New Heat-Resistant PU Rigid Foam Sheet

Yantai Wanhua Polyurethane Co., Ltd. has, in collaboration with
a research institute, developed a heat-resistant polyurethane
sheet with excellent penetrating power to electromagnetic waves.
A new application has therefore been added in the polyurethane
foam sector.
   Such polyurethane sheet is cast-molded and then cut into
desired sizes. Its properties are higher than conventional rigid
foams used in heat insulation. Its foam should have even holes
and no needle-like holes. The temperature resistance is
requested to be more than 120 degree centigrade. There should
be no shedding after cutting. There are also some requirements
on material toughness.
