Model: CB-TT
Application
Our PTFE non heat shrink tubing (product ID: CB-TT (L/S/T)), is made of polytetrafluoroethylene (PTFE) material and is widely used in electronics, computers, communications equipment and other fields because of its high temperature (260℃) resistance, corrosion resistance, high insulation and high strength. CB-TT has passed the American UL certified (certification number: E180908) and the compatibility test of the UL 1446 insulation system (DASH2B-5 System of PD GEORGE CO/RIPLEY RESIN)
Voltage grade: 150V/300V/600V
Temperature range: -80℃～200℃
