Compliance
- FDA 21 CFR 177.2600 — Compliant (Pass)
- Food contact gaskets and seals in dairy and high food contact processing equipment requiring high tensile performance
- Die-cut sealing components for FDA-regulated environments balancing strength and flexibility
- Seals and gaskets demanding odorless, tasteless, non-yellowing, and visually inspectable properties
- Medium-soft sealing elements in food contact assemblies subject to sustained compressive load
- General-purpose food-grade seals across a broad thermal service range
Common industries: Dairy processing, food processing, food service equipment, pharmaceutical, beverage equipment.
50 Durometer Translucent FDA Grade Solid Silicone is a medium-soft translucent FDA grade solid silicone sheeting at 50 Shore A, combining high tensile strength (1200 psi) with exceptional elongation (900%) for demanding food contact and dairy sealing applications.
This grade provides a balance of physical robustness and compliance that suits it for gaskets and seals that must perform reliably under both mechanical stress and sustained compressive load in food processing environments. FDA 21 CFR 177.2600 compliance, combined with translucent appearance and odorless, tasteless, non-yellowing properties, supports use in hygienic and visually inspected food contact assemblies.
The material exhibits excellent UV and ozone resistance and functions as an effective electrical insulator. It is readily fabricated by die-cutting into precision seal and gasket profiles.
Compliant with FDA 21 CFR 177.2600 — Pass.
What differentiates 50 Durometer Translucent FDA Grade Solid Silicone from softer and firmer translucent FDA grades in this series?
50 Durometer Translucent FDA Grade Solid Silicone achieves 1200 psi tensile strength — among the highest in the translucent FDA series — while maintaining 900% elongation at a medium-soft 50 Shore A durometer. This profile is appropriate where food contact gaskets must deliver both high physical strength and substantial flexibility across a broad range of food processing conditions.
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 50 Durometer Translucent FDA Grade Solid Silicone?
50 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 50 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 50 Durometer Translucent FDA Grade Solid Silicone be specified?
Specify grade (50 Durometer Translucent FDA Grade Solid Silicone), thickness, compliance requirements, dimensional tolerances, and finished format.
