PBI, CELAZOLE, Polybenzimidazole聚苯並咪唑, Black黑色
CELAZOLE PBI offers the highest temperature resistance and best mechanical property retention of all unfilled thermoplastics. Thanks to its unique property profile, CELAZOLE PBI might bring the ultimate solution when no other plastics material can. It is a very appealing material to high-tech industries such as semiconductor, aircraft and aerospace industries.
在所有無填充熱塑型塑膠中,PBI具有最耐高溫和最好的機械性能優點。在有離子污染的工作環境下,PBI是"乾淨的”而且不排氣(在水中除外)。這些特性使得這種材料在高科技工業如半導體和航空工業大顯身手。通常PBI用來製造要求嚴格的元件以降低維護維修費用,並且使用壽命最長
★Extremely high mix. Allowable service temperature in air(310℃ continuously, going up to 500℃ for short periods of time)空氣中最大允許工作溫度極高(可在310℃下持續工作,短時間可高達500℃)
★Excellent retention of mechanical strength, stiffness and creep resistance over a wide range of temperatures出色的機械強度和剛度保持力,使用溫度範圍大
★Extremely low coefficient of linear thermal expansion up to 250℃.極低的線膨脹係數,250℃工作溫度內
★Excellent wear and frictional behaviour.出色的耐摩和摩擦性能
★Inherent low flammability.固有的低可燃性
★Good electrical insulating and dielectric properties.優異的絕緣及介電特性
★high ionic purity level.處於離子污染的環境下的高純度

產品種類:PBI板,PBI棒
好料搜尋:高階工業塑膠,工程塑膠,耐高溫材料,耐熱變形,抗輻射
★PBI表現了適度的化學性能及抗水解性能。當處於沸水中或蒸氣條件下,材料將迅速變脆,性能下降
★PBI對機械加工來說硬度過大,當生產量大時,推薦使用鑽石刃的切削工具。所有邊角應倒圓角(R>1mm)或倒菱角以增加強度
★較高精度的機械加工應放在有乾燥劑的密封袋內存放以防吸水造成尺寸變化。當元件被突然放在高於200℃的溫度下使用時應事先乾燥以防熱衝擊變形
