HYDROGENATED PETROLEUM RESIN AND RUBBER COMPOSITION COMPRISING SAME
The present disclosure relates to a hydrogenated petroleum resin and a rubber composition including the same. The hydrogenated petroleum resin according to the present disclosure not only improves the viscoelastic properties of rubber containing the same, but also has excellent compatibility with rubber, thereby improving the overall physical properties of the rubber. Thus, rubber molded articles manufactured from the rubber composition containing the hydrogenated petroleum resin, for example, tires, have improved grip strength (wet/dry) and reduce an increase in rolling resistance due to the improvement in grip force to simultaneously satisfy two properties of grip force and rolling resistance required as a tire, thereby manufacturing a low-fuel consumption and high-performance tire.
Hot-melt pressure sensitive adhesive composition having improved rheological properties
An adhesive compositions containing at least one first styrene-isoprene-styrene block copolymer having a diblock content of not less than 45%, at least one second styrene-isoprene-styrene block copolymer having a styrene content of not more than 30 wt.-%, at least one first tackifying resin having a softening point of equal to or higher than 100° C., and at least one second tackifying resin having a softening point of equal to or higher than 120° C. Further, a method for bonding substrates together using the adhesive composition.
