A process for producing non-scattering hollow plastic balloons. |
摘要 |
<p>A process for producing non-scattering hollow plastic balloons comprises forming a mixture (A) by mixing non-foamed plastic balloons and a wetting agent (a plasticizer) at a temperature below the foaming starting temperature of the non-foamed plastic balloons, bringing the mixture (A) into contact with a wetting agent (a plasticizer) (B) heated to a temperature equal to or above the foaming starting temperature of the non-foamed plastic balloons, foaming the non-foamed plastic balloons, and cooling the mixture containing the foamed plastic balloons. Non-scattering foamed plastic balloons can be obtained simultaneously with the foaming. The process needs a smaller amount of a plasticizer than the conventional process of wetting the foamed plastic balloons with a plasticizer. <IMAGE></p> |
