Agricultural workers rely on chemically protective gloves for protection from dermal exposure to insecticides. In Australia the most widely used gloves are manufactured from polyvinyl chloride or nitrile butadiene rubber. During insecticide application splashes and spills frequently occur on the external surfaces of gloves which may compromise the integrity of the membrane. Interaction of two o...

in this work, novel thin film composite membranes (tfcs) of poly (ether-6-block amide) (pebax-1657) on a polyvinyl chloride (pvc) ultrafiltration membrane as support were prepared using inclined coating method for co2 separation. investigating the effects of top selective layer thickness formed by controlling the coating angle (15-60°) and polymer solution concentration (5-10 wt.%), and also, t...

Polyvinyl chloride (PVC) is made by polymerizing vinyl chloride monomer and is a plastic that softens on heating. The addition of a small amount (<5%) of plasticizer produces a hard PVC, whereas the addition of 30 to 50% plasticizer results in a soft PVC. Soft PVC is used to make several products, including chemical shoes, cables, gloves, hoses, and film. The principal component of PVC hose is ...

Investigations of the effect of the excitation light wavelength on the intensity distribution in the fluorescence band of l,4-diphenyl-l,3-butadiene (DPB) in polyvinyl alcohol) films (PVA) at 296 and 87 K for samples before and after heating to 423 K, and fluorescence lifetime measurements have shown that trans-trans and cis-trans conformers are responsible for the emission of fluorescence. The...

BACKGROUND Contact allergy to plastic gloves is rare. Benzisothiazolinone is a biocide that is mainly used in industrial settings. We first suspected delayed-type contact allergy to benzisothiazolinone from polyvinyl chloride (PVC) gloves in 2004. We looked through our medical records from 1991 to 2005 to find similar cases. OBSERVATIONS We found a total of 8 patients who are allergic to benz...

Three types of chloride-conducting membranes based on polyvinyl chloride, commercial gelatin, and polyvinyldifluoride-hexafluoropolymer are introduced in this report. The polymers are mixed with chloride-containing salts, such as tetrabutylammonium chloride, and cast to form membranes. We studied the structural properties, thermal stability, and electrochemical response of the membranes to unde...
