    In the process of rotational molding. Require raw materials can flows easily and do not break down under the conditions of high temperature without pressure , which caused only a small part can meet the three requirements to used as rotational molding raw materials in a huge plastic category: First, the raw materialsn must have good liquidity after melton in the situation of no pressure; Second, the raw material can be more easily made into the powder or paste before put into the mold cavity; Third,the raw material should have good thermal stability when heating and melting ,and will not break down at a certain period of time. Polyethylene (PE), followed by polyvinyl chloride (PVC), and other polypropylene (PP), nylon (PA), polycarbonate (PC), Polyoxymethylene (POM), fluoropolymers, EVA, PBT and TPU also meet these three characteristics under certain conditions, so these plastics constitute the scope of raw materials for rotational molding, in which polyethylene accounts for rotational molding About 95% of raw materials.
