Hostalen 4731 B is a high density polyethylene (HDPE) with high melt viscosity for extrusion. The product provides excellent stress crack resistance properties (ESCR) combined with very good long term hydrostatic strength, high heat- and extremely high extraction stability.
Hostalen 4731 B fullfills the requirements of DIN 16833 / ISO 24033 for PE-RT Type II.
The product can be classified as PE100 in accordance with ISO 12162, based on ISO 9080 evaluation.
Typical customer applications are underfloor heating and multilayer pipes for heating and plumbing.
Additional application is ducting of high voltage cables, where good long term heat aging stability for 50 years at 70°C is required.
