    Ozone and Weather Resistance Food Grade Red Silicone Rubber O Ring Seals

     

    The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicone elastomers as a group have relatively low tensile strength, poor tear and wear resistance. However, they have many useful properties as well. Silicone materials have good heat resistance and good cold flexibility. They also have good ozone and weather resistance as well as good insulating and physiologically neutral properties.

     

    Names: Silicone, VMQ

     

    Both o-rings and gaskets can be made from silicone materials.

    Ozone, aging, and weather resistant

     

    Description: A group of elastomers, made from silicon, oxygen, and hydrogen, Silicones are renowned for their retention of flexibility and low compression set characteristics, within one of the widest working temperature ranges for elastomers.

     

    Key Use(s): Static seals in extreme temperature situations. Seals for medical devices, compatible with FDA regulations.

     

    Temperature Range:
    Standard Compound: -85° to +400°F

    Hardness (Shore A): 40 to 80

     

    Features: Phenyl (PVMQ) based silicones can perform to -85°F. New polymers can take short term to 600°F.

     

    Limitations: Generally, low abrasion and tear resistance, and high friction characteristics preclude silicones from effectively sealing some dynamic applications. Silicones are also highly permeable to gases and are generally not recommended for exposure to ketones (MEK,acetone) or concentrated acids.

     

    In the Silicone family, you will find compounds which are superior as static seals in extreme temperature conditions. Standard compounds handle operating temperatures -85º to +400ºF. Silicone compounds are popular in food and medical applications because they are very clean and do not impart odor or taste. Special Phenyl silicones can be used down to -148°F.
