20 Durometer Translucent FDA Grade Solid Silicone — Technical Overview & FAQs
Product Overview
20 Durometer Translucent FDA Grade Solid Silicone Rubber is an ultra-soft, high-flexibility, platinum-cured silicone elastomer engineered for applications requiring exceptionally low compression force, gentle sealing, and food-contact safety.
Fully compliant with FDA 21 CFR 177.2600, this material is non-toxic, odorless, tasteless, and ideal for precision hygienic environments, delicate sealing interfaces, and applications requiring maximum softness.
At 20 Shore A, this is one of the softest FDA silicone grades available, providing outstanding elasticity, easy conformability, and excellent recovery—making it ideal for low-pressure gaskets, sanitary enclosures, sensitive medical equipment interfaces, and food- or beverage-processing components.
Applications
Ultra-soft sanitary and food-safe gaskets
Beverage processing and dispensing equipment
Delicate medical and laboratory device seals (non-implant)
Low-pressure sealing requiring minimal closure force
Soft cushioning pads for sanitary instrumentation
FDA-compliant extruded profiles and die-cut gaskets

FAQs
What is 20 Durometer Translucent FDA Silicone used for?
It is ideal for ultra-soft sanitary seals, food and beverage processing equipment, delicate medical devices, and low-pressure enclosures requiring very gentle sealing and high flexibility.
Why choose a 20A silicone over firmer FDA grades?
20A silicone provides maximum softness, making it perfect for:
Light-fastener applications
Sensitive equipment interfaces
Irregular sealing surfaces
Areas requiring very low compression force
Is this material safe for food-contact applications?
Yes — it complies with FDA 21 CFR 177.2600 and is suitable for incidental food-contact sealing in hygienic and processing environments.
Can 20 durometer silicone withstand high temperatures and cleaning chemicals?
Absolutely — it tolerates –80 °F to +450 °F, offering excellent resistance to:
CIP washdowns
Steam
Cleaning agents and sanitizers
High-heat food-processing environments
Can this material be die-cut or supplied with PSA backing?
Yes — H-O Products manufactures die-cut gaskets, PSA-backed silicone components, strips, extrusions, and custom OEM sanitary sealing solutions.
