EKOPRODUR 4540W/B is an aqueous, two-component system for producing polyurethane foams intended for thermal insulation of boilers, water heaters and tanks on periodic lines with increased mechanical resistance. The system can be processed with both low- and high-pressure foaming machines. The density of the foam in the finished product should be not less than 40 kg/m³.
EKOPRODUR 4540W/B system consists of two components. The first component (component A – EKOPRODUR 4540W/B) is a polyol mixture in a form of oily liquid with a straw to yellow colour and without suspensions. Component B (EKOPRODUR B) is a mixture of isocyanate in a form of a thick brown liquid which does not contain suspended suspensions. Due to the high sensitivity to moisture (high hygroscopicity) exposed to which it crystallizes rapidly.
An important fact is that EKOPRODUR 4540W/B does not contain foaming agents significantly depleting 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:
high efficiency on the production line,
low viscosity of components enables the processing on all types of foaming machines,
excellent operational properties, including increased mechanical resistance of the insulation,
the product is safe for the ozone layer,
quick demould time, depending on the size of a boiler (15-25 minutes)
high dimensional stability during operation,
possibility of producing boilers of different capacities (from 40 to 2000 dm3).
