本研究主要在探討EPDM常用的架橋系統，以及硫磺/過氧化物並用的複合架橋系統，先以孟山都硫變儀(monsanto rheometer)來決定熱壓溫度，以及探討各架橋系統對於架橋速度的影響， 熱壓成型後試片，測試其機械特性及永久壓縮變形率，以老化試驗探討隨著硫化劑的比例不同對於耐老化程度的影響，以DMA進行分子鏈運動分析。
結果顯示硫磺(Sulfur)與過氧化物(DCP)以3:7比例並用的複合架橋體系，其硫化速度快且加工安全性好，機械性質與硫磺架橋體系統相當，且耐老化程度與永久壓縮變形率與過氧化物架橋系統相當，具有最好的綜合性能。

This study is focused on the common crosslinking system for EPDM rubber and a composite crosslinking system of sulfur / peroxide for EPDM rubber, A Monsanto rheometer was employed to determine the processing time and the optimum process temperature, and explore the crosslinking rate, and test the mechanical properties and compression set, Aging tests was used for investigating different proportions of crosslinking agent for heat aging resistance properties, The dynamic mechanical analysis (DMA) was used for investigating chain motion.
The experimental results show that the crosslinking system with sulfur and DCP in a weight ratio of 3:7，Yielded the faster crosslinking rate and the processing is safety, The mechanical properties is close to those with sulfur crosslinking system, the degree of resistance to aging and compression set were close to those of peroxide crosslinking system, had perfectly total properties .
