DGDK-6924 NT EXP1 is a high density polyethylene compound designed for use in physical foaming processes where high expansion rates (40 - 70%) are required. This compound is designed to offer excellent high speed processability as given by low extrusion pressures and smooth insulation surface quality. Furthermore, since it is fully pre-compounded with all the necessary ingredients, DGDK-6924 NT EXP1 offers better dispersion of the nucleating agent allowing high expansion rates to be achieved with more consistent processability (capacitance and diameter). It is stabilized for long term cable performance in data cable applications. Applications: Typical applications include LAN and data center cables. Specifications DGDK-6924 NT EXP1 should meet the following material specifications: - ASTM D 1248 Class A, Type III, Category 3 - ISO 1875-PE, KGHN, 45-D-045 |
