SOHO® High Compressive Strength XPS is produced by CNC intelligent equipment imported from Germany. The homogeneous foaming rate can reach 99.99%. The product homogeneity is at the top of the industry, and no additives are added to maintain performance indicators in the short term. Under alternating strong load and temperature conditions, the creep resistance, compressive strength, hydrophobicity and thermal insulation performance of the material are basically not reduced for 50 years.

SOHO high compressive strength XPS, known as Plastpak® board, exhibits excellent thermal insulation properties. At a test temperature of 25°C, its thermal conductivity is 0.028 W/m·K; at a test temperature of -20°C, its thermal conductivity is only 0.023 W/m·K. Its thermal conductivity at low temperatures is lower than that of polyurethane, which is 0.025 W/m·K at -20°C.
SOHO high compressive strength XPS has a volume water absorption rate of less than 1% and a water vapor permeability of 3 ng/Pa·s·㎡. Water absorption is a crucial indicator affecting insulation performance. When the material absorbs water, it displaces the gas within the material, with water occupying the original space. Since the thermal conductivity of water is 1 W/m·K, the thermal conductivity of the insulation material increases. Therefore, the higher the water absorption rate, the poorer the insulation effect. Due to its excellent water resistance, the insulation effect remains above 98% after 200 freeze-thaw cycles.
SOHO high compressive strength XPS is a material that maintains more than 80% of its insulation performance even after 50 years of use. It meets fire performance standards of B1 and B2 levels. Its convenient construction performance, factory-produced forming, and large-area assembly on-site make it safe, convenient, and quick.
SOHO high compressive strength XPS is a lightweight, high-strength board. With a density not exceeding 40 kg/m³, its compressive strength can be selected within the range of 200 kPa for wall applications to 1200 kPa for heavy-load high-speed rail applications.
SOHO high compressive strength XPS has stable chemical properties and uses environmentally friendly raw materials from companies like BASF. It uses carbon dioxide (CO2) foaming, does not contain freon gases, halogens, or bromides, and does not emit harmful substances during use. It will not decompose or mildew and has good corrosion resistance. The entire production and application process is green and environmentally friendly.
