The sealing material has the characteristics of low specific gravity, less than 0.9, which saves the project cost. Environmental protection and energy saving, it can pass RoHS and reach testing to meet export environmental protection requirements. It has a bright appearance and can be made matte. Good weather resistance, aging resistance, anti-ultraviolet rays, good tensile strength, and good airtightness. The low temperature resistance range is -40-80℃, which can completely replace PVC sealing material.

Performance of elastomer TPE sealing strip material

What is the role of door and window sealing strips? Plastic steel doors and windows, broken bridge aluminum doors and windows, wooden doors and windows, and sealing tape have the functions of sound insulation, dustproof, antifreeze, and heat preservation, and play an important role in waterproofing, sealing, and energy saving. At present, the sealing strips for doors and windows mainly use PVC, EPDM, TPV, TPE, TPR, silica gel and other materials.

The use of TPE sealing material can prevent the door and window sealing strips from becoming hard and brittle, losing the original elasticity and sealing function, resulting in water leakage and ventilation.

Inferior door and window sealing strips contain many harmful substances (such as soluble cadmium, antimony, lead and other heavy metal carcinogens). The volatilization of these soluble harmful substances will seriously damage human health. After being exposed to the sun or high temperature, the sealing tape will become sticky and adhere to the car windows and glass. "Oil leakage" sometimes occurs, which not only pollutes doors and windows, but also affects the sealing function and aesthetics of doors and windows.

Application of TPE in door and window sealing strip industry

The elastomer TPE sealing material is usually Shore A, with a hardness of 60-70 and a specific gravity of 0.94. The extrusion temperature is usually set between 175 and 200 degrees. TPE sealing material has excellent colorability, flexibility, weather resistance, fatigue resistance and temperature resistance. It has excellent processing performance, no vulcanization, recyclable and low cost.
