Abstract：The effects of foaming agent,additive and curing agent content on tensile strength,rupture elon-gation and apparent density of foaming silicone were studied by the orthogonal experiment.The optimal for-mula for foaming silicone were 100 copies of base adhesives,3 copies of foaming agents,2 copies of addi-tives,and 2.5 copies of curing agents.The related mechanical properties and thermal properties of the above four formulae were investigated by scanning electron microscopy(SEM),multifunctional tensile ma-chine,and hot disc instrument.Results presented that the optimum formula had moderate mechanical prop-erties,well defined and dispersed inner pores,and desired thermal insulation performance.
