Chapter Two Common Sense of Extruded Board (15 Questions)
A building insulation board with a continuous and uniform surface layer and a closed-cell honeycomb structure made of polystyrene resin and other additives.
English name: Polystyrene
A thermoplastic non-crystalline resin with heat insulation, insulation, high rigidity, translucent, water, and chemical resistance.
It is mainly divided into general-purpose polystyrene (GPPS, commonly known as transparent benzene, extruded board raw material), impact-resistant polystyrene (HIPS, commonly known as modified benzene) and foamed polystyrene (EPS beads).
Daily necessities such as disposable tableware, toys, packaging boxes, bottles, plates, etc.;
Insulation materials, freezing and heat insulation, heat preservation, sound insulation, earthquake resistance, and other fields;
Telecommunication and electronic fields such as instrument housings, lampshades, and chemical instruments;
Optical fields such as light pipes, optical fibers, and optical lenses.
Full English name: Extruded Polystyrene Board
English abbreviation: XPS
The raw materials of the polystyrene board (EPS) and extruded board (XPS) are both polystyrene resin. But the production process is different, EPS is water vapor foaming, XPS is foaming continuous extrusion. Most of the material properties are the same and can be used as insulation materials.
According to whether the surface is treated or not, it is divided into the ordinary extruded board and surface-treated extruded board. According to the flame retardant grade, it can be divided into B1, B2, and B3. It can also be classified according to color, density, and purpose.
Due to its unique material properties, extruded panels are often used in insulation fields such as building roof and exterior wall insulation, floor heating insulation, cold storage, cold chain transportation of medicines and foods, and also used in high-speed and airport foundation laying, construction filling and other fields.
Passive energy-saving houses (German: Passivhaus) can also be translated as passive houses, which are energy-saving buildings built based on passive design. Passive houses can adjust the room to a suitable temperature with very little energy consumption, which is very environmentally friendly.
The price of extruded board is directly related to the grade of raw material, density, and flame retardant grade.
Commonly used are polystyrene (PS), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), acrylonitrile-butadiene-styrene copolymer (ABS), polyurethane (PU), phenolic aldehyde resin, urea-formaldehyde resin, etc.
Commonly used are glass, calcium carbonate, carbon black, barium sulfate, silicate, wood powder, and metal powder.
Generally, there are foaming agents, crosslinking agents, coloring agents, nucleating agents, antistatic agents, stabilizers, dispersants, flame retardants, and so on.
In the 1930s, Mr. Owens Corning produced XPS foam in the inner pot and entered mainland China in the 1990s. In 1997, the first XPS production line was put into operation in Nanjing.
Feininger is the first professional manufacturer of XPS Extrusion Line and XPS Foam Board in China. At the same time we are the unique enterprise specializing in XPS Foam as well as developing, manufacturing and selling of XPS extrusion line. We also manufacturing ETPU extrusion line, PET production line, EPS production line, recycling and pelletizing machine, etc. Contact us for more details.
