PTFE 耐高溫260℃ PTFE 熱收縮套管
應(yīng)用
PTFE熱收縮套管由聚四氟乙烯(PTFE)材料制成,具有耐高溫(260℃)、耐腐蝕、高絕緣、機(jī)械強(qiáng)度佳等特性。其廣泛用于電子、計(jì)算機(jī)、電熱、航天、軍事、通訊等重要科技工業(yè),如微型變壓器等。通常用在液壓管道及其管道結(jié)合部位以保護(hù)管道不受腐蝕。由于它具有非常高的機(jī)械強(qiáng)度和極低的摩擦系數(shù),所以是保護(hù)受力軸和軸相關(guān)產(chǎn)品的理想產(chǎn)品。

PTFE 260℃ High-temperature PTFE Heat Shrinkable Tubing
Application
PTFE heat shrinkable tubing is made of PTFE with excellent high-temperature performance, chemical resistance, high insulation and excellent mechanical properties. Designed to provide insulation and mechanical protection in severe chemical and thermal environments. Widely used in electronic, aerospace, military and communication fields. Used to cover hydraulic hose and couplings to prevent contamination and corrosion. The high mechanical strength and extremely low coefficient of friction make it good for reducing damage to bearing shafts and similar applicationns.
Characteristics
v Shrink ratio: 1.7:1
v Excellent flammability
v High temperature resistant to 260℃
