Safrene® M 7650
- Chemical Family
- PolyethylenesPolyolefins
Safrene® M 7650 High Density Polyethylene Resin is a bimodal high molecular weight grade suitable for extrusion blow molding of containers greater than 20 liters in volume. It has high rigidity and hardness with very good impact strength and excellent environmental stress-crack resistance properties. Safrene® M 7650 High Density Polyethylene Resin is primarily designed for the blow molding of large hollow articles but may be used for smaller moldings where exceptional environmental stress-crack resistance and impact strength are required.
