Since the early 1980s, the use of new building materials has increased considerably. Among these new materials, especially polyurethane insulated sandwich panels have offered very economical solutions in terms of hygiene in cold rooms and storage areas thanks to their reliable temperature control and frequent washability. Polyurethane systems in sandwich panels used in various structures are far ahead of other materials with their high load carrying capacity, long service life, moisture and fire resistance as well as providing heat, water and sound insulation. 

It can be produced as 2,3,4 or 5 components between painted galvanized sheet, aluminum, membrane or stainless steel in machines (high pressure) specially manufactured for this system. 

The presence of polyurethane in sandwich panels, which can be used in factories, shopping centers, stadiums, as well as in the manufacture of cold storages or prefabricated structures, is very important.

PLUSOL R-10x-xx & PLUSNATE R-100-01 can be used in two-component systems and we continue our innovations with our specially formulated products for these systems. 

In addition, if the features of the machines used are suitable, they are formulated in 3-4 and 5-component systems. Here, the density can be adjusted on the production line by using n-pentane gas from outside.

General characteristics of this system and raw materials:

a.    Fast production
b. Thermal insulation 
c. Low consumption (up to 25% compared to the amount of polyurethane used per m2 in batch production)
d. High mechanical resistance
e.    High compressive strength
f. High water absorption resistance
g.    High temperature resistance
h.    Sound insulation
i.    High chemical resistance
j.    Fire performance

"Polyurethane systems are sensitive to moisture and high temperatures. It is recommended to store unopened original packages on pallets in a dry, moisture-free environment at room temperature. 

Products should not be exposed to direct sunlight. "
