Key sentence: Bio-based liquid silicone rubber with renewable feedstock receives FDA food-contact approval for reusable kitchenware and food molding applications.

A European silicone maker announced full FDA 21 CFR food-contact clearance for its new bio-based liquid silicone rubber on November 5. The material uses bio-methanol feedstock sourced from certified biomass, reaching 28% bio-based carbon content while matching the mechanical strength, heat resistance and transparency of fossil-based food-grade LSR. It eliminates the need for post-curing, cutting production cycle time for injection molded silicone bakeware, candy molds and baby feeding parts. Many food silicone exporters are chasing sustainability credentials to satisfy EU and US retail brand requirements. Traditional bio-silicone grades often had tear strength gaps and batch consistency issues, limiting mass molding adoption. This upgraded platform keeps low cyclic siloxane residuals and passes migration testing for repeated hot food contact. It works on standard LSR injection molding lines without equipment modification. Buyers can combine REDcert sustainability certificates with FDA reports for customs and brand audits. Food mold silicone manufacturers are testing this grade to upgrade their eco-friendly product lines for premium global buyers.
