OBC3725 is easy to be processed, and its performance exceeds that of POE, EPDM, EVA, SBC and other polyolefin plastic bodies with excellent processing performance, and the introduction of a certain amount of octene weakens the crystallization of polyethylene segment, forming an unshaped region (rubber phase) with rubber elasticity. OBC3725 has excellent high elasticity, high toughness and good low temperature performance. In addition, its molecular chain is saturated and contains relatively few tertiary carbon atoms, and its narrow relative molecular mass distribution makes it difficult for the material to shrink and flex during foaming, injection and extrusion processing. The polymer has a narrow molecular weight distribution, a well-structured short branched chain, and a limited number of long branched chains, which endowing OBC 3725 with the characteristics of easy processing. Its performance exceeds POE, EPDM, EVA, SBC, etc.
