XPS boards have perfect closed-cell honeycomb structure. This structure makes XPS boards lower than other types of plate insulation materials in water absorption, thermal conductivity and vapor permeability. Therefore, XPS boards have the characteristics of high pressure resistance, light weight, impermeability, corrosion resistance and non-degradation. XPS board is a very common thermal insulation material in European and American countries, especially suitable for the use of upside-down roofing insulation system, cold storage, wall insulation inside and outside, home decoration and so on. This product is suitable for roofing insulation layer regardless of heat insulation effect, construction simplicity, total cost, service life and other advantages than the traditional perlite, for new environmental protection and energy-saving materials, is currently the preferred building decoration industry materials.

The thermal conductivity of XPS / extruded sheet is less than or equal to 0.028w/mk, which is much lower than other thermal insulation materials, so it has the characteristics of high thermal resistance and low linear expansion rate. It is generally suitable for roof insulation system, freezer, wall insulation inside and outside the insulation, the effect is unparalleled.

Zibo Ruijing Building Materials Co., Ltd. is located in Zibo High-tech Development Zone. It is a private technology company integrating R&D, production and sales. The company has an annual output of 90,000 cubic meters of XPS insulation board production line. With a total investment of 5 million yuan, strong technical force and strict production technology, together with a sound scientific management model, the quality of the "Ruijing" series of products can always be recognized and praised by the market. Ruijing's product line mainly includes: xps extruded insulation board, EPS European components, fire equipment and so on.

The assembly line adopts internationally advanced production technology, and the extruded plastic insulation board has continuous and uniform standard layer and closed-cell honeycomb structure. Its unique high compressive strength, high heat, low thermal conductivity, low water absorption and low water vapor permeability coefficient can save energy, heat insulation, sound insulation, moisture, cold, waterproof and flame retardant. effect. This product is listed as the Ministry of Construction's 2002 Science and Technology (Building Energy Conservation Technology) Project Plan.
