| Abstract: | Cross-linking of low-density polyethylene by electron beam irradiation was studied in this work with the aim of foam production by thermal expansion. Mechanical and thermal properties of the obtained foams were studied and it was found that relatively low doses up to 40 kGy could be used leading to a product with excellent surface appearance. |
