SIL silicone rubber O ring:
Excellent heat resistance, cold resistance, ozone resistance, resistance to atmospheric aging. Have very good insulation performance. But the tensile strength is lower than that of general rubber and is not oil resistant.
Suitable for household appliances such as electric water heater, electric iron, microwave oven, etc.. It also applies to all kinds of products which have contact with the human body, such as water bottles, drinking fountains, etc.. Is not recommended for use in most concentrated solvents, oils, concentrated acids and sodium hydroxide. General temperature range is -55~250.
VITON fluorine rubber O type ring:
High temperature resistance is better than silicone rubber, has excellent weather resistance, ozone resistance and chemical resistance, cold resistance is poor. For most of the oils and solvents are resistant, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils.
Sealing requirements for diesel engines, fuel systems and chemical plants. Do not recommend the use of low molecular weight in ketones, esters and mixtures containing nitrate. General temperature range is -20~250. (Note: oil resistant, acid and alkali resistance, no)
FLS silicone rubber O ring: the advantages of both performance fluorine rubber and silicone rubber, oil resistance, solvent resistance, fuel oil and high and low temperature resistance are good. Erosion resistance and oxygen containing compounds containing aromatic solvent and chlorinated solvent.
Generally used in aviation, aerospace and military applications. Not recommended for exposure to ketones and brake oil. General temperature range is -50~200.
EPDM three EPDM rubber O ring:
Has good weather resistance, ozone resistance, water resistance and chemical resistance. Can be used for alcohols and ketones, also can be used for sealing high temperature water vapor environment.
Suitable for sanitary and bathroom equipment, automobile radiator and automobile brake system. Not recommended for food use or exposure to mineral oil. General temperature range is -55~150. (Note: no oil, no acid resistance, alkali resistance)
