3:1 SHRINK RATIO, HIGH
TEMPERATURE, CHEMICAL RESISTANT, PVF2 TUBING
Applications
GSHS-3675
is semi-rigid, flame retardant, heat shrinkable polyvinylidene fluoride (PVF2) tube for applications requiring outstanding abrasion
and cut-through resistance. It reliably
protects wires, solder joints, terminals, connections and components from most
industrial fuels, solvents and chemicals.
Features
¬
Shrink ratio: 67% or
more in the radial direction, 5% or less in the axial direction
¬ Continuous operating temperature: - 55°C to 175°C
¬ Flammability: UL VW-1, CSA OFT
¬ Excellent electrical properties
¬
High resistance to chemicals and oils
Standard
¬ UL 224 (File Number: E84393)
¬ MIL-DTL-23053/8
