ABSTRACT:
A hot melt adhesive consisting essentially of amorphous polypropylene, styrene-based themoplastic elastomer, tackifier and wax having a dissipation factor of about 0.010 or less at 1 kilohertz at 23.degree. C., and a volume resistivity of at least about 1.times.10.sup.14 ohm-cm at 23.degree. C. Such adhesives exhibit good shear strength and shock resistance.
