    Soft Silicone 40 Rubber Sheet

    Reglin Soft Silicone 40 Rubber Sheet is a premium grade 40 Duro food grade and heat resistant silicone rubber sheet.


    Soft Silicone 40 Rubber Sheet is softer than standard Silicone.  It is highly flexible and compressible and has excellent sealing capabilities.  It has very high temperature resistance and will maintain its flexibility and physical properties over a wide temperature range.   Silicone has excellent ozone resistance and is UV stable making it weather resistant and suitable for outdoor use.

    Reglin Silicone 40 Rubber Sheet is tested and conforms to FDA 21 CFR 177.2600 “Rubber articles intended for repeated use”.  This makes it suitable for contact with dry, aqueous and fatty foods as defined by the FDA

    Silicone 40 Rubber Sheet is fully post cured.  It is carefully produced to comply with European Commission regulations EC2023/2006 “good manufacturing practise for materials and articles intended to come into contact with food”.

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


    Reglin Silicone 40 Rubber Sheet conforms with the following standards.

    As stated in FDA CFR 21.177.2600.  In accordance with good manufacturing practise finished rubber articles intended for repeated use in contact with food shall be thoroughly cleansed prior to their first use in contact with food.
