ARAK-LL0220AA

1 product description

LL0220AA is a linear low density polyethylene copolymer containing butene-1 as a co-monomer. LL0220AA has been specially developed for production of hand wrap and other cast stretch films such as oriented tapes. It can also be used as a blending partner in LDPE or LLDPE in both cast and blown film applications.

2 applications

LL0220AA offers the following advantages when it processed by the cast extrusion process:

Good balance of mechanical properties.
Good optical properties.
Good cling performance.

LL0220AA also can be used as compounds for low voltage power cable insulation or fibre optic jacketing.

LL0220AA should be processed in machinery designed for LLDPE.

Melt temperature range in the cast process are normally 240°C-280°C and in lean blends for blown film are 165°C-215°C.

LL0220AA should be stored in the dry condition below the 50°C and avoided from the exposure of direct sunlight.
