ZC-5323 (Insulation) & ZC-5327 (Sheath) are advanced LSZH (Low Smoke Zero Halogen) compounds designed for high-performance photovoltaic (PV) and medium-voltage cable applications. They combine halogen-free safety, low smoke emission, and excellent thermal/mechanical stability with irradiation crosslinking capability for continuous operation up to 125 °C.
Halogen-free & low smoke – Meets LSZH system requirements with low acid gas release, ideal for PV cable environments.
High thermal & mechanical stability – Irradiation-crosslinkable for enhanced performance at 125 °C continuous service temperature.
Smooth processing – Suitable for conventional single-screw extrusion; stable melt with recommended three-layer screen pack.
Fire safety – High oxygen index for sheath performance, balanced electrical insulation properties.
Standards compliance – Designed to meet EN 50618:2014 and UL 4703:2014 (current test reports available on request).
