Balsa
Balsa wood (also known as light wood) is a natural, ultra-lightweight hardwood, renowned for its specific strength and excellent thermal and shock insulation properties. By using balsa wood as the core material in composite sandwich structures, the overall weight can be significantly reduced while maintaining structural rigidity and strength, and the product's thermal insulation, sound insulation, and impact resistance can be improved, providing a key material solution for modern industrial design.

Structural Foam Materials
Structural foam materials are a type of lightweight and high-strength composite core material. Through the "sandwich structure" design, they can significantly reduce weight while improving the stiffness and strength of components, and bring excellent properties such as heat insulation, sound insulation, and fatigue resistance.
Fiber-Reinforced Foam Materials
Fiber-reinforced foam materials are a new type of lightweight, high-strength material that combines the advantages of structural foam, functional resin, and reinforcing fibers. They feature low density, high strength, good lifespan, high pull-out resistance of rail spikes, and excellent fatigue resistance. Among these, continuous fiber-reinforced polyurethane foam materials are a particularly important category, widely used in lightweight structures, synthetic sleepers, and wood-look structures.
Solid Buoyancy Materials
Solid buoyancy materials, as a type of functional composite material, are widely used in marine equipment due to their advantages such as high net buoyancy, excellent pressure resistance, low water absorption, and strong resistance to seawater corrosion, providing reliable performance assurance. Solid buoyancy materials are mainly composed of resin and uniformly dispersed tiny hollow glass or ceramic microspheres, and are highly customizable.
