Polyurethane Catalysts in Sandwich Panels: Enhancing Insulation and Production Efficiency

Sandwich panels have become an essential component in modern construction due to their outstanding thermal insulation, structural strength, and installation efficiency. Among various types of sandwich panels, those with polyurethane (PIR) core materials are increasingly preferred across industries for their superior performance. As a manufacturer of high-performance polyurethane catalysts, we are proud to support the production of these panels through reliable and efficient solutions like MXC-T, MXC-C15, and MXC-37.

What Are Sandwich Panels?

Sandwich panels are composite building materials made up of three layers: a low-density core material, such as expanded polystyrene (EPS), mineral wool, or polyurethane (PIR), and two outer skin layers, typically made of metal sheets. This layered construction offers high strength-to-weight ratios, making the panels ideal for a variety of structural and insulation purposes.

Why Polyurethane (PIR) Sandwich Panels?

Among the different types of insulation core materials, polyisocyanurate (PIR)-based sandwich panels are widely recognized for their low thermal conductivity, meaning they provide better insulation with thinner panels. The result is greater energy efficiency, which is vital for:

Polyurethane sandwich panels offer additional benefits, including:

rigid polyurethanes

The Role of Polyurethane Catalysts in Sandwich Panel Production

Polyurethane catalysts play a critical role in the manufacturing of sandwich panels. These catalysts accelerate the reaction between polyols and isocyanates, enabling the controlled foaming and curing process needed to form the PIR core.
At Mingxu New Materials, we offer a range of specialized polyurethane catalysts tailored for sandwich panel applications, including:

Together, these catalysts ensure balanced reaction control, uniform foam rise, and consistent insulation quality, meeting the high standards required in modern construction materials.
