LDPE Compound for Telecommunication Cables.
Low density polyethylene grade with broad molecular weight and good melt strength, suitable for sheathing communication cables . this compound has stabilized against thermal and shears degradation and ensured long-term aging properties and demonstrates excellent extrude ability. This compound has a long time service life due to excellent ESCR, weathering and UV resistance.
