At very low temperatures silicone will stiffen and become "glass-like".
It will not respond like a rubber at these temperatures and will not react to the stimuli placed upon it i.e. deformation loads will need to increase up to a point where the material may shatter.
Primasil has developed phenyl-based compounds for products in operation in these environments (below the –55°C which general purpose silicone can withstand). These low temperature resistant compounds can be moulded, extruded, or calendered, and offer excellent resistance to temperatures down to –100°C.
