20 Durometer Translucent FDA Grade Solid Silicone
20 Durometer Translucent FDA Grade Solid Silicone is a translucent FDA grade solid silicone sheeting rated at 20 Shore A — the softest and most compliant grade in the translucent FDA silicone series — designed for high food contact and dairy applications. It is easily die-cut and provides a highly flexible gasket and sealing solution across a continuous service range of -80°F to 450°F, with intermittent capability to 500°F. The material passes FDA 21 CFR 177.2600 and is odorless, tasteless, and non-yellowing.

Compliance
- FDA 21 CFR 177.2600 — Compliant (Pass)
- Ultra-soft food contact gaskets and seals in dairy and high food contact processing equipment
- Die-cut sealing components requiring maximum flexibility and FDA compliance
- Seals and gaskets in applications where odorless, tasteless, and visually clean materials are required
- Flexible sealing elements in food contact assemblies requiring very low closure force
- General-purpose food-grade seals across a broad thermal service range
Common industries: Dairy processing, food processing, food service equipment, pharmaceutical, beverage equipment.
20 Durometer Translucent FDA Grade Solid Silicone is the softest grade in the translucent FDA silicone sheeting series at 20 Shore A, providing maximum flexibility and conformability for food contact and dairy sealing applications. Its 20 Shore A hardness and 1200% elongation — the highest in the translucent FDA series — make it appropriate where extremely low sealing force or highly deformable gasket geometry is required.
The translucent appearance, combined with its odorless and tasteless nature, suits it for dairy and high food contact environments where visual cleanliness and absence of taste or odor transfer are priorities.
The material exhibits excellent UV and ozone resistance and functions as an effective electrical insulator. It passes FDA 21 CFR 177.2600 and is formulated from high-quality raw materials. The sheeting is readily processed by die-cutting.
Compliant with FDA 21 CFR 177.2600 — Pass.
What differentiates 20 Durometer Translucent FDA Grade Solid Silicone from higher-durometer translucent FDA grades in this series?
20 Durometer Translucent FDA Grade Solid Silicone is the softest and most compliant grade in the translucent FDA silicone series at 20 Shore A, with the highest elongation (1200%) and lowest specific gravity (1.05 g/cc) in the lineup. It is the appropriate choice when maximum softness and conformability are required in food contact or dairy sealing applications.
Why is compression set an important consideration for solid silicone elastomers?
Compression set measures how well an elastomer recovers its original thickness after sustained compression. In sealing applications, a material with high compression set will permanently deform over time, reducing sealing force and allowing leak paths to develop. Low compression set is listed as a key feature of this material, indicating it is formulated to maintain sealing integrity over extended service periods.
What is the service temperature range for 20 Durometer Translucent FDA Grade Solid Silicone?
20 Durometer Translucent FDA Grade Solid Silicone is rated for continuous service from -80°F to 450°F, with a high intermittent temperature resistance of 500°F, as listed on the TDS.
Is 20 Durometer Translucent FDA Grade Solid Silicone suitable for food contact and dairy environments?
Yes. This material passes FDA 21 CFR 177.2600 and is specifically designed for high food contact and dairy applications. It is odorless, tasteless, and non-yellowing, as stated on the TDS.
How should 20 Durometer Translucent FDA Grade Solid Silicone be specified?
Specify grade (20 Durometer Translucent FDA Grade Solid Silicone), thickness, compliance requirements, dimensional tolerances, and finished format.
