牌号简介 About
OREVAC 18750是一种基于马来酸酐改性聚丙烯树脂的共挤出涂料胶粘剂。它以颗粒形式存在,可用于传统的挤出和共挤设备,用于加工聚烯烃。应用OREVAC 18750是一种用于挤出涂层和挤出层压技术的粘结树脂。它被设计成在这些工艺中与铝箔、纸张或聚丙烯薄膜等基材形成粘合,并与聚丙烯和PA等树脂共挤。Orevac 18750具有优良的加工性能,特别是在拉伸性、缩颈性和熔融稳定性方面。除了粘合性能外,OREVAC 18750的特殊配方还允许设计具有受控开启力的聚丙烯或聚丙烯涂层杯和容器的铝盖。(*)对铝箔的粘合性能很大程度上取决于层压板的热条件。冷铝箔涂层的标准条件要求使用特殊的后热处理,其中OREVAC层必须再次熔化。 OREVAC® 18750 is a coextrusion coating adhesive based on a maleic anhydride modified polypropylene resin. It is available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyolefin. Applications OREVAC® 18750 is a tie resin to be used in extrusion coating and extrusion lamination technologies. It has been designed to develop adhesion in these processes onto substrates like aluminum foil (*), paper or PP films and in coextrusion with resins like PP and PA. OREVAC® 18750 exhibits excellent processing properties, particularly regarding drawability, neck-in and melt stability. In addition to adhesive properties, the special formulation of OREVAC® 18750 allows to design aluminum lids for PP or PP coated cups and containers with controlled opening forces. (*) Adhesion performance to aluminum foil is strongly dependant on thermal conditions in the laminator. Standard conditions of coating onto cold aluminum foil require using a specific post heating treatment in which the OREVAC layer must be molten again.
