Patent number: 6984688Abstract: A plasticized HSBC blended with polypropylene and free of a filler material which adversely affects clarity, provides an injection-moldable composition for an article required to have specific properties, namely, tensile strength in the range from about 4.13 to 8.96 MPa (600 to 1300 psi); tear strength in the range from about 21 to 52.6 N/mm (120 to 300 lbs/in); softness in the range from about 45 but less than 65 Shore A; and haze less than 20%, measured by ASTM D1003 using a BYK Gardner Micro Tri-gloss 4525 meter; and it is essential that all of these properties, along with the physical dimensions of the molded article, remain substantially unchanged after immersion of the article in boiling water for 1 hour. Such a composition is may be injection molded to form a nipple for feeding an infant, or a teething ring, or goggles for a diver, and the articles are sterilizable and recyclable.Type: GrantFiled: May 2, 2003Date of Patent: January 10, 2006Assignee: GLS CorpInventor: Jiren Gu

Publication number: 20020187333Abstract: The present invention provides a process for effectively extruding a polypropylene polymer onto a cellulosic substrate. In the process, a polypropylene polymer is co-extruded with a polyolefin polymer other than polypropylene so as to stabilize the molten polypropylene polymer layer. Co-extrusion also allows extruding the polypropylene polymer at elevated temperatures so that the polypropylene is oxidized. Thus the polypropylene layer more readily bonds to a substrate without requiring a primer or ozone pretreatment step.Type: ApplicationFiled: May 23, 2001Publication date: December 12, 2002Inventor: Jiren Gu
