| BPD 4035 is a black medium density polyethylene compound designed for cable jacketing. It contains 2.3% of a well dispersed carbon black and an antioxidant package leading to a complete outdoor weatherability and excellent ageing properties. BPD 4035 is based on a polymer which offers an excellent resistance to environmental stress cracking, good low temperature properties, and an excellent extrudability. The polymer density has been chosen near the upper limit of MDPE in order to retain maximum mechanical properties, and resistance to heat deformation.&& |
