The XFFR-15X25 is a halogen-free, flame-retardant heat-shrinkable tubing intended for repairing and rejacketing cables in environments requiring low toxicity. It features a 3:1 shrink ratio, with a minimum expanded inside diameter of 38.10 mm that shrinks to a maximum of 12.70 mm after heating. This tubing operates across a temperature range of -55°C to 110°C, resists moisture and fungus, and emits minimal toxic gases during combustion. It is ideal for use in enclosed areas such as tunnels, buildings, mass transit vehicles, and ships.
