Safrene® M 7650 High Density Polyethylene Resin is a high molecular mass grade suitable for extrusion blow moulding of containers greater than 20 litre capacity. It has a high rigidity and hardness with very good impact strength and environmental stress-crack resistance properties.

Safrene® M 7650 High Density Polyethylene Resin was primarily designed for the blow moulding of large hollow articles but may be used for smaller mouldings where exceptional environmental stress-crack resistance and impact strength are required.
