processing, the final products in PFA – especially the skived film – are absolutely porous- free, hence very suitable for electrical applications.

It’s a semi-crystalline fully-fluorinated melt processable fluoropolymer which offer the highest temperature rating and broadest chemical resistance of all melt processable fluoropolymers. It is an ideal choice for extreme thermal and chemical environments. MFA exhibits the outstanding thermal behaviour and chemical resistance found in PTFE, PFA and FEP.

In addition, parts made with MFA have been shown to have smooth finished surfaces. This makes MFA a good candidate for the semiconductor, electronics and biologic applications.
