| Abstract: | Room temperature curing silicone rubber foam materials were prepared by using four liquid silicone rubbers(107 silicone rubbers) with different molecular weights as raw rubbers.The influences of rubber viscosity on the curing rate,that of molecular weights of the raw rubbers on the hole morphology,mechanical properties and thermal stability of the silicone foam were investigated.The results indicated that the gelation and curing times of the silicone rubber were shortened with the increasing of viscosity of... |
