ABS (DIN designation)
ABS is a thermoplastic copolymerisate made from acrylonitrile,
butadiene and styrene monomers. Using different
combinations of these monomers, wide-ranging different
ABS types can be manufactured offering a wide spectrum
of different properties by means of branching or copolymerization.
H ABS H is classified as an amorphous thermoplastic.

Summary
TECARAN ABS is harder and more scratch-proof than PET
and POM but with lower thermal stability. The characteristics
of the basic ABS type offer wide scope for modification
by varying the proportion of components. By modifying
with PC and PBT, a wide variety of tough, impact resistant
O
types can be created, primarily for injection moulding.
