| Abstract: | The effects of peroxides,sulfur donor and complex curing systems on the properties of halogen free flame retardant EPDM were investigated.The result showed that the halogen-free flame retardant EPDM having excellent properties was prepared by using peroxides,sulfur donor and complex curing systems.The scorch time was 65s,the curing time was 478s,the tensile strength was 13.2MPa,the tear strength was 29.4 kN/m,the Shore A hardness was 68 points;The retention of tensile strengthe and retention of elongation at break were more than 90%;The vertical burning of EPDM reached level FV-0.Its electrical insulation property was also fine. |
