Door and window sealing strips are divided into three categories: glass sealing strips (rubber strips), door leaf sealing strips and wool strips,

The glass sealing strip is used for sealing between the glass and the leaf and the frame, the door leaf sealing strip is mainly used for sealing between the door panel and the door frame, and the wool strip is mainly used for sealing between the frame and the leaf.

In the production and installation of plastic steel doors and windows and broken bridge aluminum doors and windows, wooden doors, sealing strip is an essential accessory. It is mainly used for plastic steel doors and windows, broken bridge aluminum doors and windows and wooden doors to ensure the fastening of rubber strips and profiles.

The sealing strip needs to have strong tensile strength, good elasticity, and good high temperature resistance and aging resistance.

The functions of door and window sealing strips mainly include waterproof, sealing, energy saving, sound insulation, dustproof, antifreeze and heat preservation.

The door and window sealing strips on the market are generally extruded from PVC, modified PVC, EPDM, elastomer sealing strips (including TPV, TPE, TPR, SEBS), silicone and other materials.

EPDM rubber strip has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity and other physical and mechanical properties. These advantages are irreplaceable by other materials such as PVC.
