is a thermoplastic, that is, it is one of a variety of
materials that have the property of becoming
hard and rigid when cooled and are moldable when heated.
or fuse when heated and harden and become rigid again when
cooled without undergoing any appreciable chemical change. Polyolefin
comes in many different chemical formulae (due to additives)
chemical and mechanical properties, including adhesion,
and varying thicknesses -- both of which
coefficient of expansion. Successful
long term bonding
of polyolefin to itself and to other substrates, requires careful
preparation and matching of the adhesive being used with the differing
COEs of the substrates
involved. BONDiTTM products
are among the few available that can be used to bond polyolefin
with other COE's for harsh environments and long term deployment
highest recommended product for bonding polyolefin is BONDiTTM
B-45TH or B-482TH or B-4682 depending upon the relative need
chemical resistance, bond strength, impact and vibration
resistance, heat resistance, and COE differential.
Our recommendation would change if a fast cure is needed, in which
case we recommend the use of BONDITTM B-536TH.
Other recommended products are hot melts BONDiTTM HM-502 or HM-505
with adhesion promoter, BONDiTTM A-43.
Among the other substrates to which polyolefins can be bonded
using BONDiTTM products
are: UHMW, Delrin, fluoropolymers, rubber,
polyethylene, polyolefins, polypropylene, polyurethane, silicone, thermoplastics,
thermoset, urethane, ceramics, glass, fiberglass, wood, metals, stone,
