60 Durometer FDA Grade Solid Silicone is a medium-firm FDA grade solid silicone sheeting at 60 Shore A, designed for food contact environments where greater resistance to deformation under compressive load is required alongside regulatory compliance. Its 60 Shore A hardness and 1.42 g/cc specific gravity provide meaningful dimensional stability for food service gaskets, seals, and separators subject to sustained pressure. Compliance with FDA 21 CFR 177.2600 qualifies it for food processing and food service equipment applications.
The material provides 500% elongation, retaining useful flexibility for die-cut profiles. It exhibits excellent UV and ozone resistance and functions as an effective electrical insulator. Low compression set is cited as a key feature, supporting sustained sealing performance over time.
Compliant with FDA 21 CFR 177.2600 — Pass.
What differentiates 60 Durometer FDA Grade Solid Silicone from softer and firmer FDA grades in this series?
60 Durometer FDA Grade Solid Silicone provides a medium-firm 60 Shore A profile with a specific gravity of 1.42 g/cc, offering greater dimensional stability under compressive load than the 40 or 50 Shore A grades. This makes it the preferred choice in food contact applications where the gasket must resist creep or permanent deformation under sustained sealing pressure.
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 60 Durometer FDA Grade Solid Silicone?
60 Durometer 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 60 Durometer FDA Grade Solid Silicone suitable for food contact environments?
Yes. This material passes FDA 21 CFR 177.2600 and is specifically designed for food contact applications, as stated on the TDS.
How should 60 Durometer FDA Grade Solid Silicone be specified?
Specify grade (60 Durometer FDA Grade Solid Silicone), thickness, color (white standard; other colors by special request), compliance requirements, dimensional tolerances, and finished format.
