高温热缩管
高温热缩管
n 应用 Application
由辐照交联特种含氟聚合物制成，应用于需要耐高温、耐磨擦的场合，具有优异的耐化学腐蚀和耐溶剂性能。保护线缆或被覆元器件免受机械损伤或化学腐蚀，用于线缆或元器件的标记保护，连接焊接处的绝缘和应力解除。
It is made of irradiation cross-linked special fluoropolymer with outstanding chemical and solvent resistance to be used for where to need high-temperature and abrasion resistance. To prevent wire and cable markers from mechanical and chemical abuse. It reliably protects electronic components while permitting their identification and inspection. Can also be used to provide insulation and strain relief of electrical connections and wire terminations, identification of wires, and packaging of components.
