Main characteristics


Excellent wear resistance, self-lubricating mechanical strength higher. However, it has high water absorption and poor dimensional stability

,
It can maintain strong strength and stiffness at higher temperatures.
The degree to which it remains hygroscopic after molding mainly depends on the composition of the material, wall thickness and environmental conditions.

The impact of hygroscopicity on geometric stability must be considered when designing products. In order to improve the mechanical properties of
, various modifiers are often added. Glass is the most common additive, and sometimes synthetic rubber such as
D
and
are added to improve impact resistance.
is less viscous and therefore flows well (but not as well as
). This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. The shrinkage rate of

and
is between
%~%
Adding glass fiber additives can reduce the shrinkage rate to

. The difference in shrinkage rate in the process direction and the direction perpendicular to the process direction is large.
Resistant to many solvents but less resistant to acids and some other chlorinating agents.
