In modern buildings, door frame universal sealing hard strip, as a key accessory, plays a vital role. It can not only effectively prevent the penetration of air, moisture and noise, but also improve the comfort and safety of the indoor environment. And all these excellent performances are largely due to the special materials used.Door frame universal sealing hard strip is usually made of high-quality plastic products. These plastic materials are carefully selected and specially treated to ensure their excellent durability and sealing performance. Among them, some common special materials include EPDM, silicone, PVC and thermoplastic elastomer (TPE).EPDM is a material with excellent weather resistance, high and low temperature resistance and corrosion resistance. It can maintain stable performance in harsh environments such as severe cold, heat, dryness and humidity, and is not easy to age, deform or crack. Therefore, EPDM sealing hard strips have been widely used in the field of doors and windows, and have become an important choice to ensure the sealing performance of door frames.Silicone is loved by users for its excellent elasticity and heat resistance. Silicone sealing strips have excellent plasticity and can adapt to various shapes of door frame gaps to ensure tight fit and sealing. At the same time, silicone is non-toxic, odorless, and environmentally friendly, which meets the modern people's pursuit of healthy life.PVC door frame sealing strips are widely favored for their stable performance and good material properties. PVC material has good weather resistance and corrosion resistance, and is not easy to yellow, deform or age. In addition, PVC sealing strips also have a high cost performance and are the first choice for many users.Thermoplastic elastomer (TPE), as a new type of polymer material, is also often used in the production of door frame sealing strips. TPE material has good elasticity, wear resistance and weather resistance, and can maintain stable performance during long-term use. At the same time, TPE material also has the characteristics of recyclability and environmental protection, which is in line with the concept of sustainable development.In summary, the special materials used in door frame universal sealing hard strips, such as EPDM, silicone, PVC and thermoplastic elastomers, all provide it with excellent durability and sealing performance. These materials not only ensure the stability and reliability of door frame sealing strips in various environments, but also improve the comfort and safety of the indoor environment. Therefore, when choosing door frame sealing strips, users should pay attention to the selection and quality of the materials to ensure the best sealing effect and user experience.
