High Hardness Drink Straw Clear Food grade Liquid Silicone Rubber Material Favtory Supplier price Baby mat
Description
Two-component Platinum-curing liquid silicone rubber RH5350 - 70 is used to make injection molds. It can be used to pour material for electronic and electrical parts, as well as to make molds for baby toys, baby soothers, artificial prostheses, fake human breasts, and soft silicone rubber products like bra pads, diving glasses, shoulder pads, patches, anti-slip mats, baby nipples, and pacifiers.
Key Features and Benefits
Vulcanisates consisting of RH5350 - 70 LSR are distinguished by the following properties:
· High transparency, high strength, good resilience, small deformation value, yellowing resistance and aging resistance;
·Comply with US FDA CFR 21.Part.177.2600 and European EN14350-2, Section 4.9 Volatile Compound Test Standards and European ROHS and REACH Standards;
·In the environment of 20 °C, the safe operation time is 3 days after the A/B components are mixed and sealed, and the safe operation time is shortened when the temperature rises;
