Applications: As reinforcing agent for NR, SBR, BR, NBR, EPDM and CR, it is the main reinforcing agent for treads and sidewalls of tire , and for shoe-soles, window sealing strips of cars, rubber rollers,etc. As the same of normal reinforcing resin ,it can improve the hardness, tear resistance, abrasion resistance ,ensile strength, reduce the Mooney viscosity and prolong the scorch time. But compared with the unmodified resin, DHJH-E has the better compatibility in rubber ,so as to accelerate the dispersing of fillers and improve the processability. Specially, in the presence of saturated or unsaturated aliphatic hydrocarbons and carboxyls within DHJH-E, the hardness increasing rate of final products can be bigger about 5-10% than the one reinforced by the normal resin. To avoidprevulcanization, the resin should be added in early period, and the donors ,such as HMT or HMMM, should be added together with sulfur and accelerators as the last step in the mixing cycle. The reference dosage is 5-15%. |
