| Hanwha CLNA-8400 is a linear low density polyethylene (LLDPE) produced by the UNIPOL process. It’s molecular weight distribution is so broad that it offers an excellent processability and scorch stability. It can be used as base resin of silane-crosslinked low voltage cable insulation, high speed telephone cable insulation and high frequency coaxial inner skin. It combines excellent electrical properties with outstanding stress crack resistance. Applications: CLNA-8400 can be used as base resin of silane-crosslinked low voltage cable insulation, high speed telephone cable insulation and high frequency coaxial inner skin.&& |
