INSULFLEX – INSULATION TUBING & SHEET

Insulflex is a flexible and light weight elastomeric nitrile rubber material designed for thermal insulation. Insulflex insulation is generally black in colour, other colours are availble upon request. The product comes in tubing, roll and sheet form.The extruded flexible tubings are specially designed to fit the standard diameters of copper, steel and PVC pipings. Sheets are available in standards precut sizes or in rolls.

Use in:

Insulflex insulation is an expanded closed cell structure provides the ideal and most efficient vapour barrier for the prevention of condensation or frost formation on cooling systems, chilled water and refrigerant lines.

Insulflex insulation also prevent retards heat loss for hot water plumbing and heating, dual temperature piping and solar systems. It protects pipes by acting as a vibration damper and giving protection against corrosion by atmospheric and industrail environment.

Insulflex insulation with its inherent flexibility makes it ideally suited for the insulation of large surface area such as tanks, irregular shaped vessels, air-ducts and large diameter pipes.

NEW Launch Product

As a leader in closed cell insulation industry, Insulflex will continue and keep on developing new technology and equipment to fullfill market needs.

Think insulation, think Insulflex.

  • The above average physical properties are values obtained in accordance with accepted test methods.
  • At -40°C, Insulflex Closed Cell Insulation becomes hard and as temperature drops below -40°C will be increasingly brittle; however this hardening chracteristic does not affect thermal or water vapour permeability.
  • The Fire rating standard method od tests conducted under controlled laboratory conditions is a measure of a material to spread flame when compared to a known standard and is not intended to reflect hazards presented by this or any material under actual fire conditions.

  • Insulation for pipes of 10mm ID to 76mm IPS are available in tubing form with wall thickness of up to 25mm.
  • Insulation above 76mm IPS are in precut sheets and availble up to 38mm thickness.
  • Insulflex thickness recommended within the specified temperature ranges will control condensation on indoor piping under design conditions defined as follows:

    MILD
    Air-Conditioned and arid areas.
    NORMAL
    Maximum severity of most indoor conditions seldom exceed 29.4°C and 70% RH.
    SEVERE & EXTREMELY SEVERE
    Conditions of high humidity or poorly ventilated areas where temperature may be depressed below the ambient. Under conditions of high humidity, additional thickness of insulation may be required.
