Medical Grade Liquid Silicone Rubber for Protective Mask

Medical Grade Liquid Silicone Rubber for Protective Mask

Protective mask medical grade liquid silicone rubber is a non-toxic and harmless synthetic material with human affinity. Because of its good biocompatibility and biological stability, it is widely used in industrial protection, medical and other fields. Compared with solid high-temperature vulcanized silicon rubber, medical-grade liquid silicone gel has fast vulcanization, environmental protection, good fluidity, safety, and fully meets the requirements of food grade.
