摘要: Peroxide pre-vulcanized natural rubber latex prepared by using gamma irradiation technique is an alternative over the conventionally peroxide that used activator to promote decomposition in latex. Through this problems aroused some activators such as tends darken film during drying process can also be overcome. For preliminary study, data obtained from crosslink density and mechanical measurements were evaluate effectiveness of vulcanization process. Increasing quantity tert-butyl hydroperoxide (t-BHPO) 0.1 pphr 0.3 while dose maintain at 12 kGy has successfully delivered vulcanized films with average tensile strength, modulus @ 500% 700% around 15.33, 1.01 3.42 MPa, respectively. The effective pre-vulcanization respect maximum crosslinking (85.8 %) was observed on t-BHPO.
