Compliance
- FDA 21 CFR 177.2600 — Compliant (Pass)
- Soft food contact gaskets and seals in dairy and high food contact processing equipment
- Die-cut sealing components for FDA-regulated environments where visual inspection of seals is required
- Seals and gaskets in applications requiring odorless, tasteless, and non-yellowing materials
- Flexible sealing elements in food contact assemblies with moderate conformability requirements
- General-purpose food-grade seals across a broad thermal service range
Common industries: Dairy processing, food processing, food service equipment, pharmaceutical, beverage equipment.
30 Durometer Translucent FDA Grade Solid Silicone is a soft translucent FDA grade solid silicone sheeting at 30 Shore A, formulated for food contact and dairy sealing environments where high compliance and visual cleanliness are required. Its translucent appearance, combined with odorless and tasteless properties and freedom from yellowing, makes it well suited for dairy processing, beverage, and food service gasket applications where contamination detection and hygiene are paramount.
The material provides 800% elongation and a specific gravity of 1.06 g/cc, indicating a highly flexible, lightweight compound. It exhibits excellent UV and ozone resistance and functions as an effective electrical insulator. The sheeting is readily die-cut into precision seal and gasket profiles.
Compliant with FDA 21 CFR 177.2600 — Pass.
What differentiates 30 Durometer Translucent FDA Grade Solid Silicone from softer and firmer translucent FDA grades in this series?
30 Durometer Translucent FDA Grade Solid Silicone provides a soft 30 Shore A profile with 800% elongation, positioned above the 20-durometer grade in firmness while remaining highly compliant. It is appropriate for food contact sealing applications where moderate flexibility is needed alongside the hygienic and visual properties of a translucent, odorless, tasteless silicone.
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 30 Durometer Translucent FDA Grade Solid Silicone?
30 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 30 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 30 Durometer Translucent FDA Grade Solid Silicone be specified?
Specify grade (30 Durometer Translucent FDA Grade Solid Silicone), thickness, compliance requirements, dimensional tolerances, and finished format.
