Extruded sandwich panels based on polystyrene resin as the main raw material, by a special process for new insulation sheet extrusion foam molding, also known as XPS board. The board closed-cell honeycomb structure, compared with traditional materials with excellent insulation properties, and high compression, non-absorbent, lightweight, anti-aging characteristics, is ideal for high-index engineering energy-saving materials. More applicable to the construction and highway projects, insulation, heat insulation, sound insulation, moisture-proof handle.

  
Features:
A stable, environmentally friendly 2. Noise, fire-retardant. Most economical cost. Excellent thermal insulation properties. Extraordinary compressive characteristics of good moisture
Excellent insulation properties
Road closed foaming structure and advanced technology has created the excellent quality of extruded sandwich panels, the best state to reach its thermal insulation properties, thermal conductivity: 0.28w/mk, and polystyrene foam board compared to insulation insulation excellent performance nearly doubled nearly three times better than the hydrophobic perlite board, so it is a highly efficient energy-saving materials can adapt to and capable of a high standard of modern engineering energy conservation requirements

Extruded sandwich panel is a lightweight high-strength plate, the compressive strength ≥ from 150, has a strong bearing capacity and impact force to make up for the shortcomings of the traditional sandwich panel material is soft and fragile, it combines building materials characteristics.
Good water resistance
Extruded sandwich panel less than 1% water absorption, water vapor permeability coefficient is less than 3 ng (mspa), has good moisture-proof, waterproof and impermeable, can effectively prevent the water molecules to other objects through the insulation layer dip the useful life of the eclipse, in order to the Director of the engineering system. Extruded sandwich panel material chemical properties are stable and not decompose and mildew, excluding volatile and harmful substances, the certification authority for green products.
Sound insulation, fire-retardant
The honeycomb cell structure of extruded sandwich panel material with a noise canceling noise function, so it can also be used as the insulation materials. The flame retardancy of the board can fully meet the requirements of fire engineering.
