Borealis HE4872
HDPE
博禄/北欧化工(Borealis AG/Borouge)
产品描述
It is a HDPE compound for solid insulation of symmetric data cable at high extrusion speed.
Applications
HE4872 is intended for: High frequency data transmission cables Outer skin of foam-skin constructions NOTE: If using HE4872 as telephone single insulation, especially in petroleum jelly filled cables, addition of extra stabilization may be needed to ensure long-term heat stability.
Specifications
HE4872 meets the following material classification: ISO 1872-PE, KGHN, 45-D006 ASTM D 1248 Type III, Class A, Category 4, Grade E8, E9 The following cable material standards are met by HE4872: EN 50290-2-23 1
Cables manufactured with HE4872 using sound extrusion practice normally comply with the following cable product standards: IEC 61156 EN 50288
Special Features
HE4872 consists of specially selected components to offer: Good conductor adhesion Very good flow behaviour Low die head pressure Excellent surface finish High output
