6250-70KD A/B two part Liquid Silicone Rubber high adhesion
industrial seals part Antistatic
Description
Rui-He 6250-70KD A/B® 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
the 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
- Sensational weather resistance
- Fantastic durability
- High rebound property
- Fast curing
- Neutral odor and taste
- Good resistance to yellow
- High stability to ozone and ultraviolet light
- Easy pigmentable with the LSR Color Pastes
