牌号简介	Optema TC 120是一种乙烯-丙烯酸甲酯共聚物，用于要求在聚乙烯、聚丙烯、尼龙、聚二氯乙烯或其他基材之间具有良好粘合性的挤出涂覆、共挤涂覆和挤出复合。它能很好地平衡基材上的粘合性和与共挤低密度聚乙烯和乙烯醋酸乙烯酯共聚物的夹层粘合性。它在共挤和挤出涂覆中是一种卓越的热密封层，但可能需要额外的添加剂或工艺修正以避免冷却辊粘着。加工条件：在 260°C至300°C (500° F - 572°F)温度范围之间可获得卓越的挤出涂覆效果。建议加工温度不要高于32 0°C (608°F)。 Optema EMA可在传统的挤出涂覆低密度聚乙烯用挤出设备上加工。其广泛的热稳定范围提供了较宽的加工窗口。挤出机的喷口应采用水冷却以避免进料口桥接。表面涂层建议采用哑光冷轧辊表面加工。 Optema TC 120 is an ethylene methyl acrylate copolymer intended for extrusion coating, coextrusion coating and extrusion lamination where good interlayer adhesion between polyethylene, polypropylene, nylon, PVdC or other substrates is required. It 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 Conditions: Excellent results are obtained in extrusion coating at 260°C to 300°C (500°F - 572°F) temperature range. 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.
