Description

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

Special Features are:

Meets ASTM D 4894 Type III, Grade 1 classification

Produced by suspension polymerisation

Improved particle coalescence

Dense polymer structure with reduced void content

Low permeability

Substantially lower deformation under load (“cold flow”)

Very good electrical and mechanical properties

Improved gel stability

Increased modulus of elasticity

Good weldability

Improved flex life characteristics

Excellent chemical inertness

Low friction behaviour

Good flame retardance

Exceptional temperature resistance

Typical Properties:

PTFE moulding powder with very small particle size is preferred for moulded parts requiring very good mechanical and electrical properties, a denser polymer structure, improved gel stability and flex life characteristics.
