PS is a low cost, resilient, and energy efficient method for pipe insulation applications ranging between temperatures of -110°C and 74°C. EPS comes in standard sizes and it can be cut to specification to meet your tank and vessel requirements. EPS insulation aids in process control, conservation of energy, and personal/equipment protection.


  • Low k-factors for your insulation needs.
  • Lightweight and durable.
  • No long-term R-value loss or thermal drift.
  • No CFC, HCFC, HFC, or formaldehyde.
  • Easy to fabricate.
  • Superior ingress resistance to moisture.
  • Cost effective thermal control is a very high priority in tank and vessel insulation.
  • Foam-Control EPS pipe insulation comes in a wide range of densities necessary to provide energy efficiency, structural integrity, cost effectiveness, and its proven to do so.

Technical Data

  • Tanks
  • Vessels
  • Resistant to vibration.
  • Low mass.
  • Thermally efficient.
  • Recyclable.
  • CFC and HCFC free, physiologically and chemically harmless.
  • Resistant to aging, mildew, bacteria and rot.
  • Easily cut and worked (finetoothed saw and conventional hand tools).
  • Easily bonded.
  • Ensure adhesive is compatible with EPS
  • Easily painted using high quality acrylic PVA applied by brush or spray
  • Flame retardant EPS distinctly reduces the flammability and the spread of flame on the surface of foamed articles. This productis self-extinguishing as soon as the ignition source is removed Fire Retardant FR grade (Styrene unfaced) has obtained a B/B1/2/H&V with & without sprinklers when tested in accordance with SANS 428
  • EPS is not known as a good sound absorbing product due to its closed cell structure and low density. Insulpro offers a range of alternative acoustical insulation products if required.
  • CFC free, recyclable, and does not decompose into harmful substances.
  • Polytec does not provide sustenance for rodents
  • Densities of 15, 24 and 30 kg/m³
  • Thermal conductivity at 10°C ranging from 0.033 to 0.038 W/m.K
  • Hardness of 70, 110 and 200kPa
  • Temperature limitations -110 to 70°C
  • CFC and HCFC free, physiologically and chemically harmless
  • Easily painted using high quality acrylic PVA applied by brush or spray
