牌號簡介 About
OREVAC 18750是一種基于馬來酸酐改性聚丙烯樹脂的共擠出涂料膠粘劑。它以顆粒形式存在,可用于傳統(tǒng)的擠出和共擠設(shè)備,用于加工聚烯烴。應(yīng)用OREVAC 18750是一種用于擠出涂層和擠出層壓技術(shù)的粘結(jié)樹脂。它被設(shè)計成在這些工藝中與鋁箔、紙張或聚丙烯薄膜等基材形成粘合,并與聚丙烯和PA等樹脂共擠。Orevac 18750具有優(yōu)良的加工性能,特別是在拉伸性、縮頸性和熔融穩(wěn)定性方面。除了粘合性能外,OREVAC 18750的特殊配方還允許設(shè)計具有受控開啟力的聚丙烯或聚丙烯涂層杯和容器的鋁蓋。(*)對鋁箔的粘合性能很大程度上取決于層壓板的熱條件。冷鋁箔涂層的標(biāo)準(zhǔn)條件要求使用特殊的后熱處理,其中OREVAC層必須再次熔化。 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.
