XPS heat preservation board is a kind of extruded polystyrene heat insulation board. It is made of polystyrene resin as raw material, with other raw materials and accessories and poly-inclusions, through a special process of heating, mixing and injecting catalyst, and then continuous extrusion and extrusion molding of rigid foam plastic board. Its scientific name is extruded polystyrene for insulation. Foam plastic (XPS), XPS has a perfect closed-cell honeycomb structure, this structure makes XPS board has very low water absorption (almost no water absorption), moisture-proof, air-tight, light weight, corrosion resistance, low thermal conductivity, high compression resistance, aging resistance (normal use almost no aging decomposition), long service life, low thermal conductivity. Energy saving and environment-friendly insulation materials with excellent performance.

Its mechanical properties are incomparable with EPS, in addition, due to continuous extrusion due to the tight closed-cell structure. Its density, water absorption, thermal conductivity and steam permeability are lower than other types of plate, is currently recognized as the best insulation material.

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.
