Rigid Panel Grade Polyurethane

Rigid Polyurethane Panel Grade Materials
Rigid polyurethane foams are one of the most well-known and highly efficient multi-purpose insulations in the industry. Unlike flexible foams, which are primarily a comfort factor, rigid polyurethane foams are known for their physical strength and insulating properties. One of the fundamental differences between polyurethane foam and other insulation materials (such as PVC foam, PS foam or PE foam) is the fact that the polyurethane raw materials, including polyols and isocyanates, are reactive liquids and do not require external heat for foaming.

Rigid polyurethane foams in panel grade are mainly used to manufacture steel sandwich panels with high strength and stability in thicknesses of 4 to 15 centimeters. Polyurethane sandwich panels are also used in various applications, such as the construction of fixed and mobile cold stores (refrigerated trucks, refrigerated railway wagons, etc.), as well as in the construction of industrial sheds in the wall and ceiling sections, depending on the thickness, insulation quality, and the type of steel sheet forming. It is worth noting that the raw materials for the production of panel grade polyurethane foam are divided into two types of non-continuous panel grade polyel and continuous panel grade polyel, depending on whether the customer's production line is designed as discontinuous or continuous.

Polyurethane Razin Company offers various types of polyel in different grades for use in various applications in the hard panel grade section as follows:
