How to design the formula of the mixed silicone rubber?
A silicone tube formula for mixing rubber plastic 0.35 degrees above, vulcanized rubber hardness reached more than 85, but sulfur not more than 3, such a formula how to design? The requirement for the degree of plasticity in order to facilitate molding operation, the hardness is required to protect, the other is not required.
Shenzhen Qiyu silicone rubber manufacturers share: filling cannot be, resin hardening, and high benzene styrene butadiene rubber filled with silica, s using the 1.6PHR, hardness is about up to 90a. But I did not measure the mixing degree of plasticity is how much? Requirements of the degree of plasticity, is because this product in production need a film. The film thickness should be about 2mm, and then the legitimate molding paste, if the degree of plasticity is too low, the operation is more difficult. Requirements of the degree of plasticity, with the use of the curing reaction process additives, resin, thickening of hardening agent. Because of the rollers to do it, I have a formula is Mooney value of 30 and 95 hardness of EPDM rubber formulation, washback elastic 45%, tensile strength of 20 MPa formula. Hardness of high styrene weight a little more naturally high. Should be able to do so, process and the curing characteristics of the balance.
