EKOPRODUR 3080B2 is intended for the production of structural elements of increased density with the use of rigid foam. It can be processed by means of high-pressure foaming machines. The obtained foam is characterized by increased fire resistance (flammability class E). Recommended density of the foam in a product is 40-60 kg/m3.
EKOPRODUR 3530B2 consists of two components, component POLY, which is a formula polyol mixture. The second component is ISO component, which is a dense mixture of aromatic polyisocyanates. Component ISO is a liquid with higher density and lower viscosity. Both components of the system do not contain suspensions.
In terms of processing, the product is quite versatile as it can be processed using both low- and high-pressure foaming machines. A characteristic feature of this system is the uniform density of the foam in the finished product, which should be at least 40 kg/m3. Insulation materials based on EKOPRODUR 3530B2 maintain good stability of parameters, even with continuous operation at temperatures up to -40°C and periodically up to 120°C.
An important fact is that EKOPRODUR 3530B2 does not contain foaming agents which significantly deplete the ozone layer. This is compliant with EU provisions on the marketing and use of controlled substances, according to Regulation (EC) no. 1005/2009 dated 16 September 2009. Moreover, the product has a Hygienic Certificate issued by the National Institute of Hygiene (PZH), which proves that the product used according to the manufacturer’s instructions has no negative impact on health and the environment.
Main application advantages of the product:
Reduced flammability confirmed by certificates in the shipbuilding industry;
Possibility of pouring directly to the mold or filling in empty spaces;
Possibility of the production of insulating material with even density distribution thanks to good flow properties allowing for thorough filling of the mold of the given element;
Production of the material based on rigid polyurethane foam with a wide application range;
Mechanical properties of the foam:
Apparent density of the core: 36 kg/m3 (PN-EN 1602:2013-07)
Time of demolding of the foamed EKOPRODUR 3530B2 system depends on the size of a fitting (element) and temperature of the mold. The foam achieves its full mechanical properties after 24-hour seasoning. It is worth bearing in mind that in case of aluminum or stainless steel cladding it may be necessary to prepare the substrate mechanically or chemically to increase adhesion.
