摘要

Coextruded polypropylene multilayer sheet comprises at least three layers. The multilayer includes two polypropylene homopolymer layers with an intermediate layer between them. The intermediate layer comprises a rubber-modified polypropylene random copolymer which is mixed with a styrene-ethylene-butylene (SEB) or styrene-ethylene-propylene (SEP) copolymer.
