Product Description
Daplen AK4504 is a 30% mineral and elastomer modified soft polypropylene compound intended for injection moulding.

Daplen AK4504 has a very high MFR, high softness and excellent sound dampening properties. This makes it suitable for moulding of thinwalled parts where excellent noise dampening is required. The product is UV stabilised and thus suitable for exterior parts with very low wall thickness and high demands on noise reduction.

Daplen AK4504 is optimised to give high quality parts with the best production efficiency.
