Food Grade Silicone Bottle Brush
Silicone Toothbrush, also called as Custom Silicone Toothbrush, Food Grade Silicone Toothbrush, Silicone Baby Toothbrush, is made of Liquid Silicone Rubber by liquid silicon rubber injection molding. Liquid Silicone Injection Molding are widely used for automotive applications, food storage products, electronics, infants products and medical devices.
Liquid Silico Rubber is a kind of non-toxic, heat resistant, high-resilience, flexible thermosetting material. Besides, non-reactive, elongation, tear strength, resistant to extreme environments are LSR's advantages.
Liquid Silicon Rubber's vulcanization behaviors: Low viscosity, fast curing, shear thinning and higher thermal expansion coefficient.

Liquid Silicon Rubber-Five Features:
Liquid Silicon Rubber-physical form
LSR----liquid state with liquidity
Liquid Silicon Rubber-applications
Liquid Silicon is food-grade and skin-friendly, which can contact food and human body directly. But its application is limited, mainly in infant series, kitchen wares and medical products.
Liquid Silicon Rubber-safety
Liquid Silicon Rubber is a kind of high transparent and safe food-grade material through closed batch charging forming, without adding vulcanizing agents during molding.
