Biotesting of industrial wastewater from foam rubber manufacture

Biotesting of industrial wastewater from foam rubber manufacture. Usov, G. P.; Tryakhova, T. I.; Svetlakova, G. N.; Rozanova, L. I. (USSR). Khim. Tekhnol. Vody, 9(2), 182-4 (Russian) 1987. CODEN: KTVODL. 9003-55-8 and 135-88-6 are cas registry numbers of chemicals which are used as reagents here. ISSN: 0204-3556. DOCUMENT TYPE: Journal CA Section: 60 (Waste Treatment and Disposal) Section cross-reference(s): 39 Wastewaters from latex foam rubber manuf. exhibit toxicity with respect to microflora of biol. wastewater treatment plants and to aquatic organisms. The wastewaters contg. latexes, Na2SiF6, and rubber accelerators (DA [14324-55-1] and ZM [155-04-4]) are most toxic to the microflora of biol. wastewater treatment plants and therefore should be dild. 3100 times. .

Flame-retardant flexible urethane foams

Flame-retardant flexible urethane foams. Cobbledick, David Stanley (General Tire and Rubber Co., USA). U.S. US 4018724 19 Apr 1977, 8 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08J009-00. NCL: 260002500AB. APPLICATION: US 75-632940 18 Nov 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Discoloration of polyurethane foams contg. flame retardants, such as PVC, ZnO, Sb2O3, and chlorinated paraffins, is prevented by the use of 0.05-5.00 parts 2-mercaptobenzothiazole zinc salt (I) [155-04-4]. Thus, polypropylene glycol glycerol triether-TDI copolymer [39279-01-1], contg. PVC, Sb2O3, and ZnO flame retardants and 0.5 phr I, was foamed by conventional procedures to give a fire-resistant product which showed no discoloration after heat aging at 160.degree. for 90 min, compared with a product whose center turned pink during prepn., and turned dark purple after heat aging at 160.degree. for 90 min.
