Features: 1. High degree of aging resistance. The sealing strip has strong aging resistance to heat-resistant air. It can be used at 100-120 degrees for a long time, and it can maintain effective physical properties for a long time at 140-150 degrees. It can withstand high temperatures of 230-260 degrees in a short time. 2. Superior weather resistance refers to light, heat, freezing, wind, rain, ozone in the atmosphere, and the aging of the final factors in the natural environment. It has long-term resistance to severe cold, heat, dryness and humidity. 3. Excellent oxygen resistance. , Ozone is the main factor of general rubber cracking. EPDM has excellent ozone resistance and is known as "crack-free rubber". Especially used in different atmospheric indexes, compared to rubber seals (PVC) It also shows the superiority of its products. It has a small shrinkage rate, no deformation, and can fully realize the common design life of doors, windows and curtain walls. 4. Excellent chemical resistance, due to the chemical stability and non-polarity of the EPDM strip itself. Therefore, it does not react with chemicals, and has little or no compatibility with polar substances.
