Fördelar med PP

Relatively high fatigue strength.
Stiffer than PEHD.
Retains its mechanical properties better at high temperatures than PEHD.
Excellent dielectric properties.
Low density (floating).
Chemical resistance similar to polyethylene, but not the same tendency to stress cracking due to. surrounding medium.
Reinforced grades have a stiffness similar to unfilled nylon but at a lower price.
Mechanical and electrical properties are also maintained in water.
Non-toxic grades can be steam sterilized.

Becomes brittle below -20 ° C.
Degraded by UV radiation if it is not stabilized.
Attacked by oxidizing acids.
Thermal stability is reduced upon contact with copper.
PP-C material is easier to glue together with other materials, such as wood and aluminum than with itself.
