Molecular weight rotational moulding

Low molecular weight, narrow MWD polymer—used widely for injection moulding and rotational moulding. 

Metallocene PF is made with a metallocene catalyst or single-site catalyst (SSC) in a slurry loop process. These grades are copolymer materials with very narrow MWD, specifically formulated for rotational moulding. These materials have superior mechanical properties, a significantly reduced low molecular weight (i.e., extractable) content, and even better whiteness than the traditional LLDPE materials. Metallocene grades now account for about 15% of global LLDPE consumption...
