Patent number: 10065210Abstract: Provided, among other things, is a breach or contamination indicating elastomeric article for indicating a breach or contamination by a selected chemical or group of chemicals, the article having an exterior and interior and comprising: (1) an interior elastomeric layer selected to resist permeation by the selected chemical(s); and (2) exterior thereto, a contiguous or dis-contiguous first indicating layer comprising a dye or pigment and an opacifying agent, the dye or pigment providing the layer with color, the first indicating layer changing color and/or opacity when contacted with a selected chemical such regions of the article where the layer is so contacted contrast with non-contacted regions. A subsequent, interior layer can provide a safety buffer allowing for removal or disposal prior to any potential for harm. A second, interior indicating layer can be used to make the warning louder when a serious breach is occurring.Type: GrantFiled: June 11, 2015Date of Patent: September 4, 2018Assignee: Ansell LimitedInventors: Noorman Abu Hassan, Fazli bin Shani, Darryl Nazareth

Patent number: 6378137Abstract: A powder free medical glove having an outer side a silicon treated surface and the inside of cross linked coagulated glove bonded with a layer formed of an anti-blocking composition. The anti-blocking composition comprises of a polymer or copolymer mixed together with a micronized high density polyethylene material and wax in suitable blends that result in the composition having anti-blocking and improved lubricity properties. The medical glove with the skin contacting anti-blocking coating enables donning of the glove to be effected without the aid of donning powder such as starch powder. When the finished glove is washed and rinsed with water to remove the coagulant powder, and the said glove treated with a silicon solution, a glove substantially free of loose powder glove is produced and has good lubricity for donning.Type: GrantFiled: January 19, 2000Date of Patent: April 30, 2002Assignee: Ansell Shah Alam Sdn BhdInventors: Noorman Abu Hassan, Chak Choy Yuen
