microelectronics industry, lamp holders.
Summary
The amide groups have elevated moisture absorption and
also provide very good toughness, but demonstrate dimensional
changes and limited hydrolysis resistance.
For use in the higher temperature range, preliminary drying
is advisable in order to prevent hydrolytical damage.
Components machined as semi-finished products undergo
thermal treatment at the end of the polymerization process,
which simultaneously lends them improved abrasion resistance
on running surfaces in conjunction with oxidation
of the surface.
