RH6250-40YH Medical Grade Liquid Silicone Rubber is a high-performance platinum-cured silicone material specially developed for manufacturing scuba diving mouthpieces and breathing accessories. The material provides an ideal balance of comfort, durability, and safety, ensuring reliable performance in demanding underwater environments.
Scuba diving mouthpieces require materials that can withstand continuous biting, saltwater exposure, and long-term use. RH6250-40YH offers excellent elasticity, tear resistance, and fatigue resistance, making it highly suitable for mouthpiece applications where both flexibility and strength are critical.
With a Shore A hardness of approximately 40, this liquid silicone rubber provides a comfortable biting experience while maintaining sufficient structural strength to prevent deformation during prolonged use. The material is also highly resistant to seawater, UV exposure, and aging, ensuring long service life even in harsh marine conditions.
In addition, RH6250-40YH features low odor, high purity, and excellent biocompatibility, making it safe for prolonged oral contact. Its stable performance in LSR injection molding allows manufacturers to produce mouthpieces with smooth surfaces, ergonomic designs, and consistent quality.
