+HEX4460 PE80

+HEX4460 PE80

High Density Polyethylene

Product Description

HEX4460 PE80+ is a high molecular weight, high density polyethylene (HDPE) with high melt viscosity for extrusion.
This grade, which is produced by 1-hexene co-monomer, is classified as PE 80+ and provides excellent stress crack
resistance properties (ESCR) combined with very good long-term hydrostatic strength and good processability.
Typical customer applications are underfloor heating and multilayer pipe for heating and plumbing. HEX4460 PE80+
has been manufactured under Basell license.
