Polystyrene (PS)

  • Genereal purpose polystene (GPPS)
  • High impact polystyrene (HIPS)

General Purpose Polystyrene, commonly known as GPPS, is a transparent, rigid thermoplastic polymer that is commonly used in a variety of applications. 

It is a low cost material with good dimensional stability, clarity, and processability. GPPS is typically produced through suspension polymerization of styrene monomer.

The main applications of GPPS include:

  1. Packaging: GPPS is used in the production of various packaging materials such as food containers, disposable cutlery, and blister packaging. Its transparency and low cost make it an ideal material for these applications.
  2. Consumer goods: GPPS is used in the production of various consumer goods, such as electronic housings, toys, and housewares. Its rigidity and ease of processing make it an ideal material for these applications.
  3. Stationery and office products: GPPS is used in the production of various stationery and office products, such as pens, rulers, and staplers. Its clarity and ability to be molded into intricate shapes make it an ideal material for these applications.
  4. Electrical and electronic components: GPPS is used in the production of various electrical and electronic components, such as light fixtures, switch plates, and covers. Its rigidity and ability to be molded into complex shapes make it an ideal material for these applications.
  5. Automotive parts: GPPS is used in the production of various automotive parts, such as dashboards, instrument panels, and interior trim. Its ability to be molded into intricate shapes and its rigidity make it an ideal material for these applications.

In addition to its general-purpose grade, GPPS is also available in various grades with enhanced properties for specific applications, such as:

  1. High Impact Grade: This grade of GPPS has improved toughness and impact resistance and is commonly used in applications where impact resistance is important, such as food packaging and toys.
  2. Extrusion Grade: This grade of GPPS has improved melt strength and is used in applications such as thermoforming, sheet extrusion, and blow molding.
  3. Medical Grade: This grade of GPPS is used in medical applications such as diagnostic devices and drug delivery systems due to its purity and biocompatibility.

In summary, GPPS is a versatile and low-cost material that is widely used in various applications such as packaging, consumer goods, stationery, and automotive parts. Its ease of processing, dimensional stability, and clarity make it an ideal material for these applications. Different grades of GPPS are available with enhanced properties for specific applications.
