HX1689 series Hydrocarbon Resin (other name: Petroleum Resin)are widely used in Tire Rubber Compounding. The resins are well compatible with natural Rubber(NR), many kinds of synthetic rubber (including SBR, BR, CR, NBR, IIR and EPDM), Polyethylene, Polypropylene, SIS, SEBS, EVA as well as natural tackifier resins (such as terpene, colophony and its derivative). It has following features: Light color, excellent green tack, lowers mooney viscosity of compound, limited influence on vulcanization time and physical properties after vulcanization. It lowers hardness and modulus of compound after vulcanization and improves extension and chipping resistance performances. Help fillers distribute evenly, Avoid adhesion to compounding equipment.
