KY175   175℃High-Temperature KYNAR Heat Shrinkable Tubing

Application

    KY175 is made of special irradiation cross-linked fluoropolymer PVDF with outstanding chemical and solvent resistance and high-temperature performance. It is tough, semi-rigid, very thin wall especially suitable for applications requiring high-temperature performance, outstanding abrasion resistance and cut-through resistance, or superior chemical and solvent properties. It is also used for insulation and strain relief of soldered joints, identification and inspection of covered components.

Characteristics

v Shrink ratio: 2:1

v Semi-rigid, very thin wall insulation

v Excellent flammability

v High temperature resistant to 175℃

v Good toughness, excellent abrasion resistance, physical and chemical properties.

v ROHS and REACH compliant

Operating Temperature Range

v Operating temperature:  -55℃~175℃

v Minimum shrink temperature:  155℃

v Minimum fully recovery temperature:  175℃

Approvals

v SAE AMS-DTL-23053/8
