LLDPE(Low Linear Density Polyethylene)is the ideal raw materials for rotomoulding.LDPE is the copolymer of polythene,butylenes and so on with the linear molecule and the density of 0.93g/cm3.The advantage of LLDPE is it is better in liquidity,thermal stabilization and ESCR < impact,and hardness.
The basic requirement for rotomoulding equipment is to make the molder revolve around the two vertical when the molder can also be heated or cooled.The equipment usually consist of the three parts of rotational arm,heating room and cooling room.According to the way of heating.it can be divided into open fire,air heat,molten salt spreadultra red,and electronics.
