1. It is a kind of unmodifed resin reinforcing agent. When used together with methylenedonor, the reinforcing effect is remarkable after vulcanization of the compound, which can effectivelyimprove the modulus, hardness, tensile strength and tear resistance.

2. The reinforced resin can improve the processing, improve the plasticity of natural rubber various synthetic rubber and compound before vulcanization, so as to obtain better dispersion effect, and has the functions of plasticizer, tackifer and softener. After ulcanization in the laterstage, a dense network structure is formed, which plays an obvious reinforcing role for unmodifed materials.

3. The plasticizing effect of reinforced resin can be exerted when it is added in the early mixing stage, while the methylene donor is added in the late mixing stage, which can prolong the scorching time of the compound and improve the operation safety of the compound.

4. It can be used in various industries such as high-performance tires, rubber hose, conveyor belt, sole compound,sealing parts, etc.
