Optema™ TC 120 ExCo

Optema TC 120 is an ethylene-methyl acrylate copolymer for extrusion coating, coextrusion coating and extrusion compounding requiring good adhesion between polyethylene, polypropylene, nylon, polydichloroethylene or other substrates. It can well balance the adhesion on the substrate and the interlayer adhesion with coextruded low density polyethylene and ethylene vinyl acetate copolymer. It is an excellent heat sealing layer in co-extrusion and extrusion coating, but may require additional additives or process corrections to avoid cooling roller adhesion. Processing conditions: Excellent extrusion coating effect can be obtained in the temperature range of 260°C to 300°C (500 ° F-572 °F). It is recommended that the processing temperature should not be higher than 32 0°C (608 °F). Optema EMA can be processed on traditional extrusion equipment for extrusion coating low density polyethylene. Its wide range of thermal stability provides a wide processing window. The nozzle of the extruder should be cooled by water to avoid bridging the feed port. Surface coating is recommended to use matte cold roll surface processing.
