Products / Modifications<br />
TECAFINE PP (PP)<br />
Unreinforced basic type, natural<br />
TECAFINE PP GF30 (PP GF)<br />
Glass fibre reinforced for high<br />
strength, rigidity, hardness and low<br />
thermal expansion, dimensional<br />
stability, preferred use for injection<br />
moulding<br />
TECAPRO MT (PP)<br />
Special type, modified for use in<br />
medical technology, biocompatible<br />
Application examples<br />
TECAFINE PP: large-sized chemistry apparatus, acid-proof<br />
construction and acid baths, valves, galvanizing apparatus,<br />
pickling and etching baths, low-temperature exhaust gas<br />
flues, filter plates for filter presses, waste water plants,<br />
waste water piping systems, fittings made of extruded<br />
semi-finished products, transport crates for food, filter<br />
components, fittings, containers, food processing plants<br />
exposed to high levels of thermal and chemical stress. Used<br />
in large-format press platens with low warpage and good<br />
welding properties for chemical plants manufactured using<br />
daylight presses. TECAPRO MT: biocompatible material<br />
for use in medical technology, trays for the cleaning,<br />
sterilization and storage of different medical devices and<br />
components used in medical applications, simple handles,<br />
certain geometry adaptation models, body contact plates for<br />
mammography.<br />
Summary<br />
<strong>The</strong> main difference between TECAFINE PP and TECAPRO<br />
MT is that TECAPRO MT is based on specially heat-stabilized<br />
PP homopolymer. This allows it to resist higher thermal<br />
stress during extended tempering, resulting in a more<br />
stress-relieved product and reducing the tendency to warp<br />
as a result of repeated super-heated steam sterilization.<br />
Easy to machine into dimensionally stable lightweight<br />
components.<br />
