Abstract
Composite panels with plastic core of polyvinylchloride and metal outer layers bonded to the core by means of adhesive layers, including those where flame retardant additives are incorporated in the plastic core, do not exhibit completely satisfactory properties for certain applications, in particular with respect to behavior under fire conditions viz., the creation of smoke. Composite panels having a plastic core of post-chlorinated polyvinylchloride or a mixture of the same with polyvinylchloride avoid these disadvantages.
