High impact polystyrene is a type of plastic that is easy to cast and make things out of it. People prefer to use them for their high impact strength, stiffness, and ease of processing. It is also known as HIPS or Polystyrene (PS); it is a clear plastic made from an amorphous thermoplastic material. They are produced by joining polystyrene and rubber particles by adding micron rubber particles.

High impact polystyrene is affordable which makes it economical available to all types of people. Many people have replaced products of moulded zinc with HIPS because it is a cheap replacement utilised in the composition of products.

Apart from immense strength, high impact polystyrene can be printed using digital, screen, flexo, and Litho inks and can be shaped and manufactured to make different objects. They come in different sizes and thicknesses, which are then moulded and formed to make various things that are useful in day-to-day activities.

Uses of High impact polystyrene:

  • Shelves and Fixtures
  • Digital displays that are placed near advertisements
  • Food packaging like meat trays, fruit and vegetable trays, egg cartons, etc.
  • Cassettes, CD shells, and their packaging
  • Jewel boxes and Trays
  • Disposable razors
  • Television parts and Computers
  • Prototypes and models
  • Parts of machinery
  • Household appliances and Cabinets
  • Refrigerator linings
  • Toilet seats and tanks

Properties of the HIP:

  1. Density is 1.07g/cm^3
  2. It has water absorption of 0.05%, which is pretty low, indicating that it doesn’t absorb water, making it water-resistant.
  3. The oxygen index is 18%. This measures the flammability of plastics as these two factors are directly proportional to each other. Thus, the higher the value of oxygen index, the higher the non-flammability; if it is low, it has low flammability.
  4. The flammability UL94 is HB which stands for horizontal burning and means that it is self-extinguishing.
  5. The maximum operating temperature of the HIP is 50 degrees Celsius.
  6. The melting temperature range is 200 degrees Celsius to 250 degrees Celsius, which allows it to be used in countries where the temperatures can be extremely high.

Advantages of high impact polystyrene:

  • It has good impact resistance which implies that it can withstand high energy without breaking or getting damaged.
  • The easy colouration feature adds benefits as one can find various hues and designs of polystyrene.
  • It is recyclable, affordable, and cheaper than other types of polymers.
  • It protects food from being contaminated with bacteria and germs.
  • It is known for its toughness, long-lasting and rigid nature, and availability.
  • It has high resistance against gamma radiation.

These benefits make the high impact polystyrene the perfect material for the uses it has. Because of its ease in moulding and affordability, it can be turned into different products, which is why its use has increased over time.

Also, it is a good barrier against germs and bacteria, so it keeps your food safe and fresh at all times. easy to carry everywhere with you due to their lightweight, without weighing you down or hindering your daily activities.

High impact polystyrene is a translucent material that is readily available at affordable prices to everyone. It has high resistance against dilute alkalis, aliphatic hydrocarbons, dilute acids, and other such chemicals. You can get them customised to fit your preferences and expectations, and they are easy to manufacture, which is why they can be purchased at low prices.

This material is used in everyday activities. It has a high melting point which makes it suitable to be used in hot countries and regions. Be sure to get in touch with professionals to avail you of more information about the topic of high impact polystyrene.
