Arya Sasol HEX4460 PE80+ High Density Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE)
Material Notes:	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. Application: Drinking water pipe, drainage pipe, plumbing, heating & cooling Forms: Pellets Attribute: Good Resistance to SCG & RCP; Good Processability; Outstanding ESCR; Good Creep Strength; Good Chemical Resistance; Very Good Low Temp. Impact Resistance Additives: Antioxidant: Yes; Processing Aid: No; Antiblock: No; Slip Agent: No Information provided by
