应用
PTFE热收缩套管由聚四氟乙烯（PTFE）材料制成，具有耐高温（260℃）、耐腐蚀、高绝缘、机械强度佳等特性。其广泛用于电子、计算机、电热、航天、军事、通讯等重要科技工业，如微型变压器等。通常用在液压管道及其管道结合部位以保护管道不受腐蚀。由于它具有非常高的机械强度和极低的摩擦系数，所以是保护受力轴和轴相关产品的理想产品。

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.
