Thermoset plastics cure with a chemical reaction typically under
high heat and
 pressure.
Once cured they can not be melted back to to raw materials with
heat.
Thermo-set
plastic compounds start with Phenolic, Expoxy, Polyster or
Vinylester resin to form the basic materials. Fillers are then added
to attain the desired properties required for specific
application. Possible fillers include clay, glass, carbon
fibers, and kevalar fibers .
Advantages of thermoset plastic molding:
- High Heat
resistance
- Fiber loadings can have as as high
as
50-60% (Volume)
- High
compression strength
- Very
Stable
- Very
dimension constant
- Can
replace multiple parts with a single molded part that does not
require machining
