What is Silicone Rubber | How is Silicone Made?
Silicone rubber is an extraordinary material
Tough enough to withstand the demands of jet engines and safe enough to use for baby bottle teats!
A high performance polymer originally developed to insulate electric motors and generators, silicone rubber is derived from silicon metal and silica sand.
Silicone rubber is typically supplied in one of three forms:
- a room temperature vulcanisation (RTV) kit
- a liquid
- a high consistency rubber (HCR)
Primasil are the UK leaders in the formulation and processing of high consistency silicone rubber, and are experts at moulding liquid silicone components.
In its uncured (un-vulcanised) form, the consistency of HCR silicone ranges from soft putty to cheddar cheese! This is in sharp contrast to most other rubbers, which have a much higher viscosity.
