Food Grade Non-Post Cured Liquid Silicone Rubber for Baby Products and Food Contact Parts

Product Overview

Food grade liquid silicone rubber is widely used in baby care and food-contact applications due to its safety, durability, and flexibility. Non-post cured liquid silicone rubber eliminates the traditional secondary curing process, helping manufacturers improve production efficiency while maintaining excellent product quality.

The 6250-70FV liquid silicone rubber is a two-component platinum-cured material developed for injection molding. It offers excellent transparency, strong mechanical properties, and low volatile content (VOC ≤0.5%), making it suitable for high-quality baby products and food-contact components.

This material meets food-contact safety requirements such as LFGB standards and is ideal for producing baby products that require durability and safety. Its stable rubber formation rate and strong tear resistance allow manufacturers to create reliable products such as baby pacifiers, bottle nipples, breast pump accessories, teething toys, and food equipment parts.
