applications, components for food processing plants<br />
Summary<br />
Products based on PET are used where moisture absorption<br />
must be avoided and where dimensional stability is<br />
required in conjunction with strength. Lower water absorption<br />
and thermal expansion than with PA and POM make<br />
PET ideally suited for dimensionally stable precision components<br />
with minimal environmental dependency. When<br />
used in food-related applications, resistance to typical<br />
cleaners plays a decisive role. PET is more resistant to different<br />
cleaning acids than POM and PA, but conversely<br />
does not tolerate alkaline cleaning agents (caustic soda).<br />
<strong>The</strong> material TECAPET is a special modification providing<br />
improved toughness, better sliding friction properties with<br />
slightly reduced strength, and primarily improved machinability.<br />
TECAPET black is the black dyed version with improved<br />
UV protection for external applications.<br />
TECAPET TF is a variant with improved sliding friction<br />
properties with added polymer solid lubricant TECADUR<br />
PBT GF30. It is the glass-fibre reinforced modification<br />
based on the related but significantly tougher PBT for higher<br />
strength requirements, high rigidity and low thermal<br />
expansion, making it ideally suited for structural components<br />
with a high level of precision used in electrotechnical<br />
applications, precision mechanics and mechanical engineering.<br />
PET is in any case highly rigid. Due to the high<br />
level of brittleness, with the addition of glass fibre it could<br />
not be further processed without damage.<br />
