50 Durometer FDA Grade Solid Silicone — Technical Overview & FAQs
Product Overview
50 Durometer FDA Grade Solid Silicone Rubber is a medium-firm, platinum-cured silicone elastomer designed for applications requiring food-contact safety, durability, and balanced mechanical performance.
Certified to FDA 21 CFR 177.2600, this material is odorless, tasteless, non-toxic, and ideal for environments that demand cleanliness, high temperature resistance, and long-term sealing reliability.
At 50 Shore A, this grade offers a perfect mid-point between flexibility and strength—making it suitable for equipment gaskets, processing seals, medical and lab devices, and food-grade machinery components that require controlled compression and excellent dimensional stability.
Applications
Medium-compression sanitary and food-processing gaskets
Beverage and dispensing system seals
Medical and laboratory equipment (non-implant)
Pharmaceutical manufacturing equipment
Oven, heater, and high-temperature food equipment seals
FDA-compliant die-cut gaskets, strips, and extruded profiles
