Sandwich panels have become a cornerstone of modern construction, offering exceptional thermal insulation, structural strength and energy efficiency. At the heart of these panels is polyurethane foam, a material that owes its performance to the right catalyst. At Mingxu Chemical, we specialize in advanced polyurethane catalysts to optimize the production of sandwich panels, ensuring superior quality and performance.
In this article, we explore the key role of polyurethane catalysts in sandwich panel manufacturing and how our solutions can help you achieve outstanding results.
What is a sandwich panel?
Sandwich panels are a composite material consisting of three layers:
1. Two outer layers (facers): Typically made of metal, plastic or wood, providing structural strength and protection.
2. Core layer: Typically made of polyurethane foam, which has excellent thermal insulation and lightweight properties.
These panels are widely used in construction, cold storage, industrial construction and transportation due to their durability, energy efficiency and easy installation.
The role of polyurethane catalysts in sandwich panel production
Polyurethane foam is a key ingredient in sandwich panels, and its performance depends largely on the catalyst used in the production process. Catalysts play a vital role in:
1. Controlling the reaction rate: Catalysts regulate the reaction between polyols and isocyanates, ensuring optimal foam expansion and curing.
2. Reinforcing the foam structure: They help form a uniform cell structure, which improves the thermal insulation and mechanical properties of the foam.
3. Improving adhesion: Catalysts ensure a strong bond between the foam core and the outer layer, enhancing the durability of the panel.
4. Optimizing processing time: By accelerating or delaying specific reactions, catalysts allow manufacturers to fine-tune production efficiency.

Our catalysts for sandwich panels
Our catalysts are tailored to meet the unique needs of sandwich panel manufacturing:
1. Building panels
For wall and roof panels used in residential and commercial buildings, our catalysts ensure excellent thermal insulation, fire resistance and structural integrity.
2. Refrigerated panels
In refrigerated warehouses and cold rooms, our catalysts help produce foam cores with low thermal conductivity, ensuring energy efficiency and temperature control.
3. Industrial panels
For factory buildings and warehouses, our catalysts provide strong, lightweight panels that can withstand harsh environmental conditions.
4. Transport panels
In car body and container panels, our catalysts ensure lightweight, durable and thermally efficient solutions.
Our sandwich panel portfolio
We offer a range of catalysts designed to meet different production needs:
- The product name of MXC-37 is 2-(2-(dimethylamino)ethoxy)ethanol, abbreviated as DMAEE, with a CAS number of 1704-62-7. It is a non-emitting, low-odor amine catalyst used in the production of polyurethane foams. Due to its high foaming activity, it is particularly suitable for formulations with high water content, mainly for low-density, water-blown cellular spray polyurethane foam (SPF). Incorporating DMAEE into the polymer minimizes the amine odor common in foams. It can be used alone as a primary catalyst or as a co-catalyst to reduce the use of BDMAEE foam catalysts. Used in ester-based stabilizer soft foams, microcellular foams, elastomers, RIM and RRIM, and rigid foam packaging applications.
- MXC-C15 stands for 3,3′-Iminobis(N,n-dimethylpropylamine), CAS NO. 6711-48-4, is a non-emitting, low-odor reactive amine catalyst that is slightly selective for urea (isocyanate-water) reactions. It improves surface cure in flexible molding systems. It can be used in rigid polyurethane systems that require a smooth reaction curve.
