HDPE Protecting cover granular
The black high density HDPE is a high molecular and high density polyethylene sheathing compound. With special formula, the
product has the properties of good weatherability, tenacity, wearability and resistance to environmental stress, can be used in production of optical cable sheath and insulation of overhead cable, and in other environments imposing stringent requirement on protective layer strength and wearability.
