摘要

The polyolefin based polymer composition with high thermal coefficient reticulu00e1veis working in automotive cable and preparation process, a polymer composition and its preparation process,Comprising a mixture of polyolefins with high thermal coefficient reticulu00e1veis work in cable car.Characterized by a greater resistance to chemical attack of oils under high temperature of 150 u00b0 C, resistance to vertical flame propagation.And increase of resistance to abrasion by means of application of compound for insulation and coating of cables and electrical conductors.The polyolefins comprise a combination of chemical sinergistica between a load of halogenated hydrocarbons in combination with antimony trioxide, a alcoxisilano, a cross-linking agent.A combination of additives and auxiliaries of the process and a combination of all three antioxidants.
