ABSTRACT

Wide application of polymeric foamed materials, based on the polyolefin’s, explained by their mechanical, insulating, and operational properties. Foamed polypropylene (PP) is widely used material in numerous applications. Foamed PP products are highly demanded in automobile production, construction; some of them are used as a cushioning materials and weight reducers in complex structures. There are some practically used manufacturing technologies to produce foamed PP. But all of them have some general disadvantages. All of them are very complex and, hence, this technologies are expensive, making PP foam more costly them other foamed polyolefins. Frequently, foaming of PP requires the use of specific blowing agents, specific types of polymer, and special process conditions [1].
