PARTICULATE EXPANDABLE STYRENE POLYMERS HAVING SHORT MINIMUM MOLDING TIMES |
| 摘要 |
<p>The present invention relates to novel coating agents based on mono- and/or poly- urethanes melting below 150.degree.C for expandable particulate styrene polymers. These agents have no detrimental effect on the styrene polymers, lead to very fast-cooling moldings showing uniform density distribution throughout and good fusion, and give higher space/time yields during prefoaming.</p> |
