Abstract: A thermoplastic elastomer (TPE) is disclosed which is markable by a laser operating at an ultra-violet wavelength because of the presence of between about 0.05 and about 0.1 weight percent of titanium dioxide or between about 0.1 and 0.3 weight percent of zinc oxide.

Abstract: A thermoplastic elastomer (TPE) compound is disclosed which has very low hardness by virtue of the use of a combination of porous styrene block copolymer thermoplastic elastomer of a molecular weight greater than 200,000 and plasticizer oil of a molecular weight less than 400 present in an amount between 85 and 91 weight percent. Super-soft extruded or molded plastic articles can be formed from pellets of the compound, with a resulting Shore OOO Hardness of between 45 and 60. Molded articles can be prepared using hot melt adhesive dispensing units.
