Abstract
The present invention relates to a composition for application in rotomolding processes comprising a blend of linear low density polyethylene (LLDPE) in concentrations from 20 to 40% by weight and melt flow index from 1 to 4 g/10 min; high density polyethylene (HDPE) in concentrations from 20 to 40% by weight and melt flow index from 5 to 9 g/10 min; low density polyethylene (LDPE) in concentrations from 0 to 20% by weight and melt flow index from 6 to 10 g/10 min; and linear low density polyethylene (LLDPE) in concentrations from 20 to 40% by weight and melt flow index from 3 to 7 g/10 min. A composition comprising feedstock of renewable origin, as well as its use is also disclosed.
Claims12
A composition for application in rotomolding processes, comprising:
- a first linear low density polyethylene (LLDPE) in concentrations from 20 to 40% by weight and melt flow index from 1 to 4 g/10 min;
- high density polyethylene (HDPE) in concentrations from 20 to 40% by weight and melt flow index from 5 to 9 g/10 min;
- low density polyethylene (LDPE) in concentrations from 0.5 to 20% by weight and melt flow index from 6 to 10 g/10 min;
- and
- a second linear low density polyethylene (LLDPE) different from the first LLDPE in concentrations from 20 to 40% by weight and melt flow index from 3 to 7 g/10 min;
- wherein the melt flow index (I216) is measured according to ASTM D1238.
