Tear Resistance Resin 101
Mixture of modified rosin and aliphatic resin
Light yellow granules
75 - 95
1 - 3
Increase the tackiness of NR and synthetic rubber, improve filler dispersion,processing property, tear strength of vulcanized rubber and anti-cutting performance.
Wet-skid Resistance Resin WSR1000
Mixture of modified rosin and aromatic resin
100 - 115
5 - 10
Contains polar and rigid groups and has good compatibility with rubber. Glass transition temperature of rubber compound moves to higher temperature, which improves the tanδ at 0℃ of the compound and grip performance.

Monomer polymerized petroleum resin
White block or granules
80 - 90
< 0.5 （125℃*3h）
Contains rigid groups and has good compatibility with rubber.
