Abstract: 1305893 Curing rubber DEFENCE SECRETARY OF STATE FOR 4 March 1970 [5 Dec 1968] 57747/68 Headings C3E C3P and C3T A rubber or elastomer is cured by a process including a first step of introducing cross-links into the rubber or elastomer when it is in an unstressed condition and a second step of introducing further cross-links into the rubber or elastomer when it is held under a compression in a single direction greater than any compression applied, during the introduction of the cross-links in the first step. Both steps may be carried out during normal cure of the rubber or elastomer, or in a post-curing stage, or the first step may be a normal cure and the second step a post-cure. The process may be applied for the curing of a silicone rubber using a peroxide curing agent, different peroxides being used in the first and second steps, if desired. In examples : (a) a vinylidene fluoride copolymer elastomer is cured by use of dicinnamylidene- 1,6 - hexanediamine, triethylene tetramine (TETA) or TETA and p-phenylene diamine, post-cured in unstressed state and then postcured at 25% compression in air and (b) compounded natural rubber or butadiene-styrene rubber is press-cured and post-cured at 25% compression.
