Rotational molding techniques, also referred to as rotomolding or rotational casting, can be used to make hollow items of any size and of any desired shape.

The rotational molding process uses plastic powder to form a desired product. The mold is placed in an oven applying a biaxial rotation until melted plastic covers all parts of the mold to produce the desired hollow plastic product and is then cooled to solidify.

LyondellBasell produces a range of HDPE and LLDPE Petrothene and Lupolen pellets, as well as Microthene powders, for use in the most demanding rotational molding applications.
