Both petroleum resin and rosin resin are one of the main raw materials in the adhesive field and are used in most adhesive products. The use of the two is generally similar. Let us look at the specific differences below.
The difference between petroleum resin and rosin resin in the adhesive field
In terms of performance, the initial viscosity of rosin resin is better, but petroleum resin also has better performance in aging resistance. In order to combine the advantages of both, many products are used together to neutralize the advantages of both, making product performance more perfect.
Rosin resin is used as a "tackifying resin" in the adhesive product to increase initial tack, improve wetting and plasticity, and promote mixing of the filler with the polymer.
Rosin resin has advantages over petroleum resin. Generally speaking, rosin resin has good initial tack and petroleum resin has good aging resistance. Moreover, while the technological process is further developed, the performance of petroleum resin in the initial viscosity is also gradually increasing, and the gap is gradually narrowed compared with the rosin resin.
