The performance change of sealing strip in aging environment has a very important influence on the sealing performance of doors and Windows.In the process of practical use, the quality problems of sealing seals in building doors and Windows are mainly manifested in hardening, embrittlement, loss of elasticity and sealing function.Sunshine pollutes door window, affect the sealing function of door window and beautiful, or shrink inside short time or purify groove, fall off, lose its function.

These are due to the poor quality of sealing rubber, poor aging resistance, long-term exposure to the sun, rubber after aging become hard, lose elasticity, easy to fall off.Not only poor sealing, and make the glass loose safety hazard.The failure of the sealing strip will have a great negative impact on the performance of the window, including reducing the air tightness of the window, water tightness and thermal insulation performance.The seal strip must remain flexible throughout the life of the window and integrate with the window.

Nowadays, with the promotion of green and low-carbon buildings and the development of new high-tech materials, the i-eco enveloped seal strip has excellent comprehensive performance, which can meet various sealing requirements and maintain its physical and mechanical properties for a long time, enabling it to seal effectively for a long time.I - ECO doors and Windows sealing strip cladding type is coated by PE outside, high resilience PU foam as the main raw material, the enclosed PP matrix, so the sealing strip compression form, with about 10% of the following ensures that it can be applied in the doors and Windows, sealing strip cladding type sealing, PE coated outside largely increase the service life of the product, not only rich color is gorgeous, but also have more choices, the material of PP matrix of product also has very good fixed effect, can effectively prevent the product shrinkage after successful installation.

I-eco enveloped sealing strip is environmentally friendly and non-toxic, common epe sealing strip is not as long as its service life, after a system of research and testing found that the performance of enveloped sealing strip in long-term use of the discount rate is low, can play a long-term effect of sealing doors and Windows.
