Ultra-Soft Food Grade Liquid Silicone Rubber for Safe and Durable Baby Nipples
Product Overview
RH6250-30FV Liquid Silicone Rubber is a food-grade, platinum-cured non-post-cured LSR specially designed for manufacturing baby nipples and infant feeding accessories. The material offers an ideal balance of softness, elasticity, and durability, ensuring a comfortable feeding experience and long service life for baby products.
Compared with conventional silicone materials that require secondary curing, this non-post-cured liquid silicone rubber significantly improves production efficiency by eliminating the post-curing process. Manufacturers can reduce energy consumption, shorten production cycles, and maintain consistent product quality.
This material provides excellent transparency, elasticity, and tear resistance, making it particularly suitable for baby nipples that require softness and high safety standards. The stable mechanical properties also ensure reliable performance during high-precision LSR injection molding, enabling manufacturers to produce smooth, hygienic, and durable silicone nipples.
With low volatile content and excellent processing stability, this liquid silicone rubber meets strict food-contact requirements and is widely used in infant feeding and baby care products.
