Product Overview
50 Durometer Translucent FDA Grade Solid Silicone — Technical Overview & FAQs
Product Overview
50 Durometer Translucent FDA Grade Solid Silicone Rubber is a medium-firm, platinum-cured silicone elastomer engineered for food-contact safety, high durability, and balanced mechanical strength.
Compliant with FDA 21 CFR 177.2600, it is odorless, tasteless, non-toxic, and ideal for food & beverage processing, pharmaceutical manufacturing, sanitary equipment, and medical device sealing (non-implant).
At 50 Shore A, this grade provides an ideal midpoint between flexibility and rigidity—offering improved structural support compared to 30A and 40A materials while still maintaining excellent elasticity and compression recovery.
The translucent aesthetic is preferred in hygienic, cleanroom, and medical environments where visibility and cleanliness are essential.
Applications
Medium-firm sanitary gaskets and food-safe seals
Beverage and dispensing system gaskets
Pharmaceutical manufacturing equipment
Industrial sanitary enclosures
Medical device housings and diagnostic equipment (non-implant)
FDA-compliant die-cut seals, strips, sheets, and extruded profiles

FAQs
What is 50 Durometer Translucent FDA Silicone used for?
It is used in sanitary gaskets, food-processing systems, beverage equipment, pharmaceutical equipment, and medical device sealing where a medium-firm FDA-approved elastomer is required.
How does 50A silicone differ from softer FDA grades like 30A and 40A?
50A silicone provides:
Higher sealing pressure
Improved structural integrity
Better durability under compression
Enhanced strength for demanding sanitary environments
It remains flexible but offers more support than lower-durometer grades.
Is 50 durometer silicone safe for food-contact applications?
Yes. This material is compliant with FDA 21 CFR 177.2600, making it safe for incidental food contact in hygienic and processing systems.
Can translucent FDA silicone withstand high temperatures and cleaning cycles?
Absolutely. It performs reliably from –80 °F to +450 °F, and withstands:
Hot water washdowns
Steam
CIP cleaning solutions
Sanitizers and detergents
High-temperature food and pharma processing
Can this silicone be die-cut or provided with adhesive backing?
Yes — H-O Products supplies die-cut FDA gaskets, PSA-backed silicone sheets, strips, extrusions, and custom OEM sanitary components.
