liquid Silicone Rubber (RTV) is a type of silicone rubber made from a two-component system
Description
RUI-HE 6250 is a kind of two-component liquid silicone rubber for injection molding processes, consisted of part A and part B. It can be used to produce electronics keys supplies with high rebound and good resistance to yellow. All LSR are platinum cured (vulcanized) materials which are mixed in a 1 : 1 ratio by weight.
Key Features and Benefits
High transparency
Easy pigmentable with the LSR Color Pastes
High Viscosity
Good resistance to yellow
Rapid vulcanization
Fantastic durability
High rebound property
Sensational weather resistance
High stability to ozone and ultraviolet light
