Foamed silicone sealing strip is widely used in automobile, aerospace, computer, mechanical and electrical industry, dust removal equipment, dust removal equipment, cement plant cover plate, mining equipment, door seal, fax machine, printer high temperature parts; automobile machinery body, kitchen appliances, household appliances and other equipment. The performance of the foamed silicone sealing strip is: good thermal stability. Excellent aging resistance-can be used for a long time at 130°C, and can also be used at intervals or for a short time at 150°C or higher. The weather resistance of foaming silicone sealing strip refers to the aging of light, heat, freezing, wind, rain, ozone and oxygen in the atmosphere in the natural environment. Chemical resistance: Due to the chemical stability and non-polarity of the foamed silicone seal, it does not react with most chemical substances, and is insoluble or insoluble with polar substances. Resistant to alcohol, acids (formic acid, acetic acid), strong bases, oxidants (such as H202, HClO, etc.), detergents, animal and vegetable oils, ketones, some lipids, hydrazine. Three. Excellent water resistance, resistance to overheating and water vapor resistance: water is a strong polar material, EPDM is a polymer chain hydrazine, with "hydrophobicity". It is not easy to produce chemical interaction between them, so it has excellent water resistance, overheating resistance and water vapor resistance.
