SUPER-SOFT THERMOPLASTIC ELASTOMERS

摘要

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.
