Expandable phenolic resin-coated composite beads, a process for production thereof and a process for molding thereof |
摘要 |
Expandable phenolic resin-coated composite beads comprise an aggregate having coated thereon a solid, expandable resin composition comprising a solid, phenolic resin initial condensation product, a foaming agent and, if necessary, a hardening agent. The expandable phenolic resin-coated composite beads provide composite cellular moldings in which the aggregates are uniformly dispersed in a phenolic resin-expanded layer and are firmly adhered to the expanded layer. The composite cellular moldings can be adhered to a face plate to form integral laminates.
