Model: CYG-PFA
Material: PFA
Operating temperature: -65℃-260℃
Minimum full recovery temperature: 350℃
Shrink ratio: 1.3:1
Application
PFA has an excellent high-temperature performance, chemical resistance, high insulation and excellent mechanical properties. It is designed to provide insulation and mechanical protection in severe chemical and thermal environments. PFA heat shrink tubing is also widely used for areas where there are requirements for a superior clarity, flexibility, and a wider range of continuous operating temperatures.
Standard: AS23053/11
