Product description
Liquid silicone rubbers of the RUI-HE RH6250-50
series are paste-like, easily-pigmentable twocomponent compounds with short curing times.
Their vulcanizates are noted for their high transparency and excellent mechanical and electrical properties.
When heat stabilizers are added, the products can be used within a temperature range of -55 °C to +230 °C,
and for a short time up to +300 °C.
