| Abstract: | A kind of linear low density polyethylene(LLDPE) special resin for rotational moulding was developed and produced with gas phase fluid-bed polyethylene process in a LLDPE plant.The property tests and application of the special resin,denoted as grade MLPE-8060,was performed.The stable production and the precise control of melt flow rate and density of MLPE-8060 was realized in the mode of condensation operation.The results show that: the special resin can stand comparison with the level of its imported counterparts,especially in tensile fracture stress and charpy impact strength.The special resin can use as the modified base resin,and the formability and weatherability of special resin can meet the requirements of the manufacturers. |
