Polyurethane
We have only two component rigid polyurethanes in our portfolio. You can find more info about them here:
Rigid polyurethane foams are suitable for a wide range of applications, including thermal insulation in buildings, flotation elements in boats, core materials in composite structures, adhesives, coatings, paints, and various molded technical components. In marine and shipbuilding industries, polyurethane foams often carry the necessary regulatory approvals to ensure safety and buoyancy.
Rigid polyurethane foams are dense, lightweight, and stiff foams used for mold filling, as core materials in composites, or for reducing weight in components. They cure through a chemical reaction, forming a structurally strong yet lightweight material.
Rigid foam is used when a structure needs to be easily shaped but also stiff and dimensionally stable. Once cured, the foam can be sawn, milled, or sanded, making it ideal for shaping prototypes, mold bases, or internal frames of sculptures.
Advantages of the material include its light weight, good compressive strength, and excellent machinability. It can be worked with standard woodworking tools. The foam can be cast into a mold, filling the space precisely and curing without the need for high temperatures. Sprayable variants are also available. Curing time depends on the product, but in most cases, the material is ready to use within minutes.
Rigid polyurethane foams are commonly used for:
- Cores in laminate structures for boats and vehicles
- Filling large molds
- Custom packaging solutions
- Lightweight structural components under mechanical stress
