Polypropylene - PP Copolymer

Polymer Type

Thermoplastic

Advantages

Good impact properties even at low temperatures and slightly increased elongation at break compared with unmodified PP homopolymer.

Disadvantages

Low stiffness and strength reduced flow properties and higher mould shrinkage than unmodified PP homopolymer.
