Rosin resin and petroleum resin are one of the main raw materials in the field of adhesive bonding.
The two applications are similar in general, the performance analysis, rosin resin initial viscosity is better, and the aging resistance of petroleum resin has better performance.
Therefore, many products are the use of the two together, can neutralize the advantages of both, so that the product performance is more perfect.
However, rosin resin is mainly made from natural resources and has the benefits of a recyclable economy and sustainable supply.
Many hot melt adhesive manufacturers are increasingly turning to rosin because of fears of oil scarcity and concerns about the human environment.
Of course, pine resin is a good choice in this respect.
We predict that in the next few years, rosin resin will replace more petroleum resin.
By 2015, rosin resin will account for more than 30% of the total global demand for hot melt adhesive to viscosified resin, and the demand will exceed 280,000 tons.
Rosin resin is used as a "viscosifying resin" in adhesive products to increase initial viscosity, improve wettability and plasticity, and promote filler and polymer mixing.
As mentioned above, compared with petroleum resin, both have advantages. Generally speaking, rosin resin has good initial viscosity and good aging resistance.
Moreover, with the further development of technology and technology, rosin resin in the aging resistance performance is also gradually improved, compared with petroleum resin gap is not big.
