Process for expanding microspheres |
摘要 |
A process for expanding expandable thermoplastic microspheres containing a blowing agent which will be volatilized at heating. A slurry of the unexpanded spheres is fed to a pressure zone together with steam whereby volatilization of the blowing agent occurs in the zone and the expanded microspheres are then allowed to leave the zone at a considerable pressure drop.
