Product Description
The matrix plastic of Kareline® PSMS is polystyrene. The fibre used is ECF bleached long fibre Nordic soft wood pulp (cellulose). The fibre content of Kareline® PSMS composites is normally 10-20 weight% (Kareline® PSMS9010, Kareline® PSMS8020). Customer tailormade grades, e.g. with higher fibre content, are available.

Kareline® PSMS gives a very beautiful natural appearance to products in applications where no absolute mechanical properties are needed but where excellent surface quality and fascinating outlook are a desired property e.g. packaging of cosmetics or jewellery. Material has also very good dimensional stability in moulding and as a product.

Kareline® PSMS composites have a lot of good properties:
  • High rigidity
  • Excellent abrasion resistance
  • Pleasant feel of surface and beautiful natural surface appearance
  • Problem-free surface treatment
  • Good dimensional stability
