Silicone rubber sponge composition, method of making the sponge |
摘要 |
A sponge prepared from silicone rubber using 4,4'-oxybis(benzenesulfonhydrazide) as a blowing agent has improved heat stability when calcium oxide, magnesium oxide or a mixture of these two oxides is present in the composition. The sponge prepared using these oxides has a lower compression deflection after heat aging than the compositions which do not contain the oxides.
