EKOPRODUR PM4032 is a polyurethane (PUR) system consisting of two components. The first of them (component A) is a polyol mixture in a form of oily liquid with a straw to yellow colour, without suspensions. The second component (component B) is a mixture of aromatic polyisocyanates. This component is a brown liquid without suspension. It has an outstanding sensitivity to moisture, exposed to which it quickly crystallizes.
EKOPRODUR PM4032 is a cast system designed for preparing the rigid foam of closed-cell structure and self-extinguishing properties. Due to the excellent flow and high thermal resistance, the system is dedicated to the production of insulation boards and panels of large size. Temperature resistance of the foamed system is in the range of -24°C to even +100°C. At the same time the system can be poured in moulds and used for filling gaps. The system has exceptionally prolonged reaction times, which means it can be processed both manually and by professional foaming machines of low and high pressure. The foamed system has a density in the product of at least 42 kg/m 3 (calculated as a ratio of system weight [kg] to the total volume of the mould [m3]). Component A is prone to slow delamination, so it should be mixed thoroughly before usage.
An important fact is that EKOPRODUR PM4032 does not contain foaming agents that significantly deplete the ozone layer, which is pursuant to EU regulations on the sale and use of controlled substances according to Regulation (EC) No. 1005/2009 of 16 September 2009. In addition, the product has a Hygienic Certificate issued by the National Institute of Hygiene (PZH), which confirms that the product used in accordance with manufacturer’s instructions does not adversely affect health and the environment.
Main application advantages of the product:
Possibility of obtaining an insulating material with a low thermal conductivity coefficient (λ), which allows to reduce the thickness of the insulation and as a consequence to decrease the use of material;
Possibility of obtaining an insulating material even by manual processing;
Production of insulating material based on a rigid (hard) polyurethane foam with a wide range of application;
Production of an insulating material with increased temperature resistance (from -24°C up to +100°C);
Production of insulating material having a uniform density distribution thanks to the good flow of the system.
Production of insulating material with low water-absorption properties;
Mechanical properties of the foam system:
apparent density of the core: 36 ± 2 kg/m3
Compressive resistance: 190 kPa
Water absorption after 24 hours: 1.1% v/v
Thermal conductivity coefficient at 10°C: 0.024 W/(m·K)
Closed cell content: ≥ 90%
Flammability class: F
Temperature resistance: -24 ÷ 100°C
+100°C, 24h: max. 0.5%
-24°C, 48h: max. 1% -0.3%
It should be noted that the aluminium or stainless steel claddings may require a mechanically or chemically prepared substrate to improve adhesion. A method used for mixing and pouring the system into the mould should ensure uniform filling. Demould time depends on the moulder size and mould temperature. It should be also remembered that the polyurethane foam achieves full mechanical properties after approx. 24 hours conditioning.
