What is PS plastic? Application of Polystyrene resin in interior decoration materials industry

Plastic PS is a plastic that is easy to process and shape and is widely used in the interior decoration materials industry. Kosmos will provide information about this plastic soon!

What is PS plastic?

Plastic PS is a thermoplastic polymer whose scientific name is Polystyrene. The thermoplastic PS polymer is transparent white in color and is commonly found in solid or porous form. We can easily color this plastic to meet the aesthetic.

Features of Polystyrene resin

The main characteristics of PS plastic are transparent, hard and brittle. We can increase the impact resistance of this plastic by combining with other materials. They can turn into a liquid at 100 degrees Celsius and turn back to a solid when cooled. This feature makes PS plastic easy to shape by extrusion (foaming), vacuum forming (film forming) and molding.

Polystyrene Non-toxic, odorless and is the plastic used mainly in the food packaging industry. Polystyrene is relatively chemically inert, impermeable, and resistant to degradation by many acids and bases. In particular, the PS resin formed after molding has a high degree of detail.

Polystyrene plastic classification and applications of each type

Have 5 The main types of Polystyrene are: EPS (Expanded polystyrene), XPS (Extruded polystyrene foam), OPS (Oriented polystyrene), HIPS (High Impact Polystyrene) and  GPS (General Purpose Polystyrene).

Expanded polystyrene – EPS

EPS is ps plastic foam. EPS foam is manufactured by expanding small polystyrene particles in a mold, through heat and steam. The uneven expansion process causes the EPS foam sheet to contain small gaps. The spaces above will be the place to absorb air and moisture. Therefore, EPS foam is the ideal solution for humid environments. Common applications of EPS are:

  • Food container.
  • Fragile storage box.
  • Insulation panels.
  • Make motorcycle helmets.

Extruded polystyrene foam – XPS

XPS also foam polystyrene. However, XPS foam is manufactured by extruding Polystyrene with other additives and allowing it to cool. XPS foam has no gaps, so it is 100% water and air resistant. It can be said that XPS foam is the best solution for wet environments. The common applications of XPS foam are:

  • Blue Board is manufactured by Dow Inc.
  • Depron thin sheet insulation (depron foam).
  • Building materials for architectural models.

Oriented polystyrene – OPS

OPS is a polystyrene resin stretched to form a film. When stretched, the OPS film is reduced in opacity and has improved stiffness. OPS is an environmentally friendly packaging material. OPS wrappers are relatively cost effective and are used for packaging deli items. People often use OPS wrapping film to see the contents inside the package. However, this wrapper is prone to cracking or tearing.

High Impact Polystyrene – HIPS

HIPS is a PS resin with high impact strength and good dimensional stability. HIPS resin has a natural white color with a matte finish. We can enhance the aesthetics of this plastic by painting and gluing. A typical application of HIPS plastic is in yogurt containers. Typically, HIPS resins are used for utensils that require resistance to cracking due to high environmental pressures.

General Purpose Polystyrene – GPPS

GPS is a PS plastic with poor brittleness and impact resistance. GPPS also doesn't have as good dimensional stability as HIPS. However, GPPS plastic has the same clarity as glass, so it is commonly used for food packaging. This plastic can be easily molded into different shapes, so it is also used to make toys for children.

Application of PS plastic in interior decoration materials industry

As we all know, PS plastic is a type of plastic that is easy to shape and color, so the process of processing ps plastic is extremely easy. PS plastic interior decoration materials have various shapes. Small details on materials are reproduced extremely meticulously and beautifully. That is not to mention the ability to standard color of this plastic.

Interior decoration materials made of polystyrene can include: ps . plastic sheet (Korean fluted panel) and PS plastic molding (Korean molding). You can go to the Fanpage of decorative materials supplier Kosmos Vietnam to see samples at HERE!

Some characteristics of PS plastic decorative materials can be mentioned as:

  • Light weight, easy to transport and install.
  • Standard colors, nice shape.
  • Water resistant, easy to clean.
  • Effective electrical and thermal insulation.
  • The ps wave bar has noise resistance.
  • Premium PS material with added air filtration.

Summary

Plastic PS Plastic is widely used in the field of interior decoration materials. Plastic Polystyrene Popular not only because of its beautiful shape but also because of its waterproof, heat-insulating, insulating properties, etc. If you need to be a distributor of PS plastic panels, ps plastic molding, please contact the Kosmos hotline immediately.
