Abstract
A flexible material for thermal and acoustical insulation comprising an expanded polymer (blend) based on at least one elastomer, wherein expansion is achieved by decomposition of a mixture of at least two chemical blowing agents, comprising the exothermic chemical blowing agent 4,4'-Oxybis(benzenesulfonyl hydrazide) (OBSH) and at least one endothermic blowing agent.
