Kareline® PPMS composites are a family of injection mouldable natural fibre reinforced thermoplastic composites.
- Kareline® PPMS EC gives exceptionally "natural/wild" appearance to moulded products (e.g. Kupilka, www.kupilka.fi). It can be coloured to "earth-colours".
- Kareline® PPMS COW is a natural white material with "egg shell-like" surface pattern. It can be easily coloured.
- When especially bright colours are needed, Kareline® PPMS CO is the right material.
The matrix plastic of all Kareline® PPMS composites is polypropylene. Polypropylene is homopolymer (Kareline PPMS EC) or copolymer grade (Kareline PPMS COW and CO).
The fibre used is ECF bleached long fibre Nordic soft wood pulp (cellulose). The fibre content of Kareline® PPMS composites is 10 - 55 weight% (for example Kareline® PPMS 5050 EC, Kareline® PPMS7525 COW). Customer tailor made grades are also available.
Kareline® PPMS composites are suitable for a wide variety of applications e.g. furniture, decorations, garden furniture and tools, interior design, handles of tools, technical applications, household applications, different appliances, in sauna and bathrooms, applications where glass reinforced PP is used.
If needed, it is possible to have Kareline® PPMS products with very beautiful and living surface structure and colours using Kareline® PPMS5050 EC modified composite.
Kareline® PPMS composites have a lot of good properties:
- Good mechanical properties
- Small shrinkages in injection moulding
- Very small thermal expansion. Good dimensional stability
- No sink marks in moulded parts, even in very thick walls
- Pleasant feel and appearance of surface; if needed very beautiful living/natural surface is possible
It is not recommended to use Kareline® PPMS under the following conditions:
- very low temperatures (under -25)
- Together with strongly oxidicing chemicals
