在現(xiàn)代工業(yè)里，雙酚A應(yīng)用是非常普遍的，從礦泉水瓶、醫(yī)療器械到食品包裝的內(nèi)里，都有它的身影。雖然它工業(yè)用處很大，但是對(duì)人的危害也不小，據(jù)研究雙酚A會(huì)導(dǎo)致內(nèi)分泌失調(diào)，甚至有可能引起和新陳代謝紊亂導(dǎo)致的肥胖。歐盟認(rèn)為含雙酚A奶瓶會(huì)誘發(fā)性早熟，由于雙酚A存在對(duì)身體危害的可能性，2010年加拿大成為個(gè)禁止雙酚A上架的國(guó)家；2011年3月歐盟同樣采取措施；但其實(shí)直到現(xiàn)在，也沒(méi)有直接的證據(jù)支持雙酚A對(duì)嬰兒有重大食品安全問(wèn)題。也就是說(shuō)，我們既不能確定雙酚A無(wú)害，也不能確定它有害。但對(duì)于食品安全，尤其是嬰幼兒的食品安全，我們需要采取更加保守和謹(jǐn)慎的態(tài)度！因此，在條件允許下比較好不要用PC材質(zhì)的杯子裝熱水，更不要放置在微波爐中加熱！UTPE彈性體平臺(tái)**補(bǔ)充科普相關(guān)知識(shí)：正規(guī)塑料瓶的底部都有一個(gè)帶箭頭的三角形，三角形里面有一個(gè)數(shù)字，指代的是該瓶子包含的成分和該成分對(duì)人體健康的影響。關(guān)注公眾號(hào)“UTPE彈性體門(mén)戶”，了解更多的材料安全知識(shí)，對(duì)接更多的彈性體材料供求信息、技術(shù)資料和配方，更多訂單和生意，可以讓你一手掌握！用戶評(píng)論淡薄那，裝常溫的水可以不？0rezo樓主我買(mǎi)了個(gè)杯子，杯子是玻璃的，蓋子是塑料的。</p><p>

曾經(jīng)材料行業(yè)的幾篇關(guān)于pc材料杯子安全性的文章，引起了眾多網(wǎng)友的恐慌，很多人都查閱了一堆資料，但是都得不到一個(gè)詳細(xì)的解釋，現(xiàn)在關(guān)于pc材料的杯子裝開(kāi)水有沒(méi)有毒的疑惑，UTPE彈性體平臺(tái)**在線給大家科普一下。首先認(rèn)識(shí)一下pc材料是什么？PC就是聚碳酸酯，是比較常見(jiàn)的塑料材料之一，材料其實(shí)本身是無(wú)毒的，一般用于制造奶瓶、太空杯等，但因其含有雙酚A而備受爭(zhēng)議。理論上只要在制作PC的過(guò)程中雙酚A完全轉(zhuǎn)化成塑料結(jié)構(gòu)，制品就不會(huì)存在雙酚A，也就也就無(wú)毒的，對(duì)健康沒(méi)有威脅。假若有少量雙酚A沒(méi)有轉(zhuǎn)化成PC的塑料結(jié)構(gòu)，則可能會(huì)滲入食物或飲品中威脅使用者，特別是青少年的健康安全。pc材料的杯子裝開(kāi)水一般是沒(méi)問(wèn)題的，為什么？因?yàn)橐话愕腜C材質(zhì)的塑料杯可以耐-45℃-135℃的溫度，開(kāi)水一般都在這個(gè)區(qū)間內(nèi)，所以比較安全。但這是材料的物理性能，只是說(shuō)這種材料在這種溫度下使用是不會(huì)開(kāi)裂熔化。但是當(dāng)我們從食品安全角度出發(fā)會(huì)發(fā)現(xiàn)，隨著溫度愈高，PC中殘留的雙酚A釋放量會(huì)愈多，而且速度也愈快，所以PC之所以會(huì)存在健康威脅是因?yàn)樵诟邷貢r(shí)它會(huì)釋放雙酚A，那么這讓人“聞之色變”的雙酚A到底是何方神圣呢?雙酚A(BPA)在工業(yè)上常被用來(lái)合成PC和環(huán)氧樹(shù)脂等材料。PC

pc材料就是聚碳酸酯材料，Polycarbonate，是一種無(wú)色透明的無(wú)定性熱塑性材料。機(jī)械強(qiáng)度非常高，聚碳酸酯無(wú)色透明，耐熱，抗沖擊，阻燃，不需要添加劑就具有UL94V-0級(jí)阻燃性能。PVC材料就是聚氯乙烯材料，是目前產(chǎn)量居第二位的通用塑料，也是用途廣的塑料，PVC本身也是無(wú)色透明的硬質(zhì)材料，但比PC脆的多，透明度也不如PC，其它的機(jī)械性能也與PC相差很遠(yuǎn)。但PVC可以加入很多增塑劑，加入后就可以做成軟質(zhì)PVC。所謂硬PVC就是100公斤PVC樹(shù)脂粉里增塑劑添加量少于5公斤的聚氯乙烯PVC塑料，象建筑用下水管、落水管、塑鋼窗、之類(lèi)的都是屬于硬PVC。增塑劑添加量大于5公斤叫半硬PVC，大于25公斤叫軟PVC，象普通電線外皮、一次性輸液管、一些充氣玩具、軟門(mén)簾、超市賣(mài)的那種叫軟玻璃的透明塑料桌墊等都是軟PVC的。PVC還可以任意著色，做成各種透明不透明的彩色制品，所以PVC是目前用途范圍廣的塑料，價(jià)格只有PC的1/2到1/4左右。3.工業(yè)合成PC是雙酚義型、結(jié)晶度，而無(wú)鹵環(huán)保磷系阻燃劑會(huì)明顯降低PC的熱變形溫度和沖擊強(qiáng)度，因此比較適宜的是有機(jī)硅系阻劑是以聚氯乙烯樹(shù)脂為主要原料，加入適量的抗老化劑、改性劑等，被運(yùn)用于生產(chǎn)和生活中。譬如PVC水管、PVC塑料門(mén)窗。鹽城便宜的PC市場(chǎng)</p><p
