Patent number: 8431667Abstract: The present disclosure provides for a formula and process for making elastomeric rubber thin film articles. In particular, the formula and process is a system which produces non-Hevea or Guayule natural rubber latex (GNRL) thin film articles which have a thickness of 30-80 microns (0.03-0.08 mm), and preferably less than 40 microns (0.04 mm). These thin film articles exhibit physical strength properties similar to that of Hevea brazilensis natural rubber latex (NRL). More specifically, the disclosed thin rubber thin film articles exhibit unaged tensile strength of at least 24 MPa (about 3500 psi) and aged tensile strength of at least 19 MPa (about 2800 psi).Type: GrantFiled: December 19, 2007Date of Patent: April 30, 2013Assignee: Yulex CorporationInventors: Katrina Cornish, Jali Williams, Kc Nguyen, Brian Fishman

Publication number: 20090107510Abstract: A novel two-layer endotracheal tube (ETT) cuff for the prevention of pneumonia is disclosed. The disclosed two-layer ETT comprises a standard HVLP cuff covered with a second layer of elastomeric material with a sterile gel inserted between the layers. The two-layer cuff forms no folds when inflated in the trachea and prevents leakage, substantially reducing the risk for pneumonia attributable to standard ETT cuffs.Type: ApplicationFiled: October 29, 2007Publication date: April 30, 2009Inventors: Katrina Cornish, Jali Williams

Publication number: 20060140994Abstract: An elastomeric article having reducing microbe affinity and transmission and methods for applying and immobilizing antimicrobial compounds to the elastomeric substrate surface are disclosed. The elastomeric article has a body formed of a natural or synthetic polymer latex having an outer surface and an inner surface. The body has a coating of an antimicrobial agent over at least a portion of said outer surface. The treatment involves applying according to either a spraying or dipping process an antimicrobial polymer or composition to a surface of the elastomeric substrate; binding the antimicrobial composition to the surface in a manner such that said treat antimicrobial coating passes either one or another or both versions of a zone of inhibition test, such test including: a) a dry-leaching or agar-plate-based contact test, according to AATCC 147 protocol, or b) a wet-leaching or dynamic shake flask test according to ASTM E-2149-01 protocol.Type: ApplicationFiled: December 27, 2004Publication date: June 29, 2006Inventors: Alison Bagwell, David Koenig, Martin Shamis, Jali Williams

Patent number: 6895600Abstract: The present invention is directed to the production of elastomeric articles, such as elastomeric gloves, which can be easily stripped from forming molds, provide good tactile and gripping characteristics, and can be powder free with no halogenation or surface treatments. In general, the elastomeric articles of the invention include an ultra-thin outer layer formed of an acrylic-based polymer and a base polymer layer coagulated onto the surface of the outer layer which forms the primary matrix of the elastomeric article. The ultra-thin outer layer of the articles can be between about 0.25 microns and about 8.0 microns thick.Type: GrantFiled: December 20, 2001Date of Patent: May 24, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventor: Jali Williams

Publication number: 20050031817Abstract: An elastomeric article such as a glove includes a substrate body made of an styrene-ethylene-butylene-styrene block copolymer, and a donning layer overlying at least one side of the substrate body. The donning layer is formed of 1,2 polybutadiene, preferably syndiotactic 1,2 polybutadiene, or a chlorinated mid block unsaturated block copolymer. Optionally, a surfactant layer is present over the donning layer to further improve the donning characteristics. The surfactant layer is preferably an alkyl dimethylbenzyl quaternary, an alkyl trimethyl quaternary, a dialkyl dimethyl quaternary, sodium lauryl sulfate, or pyridinium chloride.Type: ApplicationFiled: August 7, 2003Publication date: February 10, 2005Inventors: Kermit Littleton, Ronald Gloriani, Garth Brown, Jason Baker, K C Nguyen, Jali Williams

Patent number: 6673871Abstract: Elastomeric articles, such as gloves and condoms, are disclosed including a process for making the articles. The elastomeric articles produced according to the present invention are made from a synthetic polymer. During production of the articles, the polymer is cross-linked using a metal oxide as a cross-linking agent. In one embodiment, the polymer is cross-linked without using conventional sulfur-containing cross-linking agents or accelerators.Type: GrantFiled: December 21, 2000Date of Patent: January 6, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Derek Warneke, Jali Williams
