　通過時間不少于0.1s.另外(wai)，電伴(ban)(ban)熱(re)外(wai)護套除(chu)以上基(ji)本要(yao)求外(wai)，還應考慮(lv)其柔軟性，一般(ban)彎曲(qu)半徑是(shi)其直徑的5倍(bei)。耐熱(re)性和抗老化性，有些場合例如(ru)長期暴曬，需(xu)考慮(lv)防(fang)紫(zi)外(wai)線。潮濕容(rong)易滋(zi)生霉菌(jun)或者腐蝕(shi)區，需(xu)考慮(lv)電伴(ban)(ban)熱(re)外(wai)部防(fang)腐蝕(shi)性。

　　自限溫電伴熱外護套材質的選擇，因為這直接影響著電伴熱的使用安全性，采用改良性聚烯烴。具體有105 C.阻燃聚烯烴135 *c、含氟聚烯烴180 C、全氟材2051C。具有防爆防護阻燃功能，可使用于一般，防爆，腐蝕，危險19。可耐一60 *c，安全環保。
