Properties of high fluidity polyethylene for rotational moulding
High fluidity polyethylene R335L for rotational moulding was developed in gas phase polyethylene plant,whose properties were analyzed by gel permeation chromatography,rotational rheometer,differential scanning calorimeter,and polarizing microscope.The results show that R335L shows a wider molecular mass distribution and obvious shear-thinning characteristics,whose tensile yield stress is 13.4 MPa and charpy notched impact strength is 65.0 kJ/m2.R335L performs excedently in processability and moulding properties,good melting and crystallization properties,good mechanical properties.
