| Abstract: |
| A optimized thermal-stable curing system has been found ro be used in production through the comparison among the thermal stabilities of EPDM vulcanizates cured with peroxide，sulfur，sulfur-containing compound and two different blend curing systems respectively.The vulcanizate cured with DCP features the excellent thermal stability，but lower tear strength and higher price.Thercfor the blend curing systems of DCP are adopted.The EPDM vulcanizate will show better thermal stabiliry when 5 phr of DCP and less than 1 phr of sulfur are used in The blend curing system. |
