The main pro-ecological aspiration of the TumbleAir company is to completely eliminate polyurethane foam from our products. The biggest threats connected with it appear during production, i.e.:

  • significant toxicity of some materials used to produce it – the appearance of toxic chemicals which destroy the ozone layer when reaching the stratosphere;

  • increased temperature of the process of foaming the polyurethanes and fast secretion of carbon dioxide result in a situation that certain by-products may be released into the air;

  • the emission of the substances present as pollutants of respective components;

The greatest threats from chemical substances appear:

  • when producing formed elements;

  • when producing blocs in a continuous manner;

  • during insulation works in closed rooms;

  • during hydrodynamic spraying in foam coating processes;

The dangers also occur on the workstations where the raw materials for foaming are prepared, and at the containers with respective reagents. Also, during the final stages there may appear exposure to toxic substances – while cutting the polyurethane foams with a hot wire there are produced toxic vapors, and the mechanic saw may produce the amount of heat sufficient to generate dangerous fumes. The glues that are commonly used to connect the elements contain the solvents which are often sprayed with a spray-gun, which causes a serious threat of fires. Polyurethane foams, just like all the organic materials, may be a source of fast-spreading fires. Foamed polyurethanes have low thermal resistance, lose mechanical strength at the temperature of 150-200°C, and decompose generating products of various composition and toxicity. The risk of poisoning is huge even with low amounts of burning foams. Spontaneous combustion of polyurethane foams may occur both during production and storage.

Another problem, of equal importance, is the recycling of post-use waste which is very difficult to reuse because it is non-degradable. The same goes for waste materials after foaming and technological waste materials, such as the foams from defective parts of products.

It should also be noted that there exist threats to the health of the employees producing the polyurethane foams.

  • threat of mould bursting

  • spillage of substrates due to damage to dosage system, and the possibility of contact between the skin and the hot foam (50-60°C).

The chemical substances generated in the production of polyurethane foams are characterized with chemical activity, consisting in reactions with the protein substance of the living tissues, thus causing their damage.
