Optema™ TC 220 ExCo

Optema™ TC 220 ExCo by ExxonMobil Chemical is an ethylene methyl acrylate copolymer stabilised with a thermal stabilizer. It is an excellent grade for coextrusion coating and extrusion lamination where good interlayer adhesion between polyethylene, polypropylene, nylon, PVdC or other substrates is required. It can be used for making alloys, blends and compounds where softness and flexibility are required. Processing temperatures above 320°C (608°F) are not recommended. Optema™ TC 220 ExCo can be processed on conventional extrusion equipment designed for extrusion coating LDPE. Their broad thermal stability range offer wide processing conditions window. Water cooling of extruder throat is preferred to avoid hopper bridging. Excellent results are obtained in extrusion coating at 260°C to 300°C (500°F - 572°F) temperature range.
