Blockfoam

At our Tholen plant we use the very latest continuous production techniques to manufacture polyurethane (PUR) and polyisocyanurate (PIR) blockfoams. Computer controlled machines are used to process the blocks to create sheets and specials.

Polyurethane (PU) is a plastic invented during the 1930s. Polymers of various kinds are bound together chemically via urethane bonds using a polyaddition reaction. This results in a multiplicity of possibilities to modify the characteristics of the final product, such as rigidity, hardness, chemical resistance and so on. The further development of PU foam now offers almost unlimited possibilities.

Nestaan rigid blockfoam is used in sandwich panels, cold store and refrigeration, coach building, shipbuilding, technical insulation, polyester products and moulding, as well as innumerable other applications.

We are in a position to produce polyurethane in a wide range of dimensions, clearing the way to a great diversity of applications. For example we can deliver products in thicknesses ranging from 10 mm to 800 mm. As well as standard sizes we also deliver materials to client specifications. Further possibilities are created by the varying densities in which foam blocks can be produced, anything from 32 kg/m3 to 100 kg/m3. Finally the materials can be manufactured to meet different fire safety classifications.

Nestaan rigid blockfoam is characterized by its high insulation value combined with outstanding mechanical properties. Nestaan also continuously invest in new technology, allowing us to keep pace with our clients’ increasingly strict and demanding requirements.
