Shear Adhesion Failure Temperature (SAFT), Kraft/Kraft (Huntsman Method): 93° C. Open Time ... 如:高阻隔复合塑料瓶、高阻隔复合油箱、复合薄膜、复合片材等。

耐低温高内聚长开放时间的APAO原料。众所周知,APAO作为热熔胶存在低温性能差的缺陷。Rextac公司的2880A这个产品很好的解决了低温性能差的缺陷。
RT2880A的产品特性如下。
Adhesive and Sealant Grade.
Description: Butene-1 copolymer and FDA compliant
Features: Very low softening point and excellent tensile properties
Applications: Component of hot melt adhesives, sealants and specialty products
Other Properties:
Ring and Ball Softening Point (ASTM E 28): 93°C.
Needle Penetration (ASTM D 1321): 10 mm.
Shear Adhesion Failure Temperature (SAFT), Kraft/Kraft (Huntsman Method): 93°C.
Open Time, Kraft/Kraft (Huntsman Method): > 240 sec.
Flashpoint, COC (ASTM D 93): >235°C.
由此可知 RT2880A有很低的玻璃化温度,由此保证了此产品低温下不会转变为固态结晶。一般耐低温的产品内聚强度都比较差,而RT2880A这款产品的内聚强度可以达到2,97MPa。开放时间近4分钟,由于有这些特质,因此这款产品低温性能优异。
此产品粘度只有8000 CPS,粘度较低可用于床垫、地毯喷胶,长的开放时间保证有充足的时间贴合。并且内聚强度优于其它APAO产品。
RT2880A产品填补了APAO热熔胶低温性能差的缺陷,尤其是在中国北方尤为适合此产品。
