摘要 |
<p>A one-part activator and blowing agent system for foaming plastics comprising an alkali metal borohydride and a salt hydrate blended in a single pellet or as separate pellets with a dry inert resinous polymer carrier. The one-part system is blended with a resinous polymer and then the blend extruded at a temperature at which the blend becomes molten such that the salt hydrate releases its water of hydration to hydrolyze the borohydride and produce a cellular article.</p> |
