Medical Grade Liquid Silicone Rubber (LSR) 6250-50YH is specifically designed for manufacturing silicone respiratory masks, including CPAP masks, oxygen masks, and other breathing support devices. The material provides excellent softness, elasticity, and biocompatibility, ensuring a comfortable and secure fit for prolonged use.
Respiratory masks require materials that can maintain stable sealing performance, skin compatibility, and durability under repeated use. With a Shore A hardness of 50, this liquid silicone rubber offers an optimal balance between flexibility and structural support, allowing masks to conform closely to facial contours while maintaining their shape.
The material also features excellent resistance to deformation, aging, and repeated sterilization, making it highly suitable for long-term medical applications.
