Описание материалов:
AXELERON™CX 4960 NT CPD is a kind of low density polyethylene material, which is used in the field of insulating materials. This application requires the material to have a good porous structure and low electrical loss. The product contains a heat-sensitive blow molding additive with a density between 0.40 and 0.48g/cm3.
AXELERON™CX 4960 NT CPD is widely used in coaxial cable applications, such as parallel two-wire cables and CATV cables.

| AXELERON™ CX 4960 NT CPD provides excellent surface finish and outstanding output rates over a broad range of conditions. For optimum results, use melt extrusion temperatures in the suggested range of 280 to 320°F (138-160°C). However, specific recommendations for processing conditions can be determined only when the application and type of processing equipment are known. Please contact your local Dow Wire and Cable sales representative for such particulars. |
