东莞市千泰塑胶原料有限公司为您提供pc/abs//hac-8265/织纱。pc/abs//hac-8265/织纱 pc/abs//hac-8265/织纱[title] pp has exceptional resistance to chemical solvents, acid&alkali resistance. can produce high purity pp for semiconductor industry. it is also resistant to bacterial production, suitable for disposable syringes&medical equipment. can be used for injection molding/machining&welding. can be used for plastic pipes, filter materials, microphones&other quality requirements higher than polyethylene products. the banknote is made of biaxially stretched pp (bopp) so as to improve its durability. polypropylene was discovered by the chemist giulio natta in the early 1950 in italy. in modern science, the invention of a thing may be invented at different times in different places. polypropylene is such an extreme example, was independently invented about nine times. it is the dream of a patent lawyer&litigation sc ript, to 1989 ended. polypropylene has been trying to extend the legal series, two american chemists working at philip oil j. paul hogan&robert banks, now considered to be the inventor of this material.
like its cousin polypropylene polyethylene, very cheap&plentiful supply. products from plastic bottles to carpets, plastic furniture, in the automotive industry is also very large. pp/3719/ schulman pp/2407/ schulman plastic plastic?? pp/2175/ schulman pp/3153/ schulman pp/3720/ plastic plastic?? schulman plastic? pp/1349/ schulman pp/1329/ schulman pc plastic plastic? the material itself is non-toxic, it is bisphenol a into pc material "when if the conversion is not complete, so when the temperature is likely to release bisphenol a toxic, can cause cancer. our country has been a lot of reports. prohibition of infant food container production in september 1st banned the sale of bisphenol a from june 1st of this year. the dissolution of harmful substances in food grade pp in normal&high temperature conditions. but not ordinary plastic in room temperature/high temperature will release harmful substances, harmful to human health." 07 "pc"&other common uses: kettle, cups, bottles&other combustible pom white crystalline powder, with the smell of formaldehyde. dissolve slowly in cold water, dissolve quickly in hot water. solubility in water at 20 0.24g/100cmho. insoluble in ether. soluble in caustic soda, potassium solution. the general performance of pom is a smooth, shiny, hard&compact material, yellow/white, thin part of the translucent. the combustion characteristics of easy combustion, the fire continued to burn after the flame is yellow, the upper, lower blue, melt dripping, there is a strong pungent smell of formaldehyde, fishy. pom is white powder, generally opaque, good coloring, the proportion of 1.41-1.43 g / cm3, forming shrinkage rate of 1.2-3.0%, molding temperature of 170-200 deg c, drying conditions 80-90 2 hours.
the long-term heat resistance of pom is not high, but the short-term can reach 160 deg c, the homopolymerization of pom copolymer pom high short-term heat than above 10 degrees, but the long-term heat pom copolymer rather than homopolymer pom high temperature of about 10 pom 100pe bk, pom 100pe, nc pom, 100st bk, pom 100st, nc, pom, 100ste nc, pom 100t bk pc "is a widely used material, espe-lly for manufacturing bottles, space cup, because of containing bisphenol a&controversial. experts pointed out that, in theory, as long as in the production process of the pc ii, bisphenol a 100% into plastic structure, then said no products of bisphenol a, not to mention the release. but, if there is a small amount of bisphenol a has been converted into plastic structure pc ", may be released into the food/drink. therefore, in the use of the plastic container to contain food in strict accordance with the instructions; storage&disinfection in the right way; to avoid repeated use of aging/damaged products, pc. pc, 261-3, pc, 201-8, pc, 201-5, pc, 201-15, pc, 302-5, pc, xz94248, pc, 301v-10, pc, 303-10
