NON-EXPANDING AGENT METHOD FOR PRODUCING FLAT-SHAPED POLYMER FOAMS |
摘要 |
<p>A method for producing closed cell polymer foam layers is characterized in that an emulsion which can be spread or smoothed out is produced from a solution of one or more polymers in one or more organic solution medium(s) in the form of a coherent exterior Phase A and a liquid which is to be evaporated in the form of a dispersed inner Phase B. The solution medium or the solution medium mixture of Phase A contains a higher level of liquidity than that of Phase B.</p> |
