Engineered
plastics include:
Ultra
high molecular weight polyethylene (UHMW)
Delrin or Acetal
Fluoropolymers such as Teflon
Polyethylene
Polyolefin
Polypropylene
Polyurethane
Thermoplastics
Thermosets
Urethane
Rubber including:
EPM and EPDM (ethylene propylene rubber)
Aflas
Nitrile
Polyisoprene and butyl
Polybutadiene (Styrine Butadiene Rubber or SBR) or Nitrile called buna N rubber)
Chloroprene, also called neoprene
Silicone RTV (Room Temperature Vulanized)
FKM Viton®, Tecnoflon®
Santoprene® (PP and EPDM)
Flouorosilicone Rubber
Polyurethane Rubber
Epichlorohydrine Rubber (ECO)
Polysulfide Rubber
Cholorsulfonated Polyethylene (CSM), (Hypalon®)
Most of these materials have been invented to provide better
resistance than natural materials like wood or metal to
wear and impact,
chemicals, degredation from environmental sources
such
as moisture, temperature fluctuation and UV.
One of the properties
of engineered plastics that make them it difficult
to bond to, the surface slickness,
is
the
result
of the
manufacturing process. Engineered plastics can be bonded
to themselves and to other plastics and substrates including
glass, ceramic, metal, stone, aggregate and concrete among others,
but
require careful
preparation
and BONDiTTM brand
adhesives manufactured by RELTEK LLC. BONDiTTM products
are among the few available that can be used to bond
engineered plastics to substrates
with differing coefficients of expansion
(COE). BONDiTTM products are
renowned for their resistance to harsh environments and
for
withstanding
long
term
deployment without debonding.
