Patent number: 11441009Abstract: A polyvinyl halide compound, alone or alloyed with thermoplastic polyurethane, is used as a flexible layer for over-molding a rigid polymer substrate. Selection of types and amounts of calcium carbonate for the overmolding layer improves peel strength to achieve cohesive failure of the flexible overmolding layer rather than adhesive failure of the interface between the flexible overmolding layer and the rigid polymer substrate.Type: GrantFiled: December 13, 2017Date of Patent: September 13, 2022Assignee: GEON Performance Solutions, LLCInventors: Sang Lee, Ling Hu, Craig L. Shoemaker, Robert Schilling

Publication number: 20200216586Abstract: This invention relates to plasticized poly(vinyl chloride) compounds formulated to provide sufficient flexibility and flame retardance to be suitable for building and construction polymeric articles. One aspect of the present invention is a flame retardant poly(vinyl chloride) compound, comprising a mixture of: poly(vinyl chloride); a plasticizer selected from the group consisting of polymeric plasticizer, alkyl aryl fire retardant plasticizer, and combinations thereof; and optionally functional additives, wherein the mixture has i) a Limiting Oxygen Index of greater than 50% according to ASTM D2863; ii) an Elongation at Break of at least 10% according to ASTM D638 (Type IV); and iii) a Modulus of Elasticity of less than about 15,000 psi according to ASTM 638 (Type IV).Type: ApplicationFiled: September 11, 2018Publication date: July 9, 2020Applicant: Geon Performance Solutions, LLCInventors: Craig L. Shoemaker, Amjad Abu-Ali

Publication number: 20160260519Abstract: A mixture of poly(vinyl halide) and epoxidized benzyl fatty acid ester, preferably epoxidized benzyl soyate (EBS), is disclosed. The epoxidized benzyl fatty acid ester as a plasticizer replaces common high molecular weight phthalates, such as diisodecyl phthalate (DIDP), which are conventionally used for the manufacture of wire and cable insulation and jacketing. The epoxidized benzyl fatty acid ester, a bio-plasticizer, unexpectedly outperforms the higher molecular weight DIDP as demonstrated by superior retention of Strain at Break after accelerated aging at elevated temperatures.Type: ApplicationFiled: September 23, 2014Publication date: September 8, 2016Applicant: PolyOne CorporationInventors: Stephen D. HORTON, Craig L. SHOEMAKER, Alan BARCON

Publication number: 20140116749Abstract: Use of polycaprolactone plasticizer is disclosed for flexible polyvinyl chloride compounds. The compounds can pass the very demanding UL-910 plenum burn test for usage in wire and cable articles.Type: ApplicationFiled: March 12, 2013Publication date: May 1, 2014Applicant: POLYONE CORPORATIONInventors: Craig L SHOEMAKER, Sang LEE, John L GRANT, Joe BERTINO, Alan BARCON

Patent number: 6352039Abstract: A plastic pallet (10) having good load bearing construction and held together without mechanical fasteners, includes deck boards (30). The deck boards include ridges (24) on an upper side (32) and a lower side (34) thereof. Deck boards are positioned transversely on stringers (12) and joined thereto by either an adhesive or thermoplastic welding processes. The stringers and deck boards may be provided with end caps (26, 42) which seal interior areas of the stringers and deck boards and prevent tearing thereof. The stringers and deck boards have interior reinforcement ribs (22,40). The cross sectional profiles of the stringers, deck boards, and end caps provide a cost effective and light weight pallet. Openings which extend between the stringers allow for either two way fork entry and/or four way fork entry. The stringers and deck boards provide flexibility in constructing pallets of various designs. The plastic pallet preferably is highly durable and fully recyclable.Type: GrantFiled: March 9, 2001Date of Patent: March 5, 2002Assignee: The Geon CompanyInventors: Martin E. Woods, Craig L. Shoemaker, David W. Taylor, Patrick C. Booth

Patent number: 5298558Abstract: The present invention relates to electrostatic dissipative impact modified polymeric compositions comprising an effective amount of a chain extended block copolymer, polyvinyl halide and no more than 10 weight parts of a polymeric impact modifier per 100 weight parts of polyvinyl chloride. The chain extended block copolymer is formed from reacting a di-functional polyether with a chain extender which is a condensate selected from the group consisting of polyundecanolactam, polydodecanolactam, poly(11-aminoundecanoic acid) and (12-aminododecanoic acid).Type: GrantFiled: June 2, 1992Date of Patent: March 29, 1994Assignee: The Geon CompanyInventors: Francis R.
