Silicone Elastomer

Good mechanical properties
Low compression set at elevated temperatures
Heat stable (indefinitely up to 180ºC)
Flexible at low temperatures (-40ºC)
Sterilizable
Hydrophobic
High dielectric strength
Low flammability
Durable
Pigmentability
Can be food grade compliant
Probably the single most important characteristic of silicone elastomers is their unique ability to retain their mechanical properties over a wide temperature range.
