Expandable Polystyrene Foam Can be Used As Fire Resistant Material

Foam is a national economic development after relaying steel, timber, cement and the formation of a class of building materials industry. China's plastic building materials began in the early 1980s, after years of scientific research, technology transfer and product development, has made great achievements.
Compared with many traditional building materials, foam in addition to excellent processing performance, light weight, excellent decorative, but also has good thermal insulation properties, etc., so the foam has been rapid development in recent years. Expandable Polystyrene is an important category, due to the light weight, thermal insulation is good, there is a certain strength, etc., Expandable Polystyrene is widely used in the construction. By extrusion molding, compression molding, cast molding and other production processes, Expandable Polystyrene composite materials can be made into a variety of other pipe fittings, aluminum composite panel, color steel and other building materials, widely used in the construction duct insulation, ground insulation, wall insulation, roof insulation, and other surfaces. Due to its versatility, the 2002 global Expandable Polystyrene production has reached 13.93 million tons, consumption amounted to 14.13 million tons. Expandable Polystyrene synthetic resin by the polymerization method can be divided into the polyaddition resins and polycondensation resins, can be classified according to the behavior of the heated thermoplastic resin and a thermosetting resin types, from the open and closed cell structure can be divided into two kinds, may be different from the rigid divided into hard and soft foams in two, mainly used in construction is a rigid closed cell foam.
Although Expandable Polystyrene Foam has a lot of good performance, but poor combustion performance is a very important flaw, largely limiting the Expandable Polystyrene used in a building.
Expandable Polystyrene materials water absorption, high mechanical strength, thermal insulation used on the building roof, walls, plumbing, floors have better performance than traditional materials, due to its good insulation, moisture, corrosion resistance, but also a great choice for interior decorating. On the structure of Expandable Polystyrene building insulation materials together with other applications.
However, on the other hand EPS combustible materials, have to consider the use of its fire-retardant properties. Formed by the polymerization of styrene monomer Expandable Polystyrene produces yellow-orange flame combustion, and a lot of smoke coming out of carbon beam.,issued a special styrene odor, very toxic. Therefore, the application of Expandable Polystyrene in the construction, the need for effective fire-retardant treatment.
