Low thermal conductivity Closed-cell foam structure High elasticity Highly elastic and flexible rubber tubing reduces the vibration and resonance of chilled and hot water piping during use Meet the most stringent requirement of fire retardant Long term temperature tolerance: (-50 degrees to 110 degrees C) Good elasticity, Good flexibility,long-term good sealing Long life: 10-30 years
Kingflex insulation tube is generally black in color, other colors are available upon request. The product comes in tube, roll and sheet form. The extruded flexible tube are specially designed to fit the standard diameters of copper, steel and PVC piping. Sheets are available in standards precut sizes or in rolls. Kingflex rubber foam material is available for different facing which are FSK Alu Foil, Adhesive Kraft, etc. Technical Data Sheet
