Shanghai Daoqin Plastics Co., Ltd.

        消费者都喜欢 transparent plastics product. transparent degree high or transparent in belt/tape has color material has polypropylene (PP) PP, transparent ABS, transparent nylon, polysulfone (PSU) and polyimide (PI) type. transparent degree high plastics has PMMA, GPPS, PC and copolymer polyester (例如Tritan) and other. remove comparison transparent degree outer, also need 考虑塑枓 product heat resistant, machine strong/high degree and resistant property and other requirements. more important is, if material food, also need safety property. Tritan and PC is comparison 突出 两 types material, remove has high transparent property, also 异常坚 solid resistant use, 也经常 in food use tool in by using/adopting, how to selection need it 们各自 features.

        我们 summary below/following several selection transparent plastics product need features comparison, specific lower:

         physical properties comparison

         in transparent degree 方面, transparent degree high plastics Tritan and PC两者都达 to color, full transparent, 但Tritan透 rate high, products more add 晶莹剔透.

         in resistant chemical property 方面, Tritan performance more 佳. PC in use agent rear transparent degree 就会迅 speed decline, causes in 于PC resistant property can good. PC for/regarding alkali property material and more 数油脂都显 脆 low 而敏感, 一经接触, its 各方面 property can obvious poor 化. 而Tritan in chemical resistance can upper has obvious advantages. if 进行洗碗 machine testing, PC往往 in 数次 洗碗 machine ring rear has cracks 出现, 而Tritan则 can 经历数百次循 ring milli loss.

         in strong/high degree 方面, PC and Tritan impact strong/high degree versus upper lower, in solid property upper has same can property.

         in heat resistant property 方面, PC则 has obvious advantages. PC heat deflection temperature (HDT) to 137℃, same conditions lower Tritan most high has 109℃.

         safety property factors

        Tritan and PC两者 more important in is has BPA(di 酚A). PC is 以BPA is main/primary raw materials made formed material, 而Tritan完 full has BPA. BPA is low material 质, material 实验发现 its tool has 显 雌 property 激素效应, make is very low agent amount, tool has 一定 胚胎毒 property and property. 调查也发现 long 期暴露于BPA ring lower obvious has to loss 害. although has table/sheet 明PC container 迁移出 micro amount BPA for has effect/influence. and is 证据不足也不 can 打消人们 for PC in safety property 方面 顾虑, 毕竟PC products temperature degree time 变化会不断累积 析出BPA. therefore 各国政府 is food safety, rate in use product upper use 含BPA material, rear 欧美各国 ban scope/range day expand large. 而Tritan in transparent property and strong/high degree 方面足够媲美PC, full 不含BPA, in food contact application, year 取代 不 small PC market 份额.

        消费者 how to selection?

        如今欧 USA for food contact product has BPA ban, in export product material selection 当然首选Tritan. 至于国 inner market, China prohibited in product upper use BPA材 material, therefore PC also in other food container market upper relatively low price maintain versus 当 份额. for/regarding 关心健康 消费者, also 会避开BPA而 selection Tritan made formed product.
