Molecular formula : MW : CAS :
nature : Heating rubber oxidation of a malleable plastic refining process. General use ordinary SBR. First Cut small rubber, plastic or in refining tank, in about 150 ° C and pressure of compressed air 0.196 ~ 0.294 MPa (2 to 3 kilograms of force / cm 2) manner. Depending plasticity request. In order to make uniform quality, they often supplemented by mechanical processing. If there is heated in an inert gas or medium for thermoplastic necklace, the proceeds Kind of plasticity-low and unstable.
