EPDM sealing strips for trains have excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical performance, oil filling and room temperature fluidity. EPDM adhesive strips can be used for a long time at 120 ℃, and can be used briefly or intermittently at 150-200 ℃. The use temperature can be increased by adding appropriate antioxidant, and EPDM crosslinked by peroxide can be used under harsh conditions. EPDM rubber foam strip has corrosion resistance. Due to the lack of polarity and low unsaturation of EPDM sealant strip, it has good resistance to various polar chemicals such as alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone and grease. EPDM rubber foam strip is usually used for sealing between the dust remover and dust collection cover plate of power plant.
