Composition of pressure sensitive tape

1.Pressure sensitive adhesive,

2.substrate

3.Primer

4.Back treatment agent

5.Isolation paper

The main components of the pressure sensitive adhesive and resin, including rubber such as polyacrylic acid ester or polyvinyl ether, homogeneous base material requirements, small scale and good to solvent invasive, including, (1) fabric such as cotton, glass cloth or nonwoven, etc., (2) the plastic films such as PE, PP, PVC and polyester film, (3) the paper such as kraft paper, glass transparent paper and so on, the base material The original degree is between 0.1-0.5mm.

The function of primer is to increase the adhesive strength between the adhesive and the base material, so that when the adhesive tape is removed, the adhesive tape will not be separated from the base material and sully the surface, and make the adhesive tape reusable. The commonly used primer is chloroprene rubber partially vulcanized with isocyanate, modified chlorinated rubber.

Backside treatment agents are usually prepared from materials such as polyacrylate,PVC, cellulose derivatives or silicone compounds. Can play the role of isolation agent. Double-sided adhesive tape with a layer of isolation paper such as semi-rigid PVC film,PP film or kraft paper.
