BLOWING AGENT COMPOSITION |
摘要 |
A blowing agent composition, comprising: (i) azodicarbonamide; (ii) zinc oxide and/or zinc carbonate; and (iii) at least one member selected from the group consisting of zinc salts of C1-C6 organic acids, and C1-C6 organic carboxamides characterized by a high gas evolution rate. The blowing agent composition may be used in effective amounts in formulations containing a foamable polymer to yield an efficiently gas expanded polymeric composition upon exposure to heat. Suitable C1-C6 organic acids for said zinc salts include straight-chain carboxylic acids, and useful organic carboxamides include formamide. |
