摘要：

A flexible foam material having a high service temperature has been extruded from a blend of a low-density polyethylene (LDPE) resin and a syndiotactic polypropylene resin. Owing to its slow rate of crystallization, a syndiotactic polypropylene resin does not interfere with foam expansion of the polyethylene resin but provides the foam the desired temperature resistance by in-situ crystallization.
