Closed Cell NBR Rubber Foam Insulation
- The below 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 of 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.

Thickness Recommendations To Control Condensation In Pipe Insulation Of Cooling Lines
- 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.
