RS-XPS: utilizes a fully automated, continuous extrusion foaming production line. By melt-blending polystyrene resin, flame retardants, and nucleating agents under high temperature and pressure, an eco-friendly blowing agent (CFC/HCFC-free) is injected. The mixture is then extruded through precision dies and rapidly cooled to its final shape.
Superior Compressive Strength: Possessing superior load-bearing strength, our boards can withstand long-term constant loads of up to 400 kPa.
Ultimate Moisture Resistance: With a closed-cell rate exceeding 99%, it has extremely low water absorption. Its thermal conductivity and mechanical properties remain constant even under long-term water immersion, effectively preventing mold growth and structural corrosion.
Long-term Thermal Efficiency: Since it does not suffer from gas leakage, its R-value remains stable throughout a service life of 30-50 years.
Superior Dimensional Stability: By utilizing a specialized Aging process to eliminate internal thermal stresses, we ensure that our boards remain free from warping, shrinkage, or expansion, even in regions with extreme temperature fluctuations—such as the Saudi Arabian desert, where diurnal cycles range from .
Sustainability & Chemical Resistance: Our products are 100% recyclable and possess high resistance to most acids and alkalis. They demonstrate robust, stable performance in infrastructure projects characterized by complex soil pH levels and corrosive environments.
 Global Adaptability: We offer customized solutions in various densities and thicknesses to suit diverse climates, ranging from the high-temperature deserts of Saudi Arabia to the high-humidity regions of India and Indonesia.
