Characteristics of EPDM sealing tape
Weather resistance: It has long-term resistance to severe cold, heat, dryness and humidity, and has good corrosion resistance to rain and snow erosion. Its shrinkage rate is small, and it is not deformed. It can completely achieve the same design as doors, windows and curtain walls. life. /Heat aging: It has strong heat-resistant air aging resistance. EPDM sealing strips can be used at 100-120℃ for a long time, and can maintain effective physical properties for a long time at 140-150℃, and can withstand high temperatures of 230-260℃ in a short time. Ozone resistance: Ozone is the main factor in general rubber cracking. Because EPDM has excellent ozone resistance, it is also known as "crack-free rubber", especially when it is used in different atmospheric indexes, it will show the superiority of its products compared to rubber-plastic sealing strip (PVC). EPDM is currently the world's recognized material for producing sealing products.
