Slabstock-Block Foam Polyurethane Systems
According to the manufacturers, slabstock polyurethane systems can have 2 to 8 components.
Slabstock foams with different free densities, like most foams, are prepared from basic ingredients (materials) such as polyols, isocyanates, catalysts, surfactants, blowing and foaming agents, flame retardants, antioxidants, and sometimes colorants.
In general, batch processes such as lamination and single-shot can be used with three main foam preparation approaches, such as semi-prepolymer (prepolymer) and prepolymer.
Polyurethane systems are sensitive to moisture and high temperatures. It is recommended that the unopened original packages be stored on the pallet, moisture-free, dry and at room temperature.
Products should not be exposed to direct sunlight.
