| description | A hot melt pressure sensitive adhesive (HMPSA) is obtained by combining a linear A-B-A block copolymer, wherein the B component is polyisoprene and the A component is polystyrene (S-I-S), at least one compatible tackifying resin, at least one plasticizer, antioxidant(s) and stabilizer(s) and optionally a wax, wherein the A-B-A block copolymer contains 0 to 10 % by weight residual A-B diblock. The HMPSA is suitable as a positioning adhesive for disposable articles like plasters, bandages, sanitary napkins, e. g. feminine napkins, adult incontinent pads or diapers. The HMPSA has a viscosity from 3,500 mPas to 25,000 mPas at 140° C. and exhibits adhesion values from 1.0 to 3.0 N/cm at coat weights of 10 to 25 grams per square meter. |
