Shanghai Daoqin Plastics Co., Ltd.

        PC既 polycarbonate (PC), is most Common plastics 之一, this type of material 本身无毒, especially more used for manufacturing bottle, 太空杯 and other, is has di 酚A而备受争议. upper, need in made as PC process in di 酚A百 separation 之百转化 formed plastics structure, table/sheet products full has di 酚A, 也就变 for 健康没 has property. is, has small amount di 酚A没 has formed PC plastics structure, can can 会释出而进入食 material or product in, use 者, especially is less year safety.

        PP is polypropylene (PP) shrink 写, it tool has good heat resistant property, products can in 100℃ above temperature degree 进行消毒灭菌, in outer force conditions lower, 150℃也不 deformation, is most Common micro use plastics 之一. is fine 调查会发现, upper PC材 material products ratio PP材 material products 卖 贵, 顾客们往往会奔 “越贵 quality good ” 理念 挑选, its price is is currently market upper 1吨PC price high 于1吨PP price. types material versus comparison 会发现, PP wear resistance ratio PC差一, therefore in made as transparent 杯子时, generally selection PC as is material, PC products ratio PP products need more 美观. is from safety degree 说, PP plastics manufacturing processing temperature degree to 180～240℃, therefore water it separation understanding, therefore PP ratio PC more add safety.

        PC water 杯里装开 water has 危害吗?

        杯底数字 is 7 water is use polycarbonate (PC) 做, 即PC. generally PC材质 plastics can resistant -30-140℃ temperature degree, this is material physical properties, is this type of material in this type of temperature degree lower use is cracking, 熔化. is 当我们 from food safety degree 出发会发现, temperature degree high, PC in di 酚A释放 amount more, but also speed degree fast. therefore PC之 therefore in 健康威胁 is is in high temperature it 会释放 di 酚A, that this let 人“闻之 color 变” di 酚A to is 何方神圣呢? di 酚A(BPA) is in industrial upper by use combined formed PC and ring oxygen resin and other material. in industrial 里, di 酚A can is 无处不 in, from water bottle, medical devices to food packaging inner 里, has it 身影. year, full world production will has 2700 10,000 tons has di 酚A plastics. although it industrial use very large, is for 人 危害也不 small, research di 酚A会导致 inner separation 泌失调, has can can 引起癌症 and new 陈代谢紊乱导致 肥胖. 欧盟认 is di 酚A奶 bottle 会诱发 property 早熟, from 2011 year 3 month 2 day 起, prohibited production chemical material di 酚A 婴儿奶 bottle. therefore, in conditions lower most good need use PC材质 杯子装 hot water, more need in micro in add hot.
