TL;DR: In this article, a heat-resistant flame-retardant polyvinyl chloride cable material and a manufacturing method for its manufacturing was described. And the material has the advantages that: a large amount of graphite serving as a flame retardant and high-temperature-resistant filler is added; and the graphite and a proper amount of chlorinated paraffin and zinc stannate together assist in enhancing the flame retardent property of a cable.
Abstract: The invention relates to a heat-resistant flame-retardant polyvinyl chloride cable material and a manufacturing method thereof. According to a formula, the material comprises the following components: polyvinyl chloride resin, a flame-retardant filler, a dispersing agent, a plasticizer, lead sulfate tribasic, dibasic lead phosphate, lead stearate, isopropyl triphenyl phosphate, chlorinated paraffin, calcium carbonate, zinc stannate, water and zinc borate, an antioxidant and stearic acid. The material has the advantages that: a large amount of graphite serving as a flame-retardant and high-temperature-resistant filler is added; and the graphite and a proper amount of chlorinated paraffin and zinc stannate together assist in enhancing the flame retardant property of a cable. The filler has high compatibility with other materials and high dispersion and is matched with other stabilizers; and the product has high heat-resistant stability and flame retardant property. Meanwhile, the lubricating performance of the product is improved to a great extent; the PVC mixed material has high uniform plasticity and high-speed melt fluidity; and the product has a smooth surface, soft handfeel andsuperior performance.

TL;DR: In this article, the polyester resin is characterized by comprising the following ingredients in percentage by mass: 0 to 10 percent of ethylene glycol, 10 to 40 percent of neopentyl glycol and 0 to 8 percent of 1,6-ethylene glycol.
Abstract: The invention relates to polyester resin for low-temperature cured powder paint and a preparation method of the polyester resin. The polyester resin is characterized by comprising the following ingredients in percentage by mass: 0 to 10 percent of ethylene glycol, 10 to 40 percent of neopentyl glycol, 0 to 8 percent of 1,6-ethylene glycol, 0 to 5 percent of 1,4-cyclohexanedimethanol, 20 to 60 percent of terephthalic acids, 2 to 15 percent of adipic acid, 0.05 to 0.2 percent of monobutyltin oxide, 0.02 to 0.15 percent of triphenyl phosphate, 0 to 5 percent of adipic acid, 2 to 40 percent of m-phthalic acid and 0 to 5 percent of methacrylic acid. The polyester resin and the preparation method have the advantages that the curing at the low temperature condition of 130 DEG C to 140 DEG C can be realized, in addition, the storage stability is good, and the like.

TL;DR: Two flame retardants, triphenyl phosphate and 2-ethylhexyldi-phenyl phosphate (EHDPP), were added to two small artificial ponds (3 m3 volume) to give water concentrations of 60 μg/L for each compound as discussed by the authors.
Abstract: Two phosphate ester flame retardants, triphenyl phosphate (TPP) and 2-ethylhexyldi-phenyl phosphate (EHDPP) (both 14C-labelled) were added to two small artificial ponds (3 m3 volume) to give water concentrations of 60 μg/L for each compound. Both phosphate esters had half-lives of about 15 h in the water column and showed rapid sorption to bottom sediment. At 24 h posttreatment an estimated 28% of EHDPP and 9% of TPP added could not be accounted for by measurements of radioactivity in water, sediment and biota. Calculations of volatilization rates from water of the two compounds suggested that losses of EHDPP may have been due in part to volatilization. Bioconcentration of TPP by fathead minnows (Pimephales promelas) was similar to that predicted from laboratory studies on the uptake and clearance of TPP by rainbow trout (Salmo gairdneri). Prediction of the bioconcentration of EHDPP by duckweed (Lemna minor) from laboratory studies underestimated the rapid uptake of this compound observed in the ponds.
