260 degree heat-shrinkable tube oil-resistant acid-alkali polytetrafluoroethylene PTFE heat-shrinkable casing tube
PTFE heat shrink tube 1.7: 1 2:1 4:1
PTFE heat shrink tube is a highly flame retardant heat shrinkable tubing manufactured from modified PTFE .It Provides insulation and mechanical protection in severe chemical and thermal environments. Thin wall, high shrink ratio, flexible and transparent Major uses: electrical insulation, protection of electronic components, covering of hydraulic hose and couplings, prevention against contamination and corrosion High mechanical strength and extremely low coefficient of friction make it ideal for reducing damage to bearing shafts etc
Features
Continuous operating temperature: -65°C~260°C
Resistant to corrosion, strong acid, strong base, chemical reagents, and oil etc
Excellent Dielectric Insulation Properties
Excellent electrical performance that does not change with the temperature and frequency
Excellent mechanical performance, shock proof, high elasticity
Ultra low friction coefficient, highly flame retardant
