 ITEM  SPECIFICATIONS
 Appearance  Red brown flake or granule
 Softening point  90-100
 Ash %  0.5

Application:

       As reinforcing agent for NR, SBR, BR, NBR, EPDM and CR, it is the main reinforing 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 pocessability. Specially, in the presence of 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 avoid prevulcanization, 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 5-10%.

Package:

25kg paper bag.
