Factory direct sales of special seals for security doors, security door rubber strips

The wrapped sealing strip has achieved excellent results beyond all traditional products in tests such as aging resistance, fatigue resistance, compression deformation test, compression force test, thermal conductivity value test, water intrusion, and water permeability. At the same time, the wrapped sealing strip has Energy saving and environmental protection, sound insulation and noise reduction, strong ultraviolet resistance, non-toxic, non-reactive with any paint or detergent, catering to the green and healthy theme of the new era.
The wrapped sealing strip has excellent adhesion effect on metal doors such as security doors, copper doors, and stainless steel doors. It can adapt to changes in outdoor temperatures in four seasons. It can not only save production efficiency during operation and installation, but also It is even more convenient and feasible.
The unique door design can effectively solve the common problem of reduced or even failure of door sealing effect due to deformation and sinking of wooden doors after long-term use.
The relevant technical parameters of the covered sealing strip are provided below for confirmation by customers from all walks of life

Compression deformation test


At ℃, the compression rate continues When compression is small, deformation rate


, compression force test

At a compression rate of , apply / force, compression rate.


, Temperature range test

From ℃ to ℃, the sealing performance has no obvious change. The conduction value test value is / at ℃.


, Thermal conductivity value test


The value at ℃ /.


Fatigue resistance test

There is no obvious change in the shape after simulating the window switch tens of thousands of times.


, Sound insulation test

Noise reduction scores for windows with only middle strips and for windows with middle strips and additional strips.


, Outdoor Aging Resistance Test

At present, the performance has been maintained for more than 10 years. Product Features: Advanced engineering polyethylene outer film, good paint resistance and Migration resistance and attractive appearance.
