Envase Tecnofoam poliuretano


Polyurethane foam for injection (applied density 12~18 kg/m³ )

Injection polyurethane foam system for thermal insulation, is specifically formulated to apply foam with applied density around (12~18 kg/m³). Its application must be carried out by the specific reactor equipment by mixing Tecnofoam I-2008 (polyol side) and Tecnofoam G-2049.I (isocyanate side). The blowing agent is water.

water baseFree of HFC



For use in the following situations:

  • It is specifically designed for thermal insulation, industry, farming or agricultural facilities.
  • In applications ceilings, interior chambers facade ventilated facades.

NOTE: For other applications / situations, please, consult our technical department

application method specific equipment


  • It is an open cell foam system for thermal and acoustic insulatinon, easy to apply and to protect all the internal surfaces of the building.
  • The application and training is done by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar.
  • The blowing agent is water. It is free from harmful to the ozone layer, so do not promote the greenhouse effect (NOT contain HFCs, HCFCs, VOCs, etc ...); it does not emit any substance to the environment once installed. The applied system is 100% recyclable by mechanical means friendly to the environment. No gas collection for recycling and/or destruction is required.
  • The properties of the polyurethane foam system TECNOFOAM I-2008 allow it to adhere to any surface such as concrete, ceramic, metal, polyurethane foam, wood, acrylic paints (checking the situation of areas recommended).
  • It forms a continuous coat without joints preventing the formation of "heat bridges" and providing an optimum thermal insulation surface with high thermal insulation parameters.
  • The thermal conductivity coefficient remains unchanged from the application and along with the product life.


Metal drums of 250 kg for the isocyanate side, and 215 kg for the polyol side


  • POLYOL COMPOUND: 4 months (we recommend stirring before use and also during the application)

Always store the drums before use at a temperature between 5 ºC and 35 ºC, always in dry areas, without the possibility of moisture entering, and without direct contact with the sun or heat sources, otherwise they may be affected its reactivity and performance. Low ambiance temperature increase the viscosity of the polyol, which makes it difficult to mix and apply, and can generate crystallization in the isocyanate, which can cause its mixing ratio to vary and the consequent internal problems in the mixing and application equipment.


In general, you should take the following factors:

  • The application of polyurethane foam system TECNOFOAM I-2008 should be performed under non-presence of moisture or water from the support stand on which to apply either at the time of application as a posteriori.
  • The ideal drum temperature for processing Tecnofoam (Polyol and isocyanate) is 20 – 30°C.
  • The substrate must be clean and free of dust
  • Injecting the mixed product through the reactor equipment, through perforations located on the element to be insulated.
  • Consider that the time of expansion of the two components, once mixed is one 45 ~ 50 seconds.
  • Repeat this action as many times as necessary to fill the entire element.


For the formation, it is necessary to mix the two initial liquid components, isocyanates and polyols with our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar (proper maintenance and cleaning it is recommended). 

The general parameters for this material will be the following:

  • Heater isocyanate temperature: 30~35 ºC
  • Heater polyol temperature: 50~60ºC
  • Hose temperature: 40~45 ºC
  • Pressure: 1.200 - 1.600 psi / 75 - 110 bar (the exact pressure depends on the kind of needs of the application)
  • Mixing ratio(recommended): GU-0087-3/GU-0087-4/GU-0087-5

These temperature and pressure parameters have to be valued, ratified, or be varied by the applicator, depending on the conditions of each climate zone, weather situation, or projection equipment specifications.


These safety recommendations for handling, are necessary for the implementation process as well as in the pre-and-post, on exposure to the loading machinery.

  • Respiratory Protection: When handling or spraying use an air-purifying respirator.
  • Skin protection: Use rubber gloves, remove immediately after contamination. Wear clean body-covering. Wash thoroughly with soap and water after work and before eating, drinking, or smoking.
  • Eye / Face: Wear safety goggles to prevent splashing and exposure to particles in the air.
  • Waste: Waste generation should be avoided or minimized.
  • Incinerate under controlled conditions in accordance with local laws and national regulations.
  • It is a mandatory a good ventilation system when you applied in closed areas. For ventilation, you should use a fan or similar device with sufficient power to renew air room.
  • Re-occupancy of the work site without respiratory equipment is minimum 24 hours providing the correct ventilation for the area sprayed.

Contractors and applicators must comply with all applicable and appropriate guidelines for storage and safety guidelines. Anyway, consult the material and safety data sheet of the products of the system.
