| Abstract: |
| The effect of the primary flame retardant magnesium hydroxide [Mg(OH)2] combined with decabromo diphenylethane(DBDPE)/antimonous oxide(Sb2O3)/ingredient A——a polymerized organo-silicone on the properties of EPDM/PP TPV was investigated.The results showed that the physical properties of EPDM/PP TPV would decrease by adding Mg(OH)2；the flame retardance of EPDM/PP TPV improved significantly by using Mg(OH)2 combined with DBDPE and Sb2O3，and the physical properties and rheological properties changed little；and the oxidative index of EPDM/PP TPV increased remarkably and the rheological properties improved by adding ingredient A，but the physical properties decreased.The optimized flame-retardant formula of EPDM/PP TPV was as follows：EPDM/PP TPV 100，Mg(OH)2 50，DBDPE 20，Sb2O3 7，ingredient A 5. |
