80 Durometer FDA Grade Solid Silicone — Technical Overview & FAQs
Product Overview
80 Durometer FDA Grade Solid Silicone Rubber is an extra-firm, platinum-cured silicone elastomer engineered for high-pressure sanitary sealing, food-contact safety, and maximum mechanical stability.
Fully compliant with FDA 21 CFR 177.2600, this material is odorless, tasteless, non-toxic, and suitable for demanding food, beverage, pharmaceutical, and sanitary processing environments.
At 80 Shore A, this is one of the firmest FDA silicone rubber grades available, offering extremely low compression under load, exceptional dimensional stability, and superior durability in continuous high-temperature or chemically intense environments.
This material is ideal for applications requiring structural sealing support, high clamping loads, and long-term performance in hygienic or FDA-regulated systems.
Applications
High-pressure sanitary gaskets
Food-processing equipment seals
Pharmaceutical and bioprocessing systems
Rigid enclosure seals for hygienic machinery
High-temperature sealing in ovens, heaters, and cooking equipment
FDA-compliant die-cut gaskets, sheets, strips, and extruded shapes

FAQs
What is 80 Durometer FDA Grade Silicone used for?
It is used for high-pressure sanitary seals, food-processing and beverage equipment, pharmaceutical systems, and industrial hygienic sealing requiring maximum firmness and structural stability.
Is 80 durometer silicone safe for food-contact applications?
Yes — it meets FDA 21 CFR 177.2600, making it safe for incidental food contact in sanitary systems, food equipment, and pharmaceutical environments.
How firm is 80 durometer FDA silicone compared to other grades?
80A silicone is extremely firm, offering:
Minimal compression
High sealing pressure
Superior mechanical durability
Maximum stability under heavy clamping loads
It is firmer than 50A, 60A, and 70A FDA grades.
Can 80 durometer silicone withstand steam, hot water, and sanitation cycles?
Yes — it withstands long-term exposure to:
Steam
CIP cleaning chemicals
Detergents and sanitizers
Hot water washdowns
High-temperature operating conditions (up to 450 °F)
