UL 1332 is a FEP perfluoroethylene propylene insulated high-temperature electronic wire produced according to the UL758 standard. It is a core wiring product for industrial high-temperature, precision electronics, and harsh working conditions. Zhejiang IRONFLON Wire&Cable Co., Ltd. has been deeply involved in the high-temperature cable industry for many years, strictly following UL certification standards and RoHS environmental standards to create a full range of UL 1332 wire. It adopts a composite structure of high-purity conductors and high-quality FEP insulation layer, perfectly adapting to a wide temperature range of -65 ℃ to 200 ℃ continuous working environment.


This UL 1332 standard wire has a rated voltage of 300V and excellent high-temperature resistance, flame retardancy, corrosion resistance, aging resistance, high insulation, and low loss characteristics. As a high-quality single core flexible cable, the wire has low eccentricity and uniform insulation wall thickness, effectively eliminating hidden dangers such as high-voltage breakdown, ignition, and leakage. At the same time, the wire has excellent flexibility, bending resistance, easy peeling and cutting, and strong processing adaptability. It is widely used in internal wiring, signal transmission, and circuit connection in fields such as home appliances, industrial control, new energy, medical, aerospace, and precision instruments. It is the preferred wire for high-temperature resistant wiring of high-end precision equipment.
Strong Processing Adaptability: The wire body is smooth and flexible, resistant to repeated bending, tensile and wear-resistant, easy to peel without cracking or peeling, convenient for cutting, terminal crimping, and welding processing, and compatible with automated equipment for mass production and processing, effectively improving customer production efficiency.
