PBT耐化學(xué)3116|日本寶理
Properties and applications of PBT Engineering Plastics: Mechanical Properties: High Strength, fatigue resistance, dimensional stability, small creep (very little change at high temperature) heat aging resistance: Reinforced Ul temperature index is 120 ~ 140 °C (long-term outdoor aging is also very good) . SOLVENT RESISTANCE: No stress cracking. INSULATION: Excellent (moisture, high temperature can also maintain electrical stability, is the manufacture of electronic, electrical parts of the ideal material. FORMABILITY: General Equipment injection or extrusion. The mold temperature is lower than that of other engineering plastics due to its high crystallization rate and good fluidity. In the processing of thin-walled products, only a few seconds, on the large parts as long as 40-60 seconds. Sentence is too long, please supply a shorter sentence. POLYBUTYLENE terephthalate (PBT) is a kind of Thermoplastic used in different industries. It is usually mixed with some additives or other plastics. Depending on the proportion of the additives, it can be made to different specifications. PBT is widely used in electronic and electrical appliances, automobile parts, machinery and household products because of its heat resistance, weather resistance, drug resistance, good electrical properties, small water absorption and good luster.

物理特性
PBT是 堅(jiān)韌的工程熱塑材料之一,它是半結(jié)晶材料,有非常好的化學(xué)穩(wěn)定性、機(jī)械強(qiáng)度、電絕緣特性和熱穩(wěn)定性。這些材料在很廣的環(huán)境條件下都有很好的穩(wěn)定性。PBT吸濕特性很弱。非增強(qiáng)型PBT的張力強(qiáng)度為50MPa,玻璃添加劑型的PBT張力強(qiáng)度為170MPa。玻璃添加劑過多將導(dǎo)致材料變脆。PBT的結(jié)晶很迅速,這將導(dǎo)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(qū)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(diǎn)(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(zhuǎn)換溫度(glass trasitio temperature)在22℃到43℃之間。由于PBT的結(jié)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。
