Product Overview

It is a food-grade non-post-cured Liquid Silicone Rubber (LSR) developed for the production of baby feeding products such as baby nipples, pacifiers, and breastfeeding accessories. This platinum-cured two-component silicone material provides excellent softness, transparency, and mechanical strength, making it ideal for high-safety infant products.

Unlike conventional silicone materials, RH6250-25FV does not require post curing, which helps manufacturers significantly reduce energy consumption and production time while maintaining stable product quality. The material offers excellent elasticity, tear resistance, and low volatile content, ensuring compliance with strict food-contact standards. Liquid silicone rubber is widely used for baby products due to its flexibility, durability, and biocompatibility.

RH6250-25FV also provides outstanding processing performance in LSR injection molding, allowing manufacturers to produce soft, durable, and hygienic baby nipples with excellent surface quality.
