Crosslinked polyolefin foam

Rodriguez-Perez, M. A. Crosslinked Polyolefin Foams Production, Structure, Properties, and Applications. Vol. 184, pp. 97-126. 

In the manufacturing of crosslinked polyolefin foam, the foam expansion and cell stabilization highly dependent on the degree of crosslinking. It has been reported that at higher crosslinking level the foam produce have higher density [1, 2]. 

A review is presented of the nitrogen autoclave process for the manufacture of crosslinked polyolefin foams. Process and product developments over the last few years are summarised and future possibilities are described. Process developments include use of higher temperatures and pressures to produce foams having densities as low as 10 kg/cub.m. Product developments include foams based on HDPE/LDPE blends, propylene copolymers and metallocene-catalysed ethylene copolymers. The structure and properties of these foams are compared with those of foams produced by alternative processes. 5 refs.

Abstract The purpose of this paper is to review the most significant developments of the last 10 years in the field of crosslinked polyolefin foams. The methods to produce the foams, the relationships between structure and properties, and the main applications of these materials are briefly reviewed. Topics of possible future research are proposed.
