Easily Colored Non-Hazardous Pigments LSR 6250-40T® Liquid Silicone Rubber For Scuba Mask
Description
RUI-HE 6250-40T® 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 a high rebound and good resistance to yellow. All LSR are platinum cured (vulcanized) materials which are mixed in a 1: 1 ratio by weight.
Liquid Silicone Rubber Feature:
1. Fast-forming speed
2. Good Processability
3. Super-stable Physical Performance
4. Low deformation rate after compression
5. Good resilience
6. Injection molding
7. Non-hazardous pigments
8. It complies with the related specification of ROHS, has passed the detection of FDA and LFGB.

Operation instruction
Part A and B are packed in 20kgs pails or 200kgs drums respectively. When operating, part A and B can be injected directly to the heated mold from the original containers by mean of metering and mixing unit. At the mold temperature of 90-150℃, silicone rubber cures within minutes according to the size.
The pot life is 3-7days after mixing under 23℃. Clean pipe and machine when machine stoped for a long time.
