Polyphthalamide (aka. PPA, High Performance Polyamide) is a
thermoplastic synthetic resin of the polyamide (nylon) family that
is used to replace metals in high temperature automotive
applications, as the housing for high temperature electrical
connectors and multiple other uses. It has found a degree of favor
for use in cutlery. Cold Steel has advertised the glass fibre
reinforced series as being stealthy (due to them not being detected
by metal detectors and having no metallic reflections)
As a member of the nylon family, it is a semi-crystalline material
composed from a diacid and a diamine. However, the diacid portion
contains at least *5% terephthalic acid (TPA) or isophthalic acid
(IPA). TPA or IPA are aromatic components which serve to raise the
melting point, glass transition temperature and generally improve
chemical resistance vs. standard aliphatic nylon polymers.
