Sealing strip plays an important role on doors and windows
As the key material of energy saving safety door and window, sealing strip plays an important role in water tightness, air tightness and energy saving in doors and windows. Sealing Strip changes in various aging environment, and plays a very important in doors and windows. In practical application, the sealing strip quality problems building doors and windows in the main performance is to use soon as the key materials of energy security doors and windows, doors and windows in the sealing strip plays an important role in the water tightness and gas tightness and energy saving.
Sealing strip changes in various aging environment, for doors and windows sealing performance has a very important impact. In practical application, the sealing strip quality problems of building doors and windows in the main performance is going to be brittle and hard after a short use, losing their elasticity and sealing function. Or by sunlight, it sticks and attachment phenomenon on the form and glass, Making the doors and windows dirty and looks ugly. It effects the sealing function and doors or windows appearance. Or slot is contraction loss in short time. Losing all is because of the poor quality of rubber, aging resistance is poor, the long-term sun exposure and glue after aging hardening, loss of elasticity, easy to falling off. It cause not only poor sealing, but also cause loose glass, resulting in security risks.
The failure of the sealing strip will affect the performance of the window adversely, including reducing the air tightness, water tightness and thermal insulation of the window. The sealing strip must maintain flexibility in the window of the entire life cycle , and it will be need to be formed a whole with the window. Now people pay more and more attention to environmental protection, EPDM sealing strip, silicone seal sealing materials occupy a larger market.
