Allergic contact dermatitis caused by triphenyl phosphite in poly(vinyl chloride) gloves.

Abstract: Contact dermatitis caused by vinyl gloves is considered to be very rare, and identification of the allergen can be difficult. Bisphenol A, adipic polyester, mono(2-ethylhexyl) maleate in di-(n-octyl)tin-bis(2-ethylhexylmaleate), benzisothiazolinone and formaldehyde are identified allergens in poly(vinyl chloride) (PVC) gloves. Here, a patient with contact dermatitis caused by triphenyl phosphite (TPP) in PVC gloves is presented.

Comparison of the Effect of an Organoclay, Triphenylphosphate, and a Mixture of Both on the Degradation and Combustion Behaviour of PC/ABS Blends

Abstract: Polycarbonate Acrylonitrile-Butadiene-Styrene blends (PC/ABS) with flame retardants Triphenyl Phosphate (TPP), nanoclay and their mixtures were prepared in a twin- screw extruder. The morphological properties were characterized by X-ray diffractometry (XRD) which showed the intercalated structure of nanoclay in the matrix. Thermal stability of the samples was studied using Thermogravimetric Analysis (TGA), and the degradation kinetic parameters were determined using various methods including Kissinger, Flynn-Wall-Ozawa and Coats-Redfern methods. It was found that the sample containing both TPP and nanoclay has the highest activation energy. The activation energy order of PC/ABS blends with different flame retardant packages, obtained by Kissinger method agrees well with that obtained by Coats-Redfern. Cone calorimetry and limited oxygen index (LOI)/underwriters laboratory 9 4 (UL 94 ) methods were used to investigate the fire behaviour and flammability of materials. The reduced mass loss rate (MLR), peak heat release rate (PHRR) and enhanced LOI of the composite containing mixture system confirmed a synergistic effect of TPP and nanoclay.

Flame-retardant thermoplastic resin composition

Abstract: PROBLEM TO BE SOLVED: To prevent dripping during burning by melt-kneading a thermoplastic resin, a phosphorus-containing flame retardant and a layered silicate in a specified ratio SOLUTION: 100 ptswt thermoplastic resin (eg polycarbonate resin) having a number-average molecular weight of 5,000-100,000 is mixed with 05-50 ptswt phosphorus-containing flame retardant represented by formula I (wherein R to R are each H or a 1-6 C alkyl; R is a group represented by formula II or III; and n is 0 or 1-4), eg triphenyl phosphate The obtained mixture is mixed with 001-20 ptswt layered silicate (eg modified montmorillonite containing 10meq/100g of intercalated quat organic onium ions (eg dimethyldioctylammonium ions)) having a mean particle diameter of 05-300μm and an average aspect ratio of 80 or above and optionally additives such as a light stabilizer, an ultraviolet absorber, an antioxidant and an antistatic agent, and the resulting mixture is melt-kneaded with eg an extruder to obtain a flame-retardant resin composition
