    Precision Polymer EngineeringPrecision Polymer™ S71U
    • Polymer Name:Silicone Elastomer
    • End Uses:Food Packaging, Food Preparation Equipment, Gaskets, O Rings, Medical Pump Seals, Medical/Healthcare Applications, Potable Water Applications, Non Specific Food Applications, Valve Seats
    • Features:Good Surface Finish, Low Taste Transfer, High Purity, Good Sterilizability, Non-Toxic, Autoclaved, No Animal Derived Components, Low Odor, Food Contact Acceptable
    S71U is a high transparency grade of silicone rubber intended for use in food, dairy, brewing, potable water, pharmaceutical and biomedical applications. Platinum-cured silicone is odorless, tasteless and non toxic. Seals made from S71U are resistant to repeated sterilizing, autoclaving and cleaning agents commonly used in these industries.Unlike traditional peroxide-cure methods, platinum curing results in a smooth contact surface finish and a high degree of purity. No residue substances such as benzoic acid, peroxides, ketones are produced during manufacturing, which can be transferred from the seal to critical hygienic products.Key Attributes Compliant with FDA FDA CFR210177.2600 for use with dry, aqueous and fatty food stuffs. Conforms to USP class VI suffix 87 and 88, Biological Reactivity tests. Good mechanical and physical properties Chemically stable over a temperature range of -60°C to +200°C. Withstands sterilizing and autoclaving procedures Free from Animal Derived Ingredients (ADI) Typical Applications Food processing and packaging equipment Pharmaceutical and biomedical apparatus Hygienic seals in dairy equipment Potable and high-purity water applications

    • Applications:Equipment & Parts, Cooling & Climate, Appliances & Electronics
    • Product Families:Other Thermoset Elastomers, Thermoset Elastomers
    • Polymer Name:Synthetic Rubber (unspecified)
    • End Uses:Food Preparation Equipment, Industrial Applications, Non Specific Food Applications
    Addisil™ 2070 E series is a two-component heat curable rubber for making elastomers (HCE) with a hardness range between 50 and 80 Shore A for industrial applications. This series is based on a platinum cure system, which is particularly suitable for high value extrusion applications where regulatory compliance, transparency, mechanical performance and/or productivity are important. Application examples are oven door profiles and tubing for food applications.Key Features and Benefits Good transparency, no yellowing Good mechanical performance Dry, non-stick surface Odorless during processing and in its application Fast curing Long shelf life of 6 months for the single components if stored appropriatelyM Very long pot life of 2 to 4 weeks for the mixed components Suitable for compliance with the food contact regulations FDA 21 CFR 177.2600 and the BfR section XV recommendations KTW: German Water Regulation. A representative sample has passed the test for tubes, fittings, seals and strorage systems (cold and warm) WRAS (BS 6920). A representative sample has passed the test (cold and warm) W270: Microbiological growth test. A representative sample has passed the test.
