GenNex® EU Ins compound has been designed to process easily on standard extruders used in the production of wire and cable products. The material has been designed to process similar to elastomeric compounds, attaining maximum output levels at relatively low shear rates. The material is supplied as free flowing pellets, packaged in sealed foil lined boxes and does not need to be dried prior to use.

PROCESSING TECHNIQUES

GenNex® EU Ins compound has been designed to process easily on standard extruders used in the production of wire and cable products. The material has been designed to process similar to elastomeric compounds, attaining maximum output levels at relatively low shear rates. Care should be taken to ensure that screw compression ratio levels are below 1.5:1, and flow restrictions in the crosshead are kept to a minimum. Melt temperatures higher than 400ºF should be avoided.

The material can be extruded using either pressure or sleeving techniques. For maximum physical properties, sleeving is recommended, with a target draw down ratio of 1.25 to 1.

The material is supplied as free flowing pellets, packaged in sealed foil lined boxes and does not need to be dried prior to use. It is recommended that the foil liners be resealed after use to prevent outside contamination or water absorption during storage. If the material has been exposed to a high humidity environment, or the foil liner has not been sealed, it is recommended the material be dried for a minimum of 4 hours at 140 ºF (60 ºC) in a standard desiccant style drier prior to use.
