Description

Modified semi-free-flowing suspension PTFE of the 2nd generation for moulding applications like diaphragms, bellows, shaped parts and skived films.

Special Features are:

Meets ASTM D 4894 - Type IV, Grade 2 classification

Produced by suspension polymerisation

Homogenous mould filling and reduced moulding pressure

Substantially lower deformation under load (“cold flow”)

Improved particle coalescence

Better surface finish

Dense polymer structure with very low void content

Low permeability

Good weldability

Improved flex life

Good electrical and mechanical properties Excellent chemical resistance

Low friction behaviour

Good flame retardance

Exceptional temperature resistance

Typical Properties:

PTFE moulding powder with semi-free-flowing properties and high bulk density is the preferred grade for shaped parts requiring improved flexlife properties, a denser polymer structure, significantly lower deformation under load and very good mechanical properties.
