    Soft Silicone 40 Rubber Sheet


    Reglin Soft Silicone 40 Rubber is a premium grade, non-toxic and inert 40 Duro Silicone Rubber Sheet, which has very high temperature resistance and is completely UV stable making it highly resistant to ozone effects and extreme weather conditions. Silicone rubber has good physical properties and will maintain its flexibility over a wide temperature range.

    Reglin Soft Silicone 40 Rubber Sheet is post cured, FDA compliant, per 21 CFR 177.2600, making it approved for repeated and long term contact with food and has WRAS approval, making it suitable for sensitive and critical high temperature sealing and protection applications.

    Silicone 40 Rubber Sheet has low thermal and electrical conductivity and high dielectric strength making it suitable for critical electrical and electronic insulating and isolating applications

    Silicone 40 is softer than standard Silicone 60 Rubber sheet making it suitable for sealing applications which require a highly flexible and compressible rubber.
