The ratio of the cure rate to the cure speed: CR = 100 / (tc90-ts2)
In essence, the cure rate measures the ascending curve’s linear slope.
Curing speed is the rate of crosslinking and the development of the compound’s stiffness (modulus) after the point burnt (ts5). Beyond this temperature, the compound begins to transition from a soft plastic to an elastic, resilient substance.
The bonds that bind the lengthy polymer chains to one another are created during the curing step. The polymer chains join more tightly as more bonds are formed, and the compound becomes stiffer (modulus) as a result.
Curing speed is a crucial vulcanization characteristic since it controls the amount of time needed to produce the crosslink or cure time.
