• Nylon
Nylon refers to polymers containing the amide, ,
grouping. Nylon 6 and nylon 66 are the most common nylons. They
are very tough and wear resistant.
• Polycarbonates
Polycarbonates are condensation polymers made from phosgene and
bisphenol A. They have high impact strength and are used in glaz-
ing, helmets, and appliance casings.
• Phenolics
A thermoset resin used for engineering purposes.

Engineering resins
are polymers that have outstanding physical properties
such as thermal stability, chemical resistance, self-lubrication, weather resis-
tance, etc. Generally, they are thermoplastics. They are gaining in importance
in automobile manufacture as metal replacements to provide lighter weight
cars.
