铁氟龙(PTFE)热收缩管/铁氟龙(PTFE)套管具有防油、耐酸碱、防腐蚀性能。广泛用于电气、机械、印刷、石油化工等工业。
特点:★耐高温,半透明,阻燃,半硬质;收缩倍率:2:1(收缩型) ;使用温度:-55℃~260℃;标准颜色:半透明。
PTFE is high temperature, highly flame retardant PTFE tubing with excellent chemical resistance, It Is designed to provide insulation and mechanical protection in severe chemical and thermal environments. Used to cover hydraulic hose and couplings to prevent contamination and corrosion. The high mechanical strength and extremely low coefficient of friction make it ideal for reducing damage to bearing shafts and similar applications. Standard Color: Clear
Characteristics: ★Shrink ratio:2:1;Operating Temperature: -55℃~260℃;
