Silicone Rubber Platinum-Based Catalysts | SIMTEC
Description of the Platinum Chemical Reaction that Forms Silicone Rubber. The silicone industry extensively uses the platinum-catalysed hydrosilation reaction in which a silicon-hydrogen (Si-H) bond is added across an unsaturated carbon-carbon double bond (C=C) of an olefin, resulting in the formation of a silicon-carbon (Si-C) bond.
Injection Molding of Liquid Silicone Rubber: LSR the - SIMTEC
One of the components contains the platinum-based catalyst. A coloring paste as well as other additives can also be added before the material enters the static mixer. In the static mixer, the components are mixed well and transferred to the cooled metering section of the injection molding of liquid silicone rubber machine.

Curing Speeds in Silicone Rubber | SIMTEC
Platinum Catalyst Curing. For liquid silicone rubber cured with a platinum catalyst, the increase of the processing temperature has an effect similar to increasing the amount to be cured. To optimize the speed in this case, in general, it could be said that for every ~10°C, the cure rate could be increased in approximately 20-25%.

Liquid Silicone Rubber vs High Consistency Rubber | SIMTEC
Silicone rubber is a thermoset with a backbone of alternating silicone and oxygen atoms with methyl or vinyl side groups. There are two types of silicone rubber: solid and liquid. The basic structure of the two types of silicone rubber is the same, but curing and processing are radically different.

SIMTEC is a leading, US-based, global manufacturer exclusively focused on the customized, serial production of Liquid Silicone Rubber (LSR), overmolded and 2-Shot (LSR/Thermoplastics) injection
Silicone Rubber Condensation and Addition Cure Explained
Addition cure silicones use a platinum-based catalyst (usually 10%) while condensation cure silicones need a tin-based catalyst (usually 5%). The platinum catalyst used in addition cure silicones is susceptible to some chemicals like nitrogen, sulphur, phosphorus, sulphur vulcanized rubbers and condensation cure silicone rubbers.
