PBT美國沙伯基礎420SE0(基礎創新中國)

PBT是堅韌的工程熱塑材料之一，它是半結晶材料，有非常好的化學穩定性、機械強度、電絕緣特性和熱穩定性。這些材料在很廣的環境條件下都有很好的穩定性。PBT吸濕特性很弱。非增強型PBT的張力強度為50MPa，玻璃添加劑型的PBT張力強度為170MPa。玻璃添加劑過多將導致材料變脆。PBT的結晶很迅速，這將導致因冷卻不均勻而造成彎曲變形。對于有玻璃添加劑類型的材料，流程方向的收縮率可以減小，但與流程垂直方向的收縮率基本上和普通材料沒有區別。一般材料收縮率在1.5%~2.8%之間。含30%玻璃添加劑的材料收縮0.3%~1.6%之間。熔點（225℃）和高溫變形溫度都比PET材料要低。維卡軟化溫度大約為170℃。玻璃化轉換溫度（glass trasitio temperature）在22℃到43℃之間。由于PBT的結晶速度很高，因此它的粘性很低，塑件加工的周期時間一般也較低。

PBT機械性能：

1、非增強型品級(純PBT)有優異的沖擊韌性，抗脆性能力強。

2、經玻璃纖維增強後的PBT其力學性能的各種強度都可成倍增長，熱變形溫度得到很大的提高。而且比同樣條件下的MPPO、POM、PC的各種強度都好;

3、抗彎強度更是隨纖維的含量而大幅度提高。且韌性較好又耐疲勞。

4、相較于非增強的塑膠，玻璃纖維增強的PBT呈現出增加二到叁倍的抗拉強度，抗彎強度，壓縮強度和剛性。
