New generation of polyethylene rotational molding tanks contain a foam layer. Lightness along with good strength are the main advantages of placing a foam layer in the structure of rotational molding polyethylene tanks. SISCO supplies ready to use polyethylene foam in powder form for rotational molding. This product is used as a single layer in multilayer tanks and has good adhesion to polyethylene without foam.

SISCO offers foam-capable polyethylene powders in a variety of colors according to regular grades.
