Door and window sealing strips are the most common sealing products. Their function is to seal and waterproof. The door and window sealing strips that are exposed outdoors for a long time must have the characteristics of heat resistance in summer and cold resistance in winter. At this time, in order to reduce raw material costs and ensure the quality of sealing strips, three Yuan ethylene and propylene reclaimed rubber has become the best raw material choice.
Door and window sealing strip FAQ: After the winter sealing strip is used, it will become hard and brittle and lose its elasticity, which will affect the sealing effect and cause the shrinkage groove to fall off in a short time; the sealing strip will become soft under strong sunlight. The performance of EPDM reclaimed rubber can just make up for the insufficiency of the performance of the door and window sealing strips. In both the cold winter and the hot summer, the sealing strips maintain good performance.
1, EPDM reclaimed rubber is resistant to high and low temperature, can ease the sealing strip in the winter, become hard and brittle, loses elasticity, affects the use effect, softens the stickiness in the summer, affects the aesthetic problems, and prolongs the service life of the door and window sealing strip;
2, EPDM reclaimed rubber has good UV resistance and weather resistance, which can reduce the effect of UV and seasonal changes on the performance of the door and window sealing strip, and ensure the sealing effect of the sealing strip in the use cycle;
3, EPDM reclaimed rubber is the best renewable rubber anti-aging properties, has a strong resistance to harsh environments, can delay the aging of door and window weatherstrips, to ensure that the service life of windows and doors sealed doors and windows synchronization.
In summary, EPDM reclaimed rubber has become the most suitable reclaimed rubber product for door and window sealing strips due to its superior resistance to high and low temperatures, UV resistance, and aging resistance. In a variety of harsh environments, the use of EPDM reclaimed rubber door and window seals can maintain its performance does not change, in the service life for a long time with good sealing effect, thermal insulation, wind effect.
Some people think that EPDM reclaimed rubber is used as a product of waste rubber recycling and reprocessing, and lost most of its performance characteristics in the production process. It cannot guarantee product quality in the production of door and window sealing strips, but Xiao Bian wants to say: The EPDM reclaimed rubber can be comparable to the EPDM rubber, and the price is much lower than that of the original rubber. A good product plus a reasonable formula can fully meet the performance requirements of the door and window sealing strips. Door and window seals allow users to judge the quality of seals by observing their color and smell.
