is a FLUOROPOLYMER which are organic compounds consisting
of fluorine and carbon atoms
but may also contain oxygen or hydrogen.
found fluoropolymers are tetrafluorethylene (TFE), polytetrafluoroethylene
(PTFE or Teflon®), perfluoroalkyoxy (PFA),
perfluoroethylenepropylene (FEP another grade of Teflon®),
modified PTFE (another grade of Teflon®),
polyvinylidenefluordie (PVDF or Kynar®),
ethylene-tertrafluoroethylene (EFE or Tefzel®)
and ethylene-chlorotrifluoroethylene (ECTFE or Halar®).
Each of these fluoropolymers has chemical and physical
properties that differ from one another in durometer, impact
resistance, tensile strength, melting point, chemical and moisture
resistance, and elongation. Among the many uses of fluoropolymers
of pumps, valves and piping
of the properties of fluorpolymers that makes it difficult

it requires careful preparation, matching of the adhesive's elongation
to the coefficient of expansion (COE) of the materials being
bonded. We recommend the use of BONDiTTM brand
products are among the few available
can be used
or fluoropolymer substrates to themselves, and to other substrates
for harsh environments and long term deployment without debonding.
The RELTEK Teflon Bonding Kit including an etchant to prepare
the fluoropolymer surface to be bonded and BONDiTTM B-45TH
adhesive. The kit may be modified to include any of the BONDiTTM adhesives
Our highest recommendation for bonding Teflon
(after the substrates are properly prepared)
is our BONDiTTM B-45TH. In the case of
PVDF and ECTFE, no preparation of the substrates is required to
use BONDiTTM products.
Our recommendation would change if you're looking for higher chemical
resistance, in which case we recommend the BONDiTTM B-4811.
If high temperature resistance is required, please call us at (707)
284-8808 for a specific recommendation for your application.
the other substrates which Teflon can be bonded
to using BONDiTTM
are: UHMW, Delrin, other fluoropolymers, rubber,
polyethylene, polyolefin, polypropylene, polyurethane, silicone, thermoplastics,
urethane, glass, ceramics, wood, metals, stone, aggregate and concrete.
