Optema™ TC 120 ExCo

Optema™ TC 120 ExCo by ExxonMobil Chemical is an ethylene methyl acrylate copolymer stabilised with a thermal stabilizer. It is intended for extrusion coating and coextrusion coating where good interlayer adhesion between polyethylene, polypropylene, nylon, PVdC or other substrates is required. Optema™ TC 120 ExCo offers excellent balance of adhesion onto the substrates and interlayer adhesion with coextruded LDPE and EVA's. It is an excellent heat seal layer in coextrusion and in extrusion coating but additional additives or process modifications may be required to prevent chill roll sticking. Processing temperatures above 320°C (608°F) are not recommended. Optema EMA can be processed on conventional extrusion equipment designed for extrusion coating LDPE. Their broad thermal stability range offers wide processing conditions window. Water cooling of extruder throat is preferred to avoid hopper bridging. Matte chill roll finishing is recommended for top coating. Excellent results are obtained in extrusion coating at 260°C to 300°C (500°F - 572°F) temperature range.
