The Superior Insulation Foam
  • Phenotherm Phenolic Foam is a rigid cellular foam insulation material with a substantially closed cell structure, whose polymer structure is made primarily from the poly-condensation of phenol, its homologues and/or derivatives with aldehydes and ketones.
  • Phenotherm has various distinct properties that makes it better than conventional insulation materials.
  • Lower K value (K Value = 0.017W/mK) - that means exceptionally low thermal conductivity.
  • Wide service range for diverse insulation applications
  • Cost-effective because lower thermal conductivity facilitates usage of lesser thickness of Phenotherm for the same level of insulation.
  • Superior fire and insulation properties enable phenotherm to be used as a direct replacement for conventional insulation materials such as expanded polystyrene, rigid urethane foam (polyurethane and polyisocyanurate), polyethylene foam, resin-bonded glass wool, etc.
  • A wide service temperature range between -196 C to + 130 C makes Phenotherm ideal for low temperature and cryogenic applications. It can be effectively used on LSHS, fuel oil, low pressure steam and hot water lines.
  • Low water absorption is a key feature of Phenotherm. A high closed cell content of upto 95% results in very low water vapour transmission and reduces condensation.
  • Phenotherm is tested as per BS 4370 for mechanical properties and conforms to BS 3927.
  • Phenotherm assures longer life as it is unaffected by most aromatic and aliphatic solvents.
  • Odourless and does not absorb colour.
  • Rodent / insect proof and being mildly antiseptic resists fungal and bacterial growth.
  • Corrosion and chemical resistance is another strength. Phenotherm resists organic solvents and chemicals. Being non-abrasive and hydrophobic, it does not corrode metal.
  • Phenotherm has anti-static properties. It is an electrical insulator and in case of friction does not generate static electricity or sparks.
  • Phenotherm is workable, easy to install and can be cut and shaped to any size with handtools.
  • Under-deck and over-deck (roof) insulation
  • Pipe and duct insulation
  • Suspended ceilings and partitioning for commercial complexes, residential buildings and hospitals.
  • Insulation of vessels, pipelines in petrochemical, fertilizer, chemical and pharmaceutical plants and in refineries.
  • Insulation of cold storage and refrigerated rooms.
  • Life-saving equipment such as life jackets, buoyancy block and other marine equipment
  • Insulation of refrigerated rail, surface and marine equipment and containers.
  • Insulation of high-altitude shelters
  • Ship insulation.
