★High quality material: Pipe Insulation is made of soft and Elastomeric foam material, Fire Resistant, flame retardant, high temperature resistant, Waterproof，Antifreeze，closed cell structure, smooth surface of insulation material, high elasticity, soft texture and good anti-resonance effect. ★Excellent thermal insulation performance: Foam Tube adopts high-density closed structure, low thermal conductivity, stable temperature, with the function of thermal insulation. Therefore, even if it is cold outside, it will not affect the inside of the water pipe. ★Rubber Tubular Good flame retardant performance: when burned by fire, the insulation material will not melt and lead to low smoke and will not spread the flame, thus ensuring safety in use; the material is determined to be non-combustible and the temperature range for use is -50°C to 110°C. ★Size: inner diameter 6mm (1/4")-110mm (4-1/3"), thickness 9mm (3/8")/15mm (3/5")/20mm (7/9"), length 1.7 m (5.6 ft)/1.8 m (6 ft) ★Easy to install, easy to use: no need to install other auxiliary layers, just cut and bond, easy to install. It is suitable for the protection of outdoor pipes against freezing, gas pipes, indoor and outdoor water pipes, air conditioning delivery pipes and solar pipes. It can be better used in industry and construction.
