Modified free-flowing suspension PTFE of the 2nd generation for compression moulding and ram extrusion applications like shaped parts, skived films, seals and valve seats.

Special Features are:

  • Meets ASTM D 4894 Type III, Grade 2 classification
  • Produced by suspension polymerisation
  • Good mould filling behaviour
  • Very good free-flowing properties
  • Improved particle coalescence
  • Dense polymer structure with reduced void content
  • Low permeability
  • Substantially lower deformation under load (“cold flow”)
  • Good electrical and mechanical properties
  • Increased modulus of elasticity
  • Good weldability
  • Excellent chemical inertness
  • Low friction behaviour
  • Good flame retardance
  • Exceptional temperature resistance

  • Typical Properties:

    Modified PTFE moulding and ram extrusion powder is the preferred grade for shaped parts requiring very good free-flowing, good mechanical and electrical properties, a denser polymer structure, significantly lower deformation under load and improved weldability.
