What are the differences in the properties of petroleum resins and rosin resins in adhesive bonding?
However, the main material of rosin resin comes from natural resources and has the advantages of recyclable economy and sustainable supply. Many manufacturers of hot melt adhesives are increasingly turning to rosin resins for fear of lack of oil and concern for the human environment. Of course, in this regard, pine resin is a good choice.
We predict that rosin resin will replace petroleum resin more in the next few years. By 2015, the proportion of rosin resin will reach more than 30%, and the demand will exceed 280 thousand tons.Rosin resin is used as a tackifier in adhesive products to increase initial adhesion, improve wettability and plasticity, and promote mixing of fillers and polymers. As mentioned above, compared with petroleum resin, both have their own advantages. Generally speaking, the initial viscosity of rosin resin is good, and the aging resistance of petroleum resin is good. Moreover, in the further development of technology and technology, the performance of rosin resin in the aging resistance is also gradually improved, and compared with the oil resin, the gap is not big.
Rosin resin and petroleum resin are one of the main raw materials in the adhesive bonding field, which are used in most adhesive products.The use of both is roughly similar, performance analysis, the initial viscosity of rosin resin better, and the aging resistance of petroleum resin also has better performance. Therefore, many products are used together, which can neutralize the advantages of both, so that the product performance is more perfect.
