PET is a partly crystalline thermoplastic Polyester
based on Polyethylene-Terephthalate. This
material features outstanding dimensional stability
as it is virtually unaffected by ambient moisture.
A low coefficient of friction and excellent
wear resistance combined with low creep and
high E-modulus of elasticity in tension makes it
the choice material for moving parts. Hot water
resistance is low but it has better resistance
to acids than Nylon or Acetal. ZELLAMID1400 is produced without centreline porosity
and is approved for contact with food (FDA
and EU 10/2011). As it is more rigid than other
thermoplastics, please consult our machining
guidelines.
Applications:
Bushings and bearings, gears, cams, mandrels,
manifolds, wear strips, hamburger and nugget
dies, food piston pumps, valves and valve bodies,
feeder blocks, filter tracks, electrical insulators,
etc.
