ABSTRACT:
A hot melt adhesive composition is based on an isotactic polypropylene random copolymer (RCP). The composition contains about 4%–50% by weight of the RCP copolymer, about 20%–65% by weight of a compatible tackifier, about 0%–40% by weight of a plasticizer, about 0%–3% by weight of a stabilizer, about 0%–40% by weight of a wax, and optionally about 0%–60% by weight of an atactic poly-α-olefin (APAO). The adhesive composition may be used in a number of applications such as, for example, in disposable nonwoven hygienic articles, paper converting, flexible packaging, wood working, carton and case sealing, labeling and other assembly applications.
