Envase Tecnofoam poliuretano


Polyurethane foam for injection (applied density ±35 kg/m³ )

Tecnofoam I-2035 HFO is an injection polyurethane foam system for thermal insulation, it is specifically formulated to apply foam with applied density around 35 to 45 kg/m ³.  Its application must be carried out by the specific reactor equipment by mixing Tecnofoam I-2035 HFO (polyol side) and Tecnofoam G-2049.I (isocyanate side). The blowing agent is HFO gas.

Free of HFC


For use in the following situations:

  • it is specifically designed for thermal insulation, industry, farming or agricultural facilities.
  • filling industrial pipes and parts for thermal insulation
  • any application where is needed a thermal insulation behavior

  • It is an injection 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.
  • 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 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.
  • Contractors and applicators must comply with all applicable and appropriate guidelines for processing, handling guidelines and local rules and norms.


Metal drums of 250 kg for the isocyanate side, and 230 kg for the polyol side.


  • POLYOL COMPOUND: 6 months

Always store the drums before use at a temperature between 5 ºC and 35 ºC (41 ºF to 95 ºF),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 .

Very high temperatures can modify polyols, causing loss of the blowing agent, increasing consumption, and producing the swelling of the metallic drum. To avoid these last situations, it is recommended to let the drums for a while before use, in a cool and ventilated place.


In general, you should take the following factors:

  • the application of this polyurethane foam system  should be performed under the non-presence of moisture or water from the support stand on which to apply either at the time of application as a posteriori.
  • the substrate must be clean and free of dust, oils or greases.
  • The ideal drum temperature for processing Tecnofoam (Polyol and isocyanate) is 20 – 30°C.
  • 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 25 ~ 30 seconds.

APPLICATION REQUIREMENTS (injection equipment)

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: 35~45 ºC (95ºF to 113ºF)
  • Heater polyol temperature:±35~45ºC (95ºF to 113ºF)
  • Hose temperature:± 35~45 ºC (95ºF to 113ºF)
  • Pressure:>1200-1600 psi (75-110 bar)
  • Mixing ratio(recommended): GU-0087-3/GU-0087-4/GU-0087-5

These temperature and pressure parameters must be valued, ratified or slightly varied by the applicator, depending on the conditions of each climatic zone, weather situation or according to the specifications of the projection equipment. It is the responsibility of the owner / applicator of the equipment to keep it in perfect condition in order to maintain the correct mixing ratio of the two components that Tecnopol delivers separately, by periodically updating its maintenance controls. During the execution of the application, it may be necessary to correct these parameters according to changing external conditions, as well as to verify the correct operation of the machine (pressure and temperature).


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.
  • 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.
