In building materials, sealant strips are often ignored due to their low cost, and are often ignored by the traditional concept of not paying attention to energy-saving standards for doors and windows. However, sealant strips play a vital role in building sealing and energy conservation. A key part of building energy efficiency. In particular, EPDM sealing tape, due to its excellent performance, is widely used in the field of building curtain walls, doors and windows, and plays a key role in building energy conservation.How durable is EPDM tape? In many cases, other adhesive strips simply cannot be held!1. Anti-aging: Due to the lack of polarity and low unsaturation of ethylene-propylene rubber, it is suitable for various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones and greases. Good resistance.2. Water vapor resistance: EPDM tape has excellent water vapor resistance and better than its heat resistance. In 230°C superheated steam, there is no change in appearance after nearly 100 hours.3. Superheated water resistance: EPDM rubber strips are also resistant to superheated water, but they are closely related to the vulcanization system used. The ethylene-propylene rubber strip with dithiodimorpholine and TMTD as the vulcanization system, after being immersed in 125℃ superheated water for 15 months, the mechanical properties change little, and the volume expansion rate is only 0.3%.4. Elasticity: There are no polar substituents in the molecular structure of EPDM strips, and the cohesive energy of the molecule is low. The molecular chain can maintain flexibility in a wide range, second only to natural rubber and butadiene rubber, and remains at low temperatures. Long-term use can maintain good firmness and tightness, and can effectively achieve sound insulation and dustproof performance.5. Anti-ultraviolet and radiation: EPDM tape can provide environmental protection for residents of high-rise buildings. Withstand voltage 60-150KV, resistant to corona, electric crack, and arc. Low temperature elasticity, when the stretching capacity reaches 100MPA, the temperature is -58.8 degrees Celsius.
