in the rotomoulding value chain
Polythene, in all its forms, is still the most widely-used material in rotomoulding: it covers 80 to 90% of all polymers. For all that, other polymers are incorporated into the rotomoulding process to respond to specific problems. Plastics must meet two conditions to be suitable for rotomoulding: High thermal stability and very low material viscosity when melted.
Rotomoulding is a plastic processing technique. The technique is based on the rotation and heating of a mould. These two elements together marry the plastics gradually to the shape of the mould. Thus was born the word rotomoulding - moulding by rotation. In practice, there are five steps in processing the plastic:
