AXELERON CS 7540 NT CPD

Linear Low Density Polyethylene Insulation Compound

The Dow Chemical Company

产品说明:

AXELERON CS 7540 NT CPD is a linear low-density polyethylene (LLDPE) extrusion compound ("CPD") produced by the UNIPOL PE Process. It is a general purpose insulation that can be used as a high speed telephone singles insulation (air-core cable only; not recommended for jelly-filled cable) and high frequency coaxial inner skin. It combines excellent electrical properties with outstanding stress crack resistance.
