pps阻燃管介紹
阻燃PPS--PPS熱(re)變(bian)形溫(wen)(wen)度(du)(du)(du)超過260℃，是目前使用(yong)溫(wen)(wen)度(du)(du)(du)高(gao)(gao)(gao)的熱(re)塑(su)性(xing)(xing)(xing)(xing)(xing)(xing)工程塑(su)料(liao)(liao)(liao)之一(yi)，長期(qi)使用(yong)溫(wen)(wen)度(du)(du)(du)為220~240℃，短(duan)時(shi)可(ke)達260℃。PPS材(cai)(cai)(cai)料(liao)(liao)(liao)耐化學(xue)性(xing)(xing)(xing)(xing)(xing)(xing)能：目前尚未(wei)發現可(ke)在200℃以(yi)下溶(rong)解(jie)PPS的溶(rong)劑(ji)，對無機酸、堿和鹽(yan)抵抗性(xing)(xing)(xing)(xing)(xing)(xing)極高(gao)(gao)(gao)。PPS材(cai)(cai)(cai)料(liao)(liao)(liao)電(dian)(dian)(dian)性(xing)(xing)(xing)(xing)(xing)(xing)能：在高(gao)(gao)(gao)溫(wen)(wen)、高(gao)(gao)(gao)濕、高(gao)(gao)(gao)頻率(lv)的環境中，具有很(hen)高(gao)(gao)(gao)的體積電(dian)(dian)(dian)阻率(lv)、表面電(dian)(dian)(dian)阻率(lv)、擊穿電(dian)(dian)(dian)壓，低的介電(dian)(dian)(dian)常數及介電(dian)(dian)(dian)損耗(hao)角正(zheng)切，是優(you)良(liang)的絕(jue)緣材(cai)(cai)(cai)料(liao)(liao)(liao)。經改性(xing)(xing)(xing)(xing)(xing)(xing)處理，也能制成具良(liang)好(hao)(hao)(hao)導電(dian)(dian)(dian)性(xing)(xing)(xing)(xing)(xing)(xing)能的高(gao)(gao)(gao)強材(cai)(cai)(cai)料(liao)(liao)(liao)。PPS材(cai)(cai)(cai)料(liao)(liao)(liao)力學(xue)性(xing)(xing)(xing)(xing)(xing)(xing)能：剛性(xing)(xing)(xing)(xing)(xing)(xing)極強，表面硬度(du)(du)(du)高(gao)(gao)(gao)，并(bing)具有優(you)異的耐蠕變(bian)性(xing)(xing)(xing)(xing)(xing)(xing)和耐疲(pi)勞(lao)性(xing)(xing)(xing)(xing)(xing)(xing)。PPS材(cai)(cai)(cai)料(liao)(liao)(liao)，PPS中文名稱叫(jiao)聚苯硫醚。它具有硬而脆(cui)、結晶度(du)(du)(du)高(gao)(gao)(gao)、難燃、熱(re)穩(wen)定性(xing)(xing)(xing)(xing)(xing)(xing)好(hao)(hao)(hao)、機械強度(du)(du)(du)較高(gao)(gao)(gao)、電(dian)(dian)(dian)性(xing)(xing)(xing)(xing)(xing)(xing)能優(you)良(liang)等優(you)點。PPS是工程塑(su)料(liao)(liao)(liao)中耐熱(re)性(xing)(xing)(xing)(xing)(xing)(xing)好(hao)(hao)(hao)的品種之一(yi)，熱(re)變(bian)形溫(wen)(wen)度(du)(du)(du)一(yi)般(ban)大于(yu)260度(du)(du)(du)、抗化學(xue)性(xing)(xing)(xing)(xing)(xing)(xing)僅(jin)次于(yu)聚四(si)氟乙烯，流(liu)動(dong)性(xing)(xing)(xing)(xing)(xing)(xing)僅(jin)次于(yu)尼龍(long)。此外，它還具有成型(xing)收(shou)縮率(lv)小（約0.08%），吸水率(lv)低（約0 .02%），防火性(xing)(xing)(xing)(xing)(xing)(xing)好(hao)(hao)(hao)、耐震動(dong)疲(pi)乏性(xing)(xing)(xing)(xing)(xing)(xing)好(hao)(hao)(hao)等優(you)點。
