Analytic function of automotive door seals

Used to maintain the body seal doors, windows and other movable portion, and front and rear window, a triangular window, which do not seal the movable portion, the sealing strip should be adapted to the shape of the section of the use of different parts and different functionality.container security seals

The purpose of the sealing strip:

① keep the car to avoid the rain, dust, heat and sound insulation;

② When the body is subjected to vibrations with a twist, the seal also play a buffer, absorbing, maintaining the role of the glass;

③ on the edge of the transfer windows for decoration;

Seal material, early often use natural rubber, later developed into an ethylene, propylene rubber, nitrile rubber, synthetic rubber as the mainstream, there is also polyvinyl chloride resin. For the former, rear window, triangular windows and other fixed window edge portion, there is also a variety of adhesive forms (such as direct bonding method or rubber band bonding method).

As a synthetic rubber foam should have a good performance, which requires:

Excellent weather resistance;

For coating with a non-polluting;

Small residual deformation;

Low water absorption;

At low temperatures can maintain good flexibility;

Heat resistance;

Good wear resistance.padlock seal

Door seal with the body is a more difficult position, sealing requirements more stringent, should be sealed part of the long, cross-sectional shape of the sealing parts are not the same, but the doors open and close frequently.

Door seal to achieve the basic cross-sectional shape in three ways: bending type, compression type, complex. And different parts of the seal practical shape is more complex.
