Insutek KFSC series of Fiber Optic splice closure heat shrinkable tube, is kind of specially designed product which suitable for sealing communication optical cable splice box, enclosures, overhead, directly buried communication cable.
It consists of: Outer layer medium wall heat shrink tube and inner layer of adhesive. The outer layer of tubing can provide reliable external protection, and the high performance inner hot melt adhesive can provide reliable waterproof performance , and prevent gas leakage in the splice box.
Features:
- Anti-UV, waterproof, Corrosion resistance, Resistance to mechanical damage
- Hot melt adhesive prevents the leakage of the filling gas of the optical fiber connection box, which can pass 10 times of High-Low Temperature cycling test.
- The surface of the product can be sprayed with color-changing paint, which is convenient for heat shrink operation instructions
- Operating Temperature: -55 to +110℃, Minimum Shrink Temperature: 125℃
- Shrink Ratio: 4:1
- Color-changing paint: Begin to turn color at 220℃
