Kareline® POMS6040
聚甲醛(POM)共聚物
木纖維
產(chǎn)品說(shuō)明:
The matrix plastic of Kareline® POMS is co-polyacetal
(POM). The fibre used is ECF bleached long fibre Nordic soft wood pulp
(cellulose). The fibre content of Kareline® POMS composites is 10-40 weight%
(for example Kareline® POMS6040, Kareline® POMS7030). Customers made grades are
also available.
Kareline® POMS composites have a lot of good properties:
High rigidity
Good impact strength as natural fibre composite
Excellent abrasion resistance
Good chemical and stress cracking resistance
Easy to machine
Low friction surfaces
Small shrinkages in injection moulding
Dimensional stability and absence of shrink marks
