产品描述
AXELERON™ CC B-3487 NT CPD is a high-density polyethylene cellular compound ("CPD") designed for use in foam/skin telephone wire and other cellular insulation applications. This compound incorporates a chemical blowing agent that provides up to 50% cellular expansion through temperature-controlled extrusion. AXELERON™ CC B-3487 NT CPD features a unique antioxidant system that provides superior long-term insulation aging performance in grease-filled cable applications.
The compound is recommended for hot climate applications and, using sound commercial extrusion practices, should meet the stringent insulation age testing requirements of the Telcordia GR 421 CORE and the ICEA S-84-608 specifications. AXELERON™ CC B-3487 NT CPD provides excellent extrusion processing characteristics and yields an insulation product with superior mechanical and electrical performance.
