SABIC(沙伯基礎(chǔ)創(chuàng)新塑料)LEXAN PC EXL4419是聚碳酸酯(PC)硅氧烷共聚物樹脂是9%玻璃纖維(GF)增強(qiáng)不透明注塑(IM)級,與GF增強(qiáng)的標(biāo)準(zhǔn)PC樹脂相比，這種介質(zhì)流樹脂具有更高的延展性、更好的釋放特性和優(yōu)異的加工性能，可以縮短IM循環(huán)時間,LEXAN EXL4419樹脂只能在不透明的顏色中使用，是一種很好的材料，適用于各種需要剛性和延展性的應(yīng)用場合。
PC是聚碳酸酯的簡稱，聚碳酸酯的英文是 Polycarbonate，簡稱PC工程塑料，PC材料其實(shí)就是我們所說的工程塑料中的一種，作為
被世界苑圍內(nèi)廣泛使用的材料，PC有著其自身的特性和優(yōu)缺點(diǎn)，PC是一種綜合性能優(yōu)良的非晶型熱望性樹脂，具有優(yōu)異的電絕性、延伸
性、尺寸穩(wěn)定性及耐化學(xué)腐蝕性，較高的強(qiáng)度、耐熱性和賽性;還具有自熄、阻燃、無毒、可著色等優(yōu)點(diǎn)，在你生活的各個角落都能見到
由于原材料浮動比較大，我們的每一款產(chǎn)品價格無法十分 地展示在客戶面前，因此我們也只是標(biāo)出一個象征性的價格，如果您對我們的產(chǎn)品非常感興趣，請聯(lián)系我們，我們將盡快給您報價。
本廠產(chǎn)品材料規(guī)格基本是按客戶要求定做的，加上原材料價格會有浮動，所以成品價格會有不同。展示的產(chǎn)品只是列舉了一些樣品，訂貨前請務(wù)必咨詢我們修改價格，或者直接致電我們！
