Application of Environmentally Friendly Accelerator Vultac TB710 in EPDM

TAO Ping;WANG Liangyan;ZOU Huifang;WANG Dingdong;Nanjing Lide Oriental Rubber & Plastic Technology Co.,Ltd;  
The application of accelerator Vultac TB710(sulfur donor) which did not produce nitrosamines in EPDM compound was studied. The results showed that,when accelerator Vultac TB710 replaced accelerator TMTD-80,DPTT-75,or DTDM-80 in the compound,the vulcanization speed of the compound slowed down,and the tensile strength,elongation at break and compression set increased. When the dosage of accelerator Vultac TB710 increased,the vulcanization speed of the compound increased. The active component of accelerator Vultac TB710,alkylphenol disulfide,decomposed during the vulcanization and produced alkylphenol free radicals or alkyl sulfide free radicals which possessed similar structural features as hindered phenol antioxidants and provided protection against thermal oxidative aging.
