Ekoprodur^® 2032B3/G Polyurethane system

The EKOPRODUR 2032B3 / G system consists of two components, i.e. component A, which is a polyol blend in the form of an oily, straw-coloured oil. The second component (B) is a mixture of aromatic polyisocyanates, which is a viscous liquid with a dark brown colour. Both system components do not contain any solid suspension. The distinguishing feature for this system is the foam density in the finished product, which should not be less than 45 kg / m3. In terms of processing, the product is quite versatile, as it can be processed both with low and high-pressure foaming machines. It is worth pointing out that materials based on this system retain good parametric stability and guarantee long service life, at temperatures up to 120 ° C.

Equally important is the fact that EKOPRODUR 2032B3 / G does not contain foaming agents that significantly deplete the ozone layer, according to the European Union regulations on the circulation and use of controlled substances in accordance with Regulation (EC) No. 1005/2009 of 16.IX.2009. In addition, the product has a Hygienic Certificate of the National Institute of Hygiene (PZH), which confirms that the product, when used in accordance with the manufacturer’s instructions, does not adversely affect health and the environment.

Main application advantages of the product:

• Possibility of direct pouring in the mould;
• Possibility to obtain a material with even distribution of density due to good levelling, allowing the precise filling of the form of a given element;
• The product optimizes production processes due to excellent adhesion to porous materials (thanks to the system’s ability to self-defoam);
• Production of material based on rigid polyurethane foam with a wide application range;

Mechanical properties of polyurethane foam made with the EKOPRODUR 2032B3 / G:

• Apparent density of core: ≥ 37 kg / m3
• Classification of the reaction to fire performance: F
• Short-term water absorption by partial immersion, WP ≤ 1.4 kg / m2
• Coefficient of thermal conductivity:
  • λmean, I: 0,024 W/(m·K)
• Compressive stress at 10% deformation, σ10 ≥ 180 kPa
• Temperature stability:
  • 80°C, over 24 h: l ≤ 4%, w ≤ 4%, t ≤ 1%
  • -30°C, over 48 h: l ≤ 2%, w ≤ 2%, t ≤ 0,5%
•  Adhesion of the foam, perpendicular to the ground: ≥ 200 kPa
• The content of closed cells: ≥ 90%

It should be borne in mind that the method of mixing and pouring the system into the mould should ensure uniform filling in such a way that the density of cut core parts in the finished element is not less than 35 kg / m3. It should be noted that the time needed for separating the element from the mould depends on the size and the temperature of the mould. The foamed system obtains full mechanical properties after 24-hour seasoning.
