SQUARE® LIM3900-XX A/B
SQUARE® LIM3900-XXA/B is a two-part,platinum curable,liquid silicone rubber for injection molding processes.This silicone rubber is particular developed for the manufacturing of baby nipple and bottles with high transparence,tensile and tear strength. All LSR are platinum cured materials which are mixed in a 1:1 ratio by weigtht.
Key Feature:
- High transparency
- High tensile strength and high tear strength
- Good rebound property.
- Excellent thermal and cold stability ( -50℃-230℃)
- Low yellowing, high elongation，low distortion
- Outstanding resistance to aging
- Low yellowing
- Meet USA FDA CFR 21.part.177.600,EN 14350-2-2004,Part 4.9 test standard of volatile compound,CN GB 28482-2012 and Europe ROHS and REACH standar.
