Factory directly D Type Rubber Seal - Flocking Rubber Seal – Tianzheng

Product Introduction

Flocking rubbers’ main material is EPDM, the reason is EPDM rubber not only with good weather, UV, ozone resistance, but also with excellent high and low temperature resistance, so EPDM material widely used on automotive sealing system.

Flocking rubber in the automotive seal strip system occupies a very important position, the rubber flocking seal strip in addition to the basic seal and reduce wind noise, but also provides guide rail and support for glass lifting.

Auto flocking EPDM rubber seal strip are usually made of polyamide or polyester fiber wool, and sometimes are mixed with polyamide and polyester fiber. The length of villi is 0.5-0.8mm and most of the villi are black.

The flocking process mainly consists of pretreatment, gluing, electrostatic flocking and curing. After curing, the adhesive strip will clean up the surface floating villi, and then cut it at a specific size, put it into packing box, and check it for storage, delivery or further packaging.

Application

In cars, flocked rubbers are used for doors, sun roof- sand windows. Here, they perform a dual function: sealing with the body and the facilitation of opening and closing functions with a low degree of force. The technical advantages of flocking may be explained using the example of a car side window. The movement of a glass pane over a rubber profile requires the application of relatively high degree of force. In accordance with the friction law, the friction force measured here is described as the coefficient of friction. In the case of glass/rubber ,this is more than 1. Flocking the rubber may reduce the coefficient of friction to 0.25-0.3

The flocking of the vulcanized profile in continuous process is the most rational method. After extrusion, the profile is vulcanized in a UHF channel and hot air channel. The adhesive is then applied to the surface when it has cooled down to approximately 110`C and roughened. This is followed by flocking and then curing of the adhesive at approximately 170`C for 2-3 minutes.
