General Purpose Silicone Custom Hcr Raw Materials Solid Silicone Rubber for

Product Description
What is HCR silicone?
Heat Cured Rubber is a silicone elastomer formed of straight chains with very
high molecular weight. The system will be cured with
either an organic peroxide crosslinker, or a platinum catalyst. HCR offers
great temperature and aging resistance.

Heat Cured Rubber elastomers have outstanding properties and are far superior
to conventional organic elastomers. They exhibit
exceptional mechanical strength at temperature and can be used at temperatures
ranging from -50°C to +300°C. The aging resistance
of these elastomers highlights their fundamental qualities such as the fact
that they are chemically inert, their photo-oxidative
stability and the absence of residual reactive groups once cured.

Related applications
HCRs outstanding properties are used in many different industrial applications:
sealing and piping in fluid circuitry (joints for
building construction and aeronautical applications, automotive gaskets, boots
and hoses), electrical protection (office equipment
safety cables and insulators for electrotechnical applications, spark plug
boots, cables and connectors for automotive
application), food, pharmaceutical and biomedical applications (tubes, profiled
The addition of various additives opens unlimited for customization of HCRs to
create solutions to all kind of existing and new
applications in Aerospace, Automotive, Healthcare, Oil & Gas, Construction,
Electronics. Most recent examples are heat transfer
additives for Electrical Vehicles, electrical conductive materials for Power or
Consumer Electronics and also antibacterial
solutions for Healthcare applications.
