High Temperature Heat Shrinkable Tube
Kynar 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.
