Recommended

EPC9902 can be processed on PVC / PE extruders.

Melt temperature: control extrusion temperature below 165°C, maximum not to exceed 175°C.

Screw & Head: lowcompressionratio screw is recommended.

Screen pack and breaker plate are generally not required. Screw cooling is not needed.

For special extruders or applications, please contact our company for further process information.

Processing Guide

The material is delivered in aluminumplastic bags (bag or carton packing). No special drying is required if package remains intact. If stored for long period under humid environment, drying at 70 °C for 4 hours in dehumidifying dryer is recommended.

Natural-colored EPC9902 can be color-compounded. Our company supplies full range of color masterbatches for coloring requirement.
We recommend customers perform comprehensive evaluation on final cable construction to verify material suitability.
