Daplen EC321T Borealis Polypropylene, Unspecified (Mineral Filler, 30%)

Product Description

EC321T is a mineral reinforced, elastomer modified PP compound, intended for injection moulding.
EC321T is developed especially for lateral protection and provides low thermal expansion, high stiffness and good impact at low temperature.

EC321T show excellent surface properties and mould shrinkage as ABS. The product is UV-stabilised.

EC321T has been developed automotive parts such as:

Injection moulded exterior trims and lateral protection

Injection moulded instrument panels
