Chapter Two Common Sense of Extruded Board (15 Questions)

1. What is the extruded board?

A building insulation board with a continuous and uniform surface layer and a closed-cell honeycomb structure made of polystyrene resin and other additives.

2. What are the characteristics of polystyrene resin?

English name: Polystyrene

Abbreviation: PS

A thermoplastic non-crystalline resin with heat insulation, insulation, high rigidity, translucent, water, and chemical resistance.

3. What is the classification of polystyrene resin?

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).

4. What are the uses of GPPS?

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.

5. What are the names of extruded boards?

Full English name: Extruded Polystyrene Board

English abbreviation: XPS

6. What is the difference between the polystyrene board and the extruded board?

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.

7. What are the classifications of extruded boards?

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.

8. What is the use of extruded board?

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.

9. What is passive architecture?

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.

10. What factors are related to the cost of the extruded board?

The price of extruded board is directly related to the grade of raw material, density, and flame retardant grade.

11. Professional website for extruded board?

Feininger: https://www.feiningercn.com

12. What are the raw materials of foam plastics?

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.

13. What are the fillers of foam plastics?

Commonly used are glass, calcium carbonate, carbon black, barium sulfate, silicate, wood powder, and metal powder.

14. What are the additives for foam plastics?

Generally, there are foaming agents, crosslinking agents, coloring agents, nucleating agents, antistatic agents, stabilizers, dispersants, flame retardants, and so on.

15. What is the development history of the extruded board in China?

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.
