Why XPS foam board so popular?
XPS extruded board has stable chemical properties, no volatilization of harmful substances, no decomposition or mildew, and good corrosion resistance. In the production process of XPS extruded board, environmentally friendly raw materials are used, no harmful gases are generated, and the environmental protection concept is also reflected in the production process. The solid waste generated can be recycled and used, which is a recyclable and environmentally friendly product.Extruded plastic board is a kind of heat and pressure resistant material, which has the effect of heat insulation and heat insulation. It is widely used in the field of external wall insulation, but the focus of customers is on the price of extruded plastic board, which affects the extruded plastic board. The factors of price are: time factor
The first and fourth quarters of each year are the off-season of engineering construction. Excess supply in the extruded board market will cause downward prices. The second and third quarters of each year will be the peak season for engineering construction. The supply of the extruded board market will be tight and prices will rise.
Bad performance of extruded board: energy consumption wastes heat. After the inferior extruded plastic board absorbs water, the water sucked in easily freezes at low temperature, which destroys the structure of the insulation material, thereby reducing the insulation performance of the board. Moisture content is an important factor that affects the thermal insulation effect of thermal insulation boards. Every 1% increase in moisture content is thermal insulation.
Boost the fire. Extruded board has the advantage of "flame retardant" because it contains additive flame retardant. However, in the recycling process, the flame retardant is easy to volatilize and not easy to remain. Some manufacturers even add no flame retardant at all to save costs. As a result, the original "flame retardant" has become an "easy to ignite"
