阻燃性可達(dá)UL94 V–0級(jí)。通常，將溴化合物、氯化物、磷化物以及Sb2O3作為阻燃劑。多數(shù)阻燃等級(jí)PBT采用十溴聯(lián)苯醚以及Sb2O3，其阻燃性能未實(shí)現(xiàn)高阻燃性，在燃燒時(shí)會(huì)產(chǎn)生煙霧并存在滴落，因此，相關(guān)公司致力于研究采用齊聚物以及高分子量聚合物型阻燃劑對(duì)PBT進(jìn)行阻燃改性。工程塑料可以作為良好的結(jié)構(gòu)材料。</p><div

style="text-indent:25px">PBT工程塑料有顯著的熔點(diǎn)，當(dāng)溫度升至熔點(diǎn)以上時(shí)，活動(dòng)性會(huì)突然添加，尤要引起留意。PBT成型加工范圍較窄，冷卻時(shí)結(jié)晶很快，加之活動(dòng)性好，特別適于快速打針。PBT了有較大的縮短率及其縮短范圍，且在不同方向的縮短率差別較其他塑料更顯著。PBT對(duì)缺口、尖角的反應(yīng)很靈敏，在這些方位易呈現(xiàn)應(yīng)力會(huì)集，使承載才能大為下降，在受力或受沖擊時(shí)易發(fā)生破裂，因而在規(guī)劃塑件時(shí)應(yīng)留意這一點(diǎn)，一切轉(zhuǎn)角處，特別是內(nèi)部轉(zhuǎn)角應(yīng)盡量采用圓弧過渡。純PBT的伸長率可達(dá)200%，因而帶有較小洼陷的制品可以從模具上強(qiáng)制脫模。但用玻纖或填料填充后，其伸長率大為下降，在制品中如有洼陷就不能實(shí)施強(qiáng)制脫模。太倉工程塑料批發(fā)價(jià)</p></p><br
