  • Hot melt adhesive based on ethylene-propylene rubber (EPR) and semicrystalline olefinic polymers
    Patent number: 6143818
    Abstract: An elastomeric-based hot melt adhesive composition having a variety of end uses, particularly in construction and elastic attachment applications on nonwoven disposable articles. The composition includes an elastomeric rubber polymer or a mixture of elastomeric rubber polymers together with a semicrystalline olefinic polymer or a mixture of semicrystalline olefinic polymers, a tackifier resin, a plasticizer, a wax and a stabilizer. The preferred elastomeric rubber polymer is an ethylene-propylene rubber copolymer (EPR) and/or an ethylene-propylene diene monomer rubber terpolymer (EPDM). The hot melt adhesive composition can be applied using common application techniques such as extruding or spraying.
