Genflam® OH‐SD BK thermoplastic flame retardant low smoke zero halogen (LSZH) compounds are designed to process easily on standard extruders used in the production of wire and cable products. These materials are designed to process similar to elastomeric compounds, attaining maximum output levels at relatively low shear rates. The material can be extruded using either pressure or sleeving techniques. For generation of optimum physical properties, a draw down ratio of 1.25:1 can be used. All materials are supplied as free flowing pellets, packaged in sealed foil lined boxes and do not need to be dried prior to use.

PROCESSING TECHNIQUES

Genflam® OH‐SD BK has been designed to process easily on standard extruders used in the production of wire and cable products. This 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 temperature values above 420ºF (215ºC) should be avoided. The material can be extruded using either pressure or sleeving techniques. For generation of optimum physical properties, a draw down ratio of 1.25:1 can be used. The material is supplied as free flowing pellets, packaged in sealed foil lined boxes and do 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 140ºF (60ºC) in a standard desiccant style dryer prior to use.
