What is High Impact Polystyrene material? This material has a higher resistance than General Purpose polystyrene, which is made of a mixture of two materials, polystyrene and polybutadiene. To make High Impact Polystyrene (HIPS), the desired materials are placed on hot rollers and combined with internal mixers, which is also called extrusion.
Currently, the production of High Impact Polystyrene is formed by the dissolution of molecules in polybutadiene rubber in styrene monomer. Join us to learn about shockproof polystyrene ingredients.
HIPS Material
What are the properties of High Impact Polystyrene material?
High Impact Polystyrene, or HIPS for short, is a type of bonded polymer. As we mentioned at the beginning, this product is a combination of two materials, polybutadiene and polystyrene, which results in very durable plastic material.
Features of polybutadiene include high shock absorption and flexibility. Polystyrenes have advantages such as high strength and durability. These features make the produced polymer product have significant elasticity. However, GPPS or standard polystyrenes will not have this feature.
High Impact Polystyrene material makes this PS extremely strong, also greatly reduces its fragility, and at the same time can withstand a lot of impacts and withstand pressure and heavy shocks. This is the reason why this polystyrene is called resistant and shockproof. This type of polystyrene is known as one of the oldest examples of thermoplastic in the world. These materials are made using monometric polymerizations.
Uses of HIPS
What are the uses of High Impact Polystyrene materials?
The materials of this polystyrene are a kind of impact-resistant plastic that is used in the manufacture of home appliances and all kinds of utensils. This type of plastic is very light and has high flexibility and low price. Due to the unique advantages of this material, it is used in various industries. This material has a variety of colors and is easily broken and perforated.
High Impact Polystyrene materials can heat; For this reason, it is possible to produce different shapes with it. In the production process of this type of polystyrene, 10% of butadiene is added to it, which increases the strength and high impact resistance.
The reason for paying attention to High Impact Polystyrene is the possibility of high paintability, remarkable strength, excellent moldability, and very high adhesion.
This material is one of the best basic resins used to produce electrical agents, building compounds, and general merchandise. Resistant polystyrene is known as a type of non-crystalline resin, due to changes in the degree of crystallization about the cellular structure have caused a great change in the properties of resistant polystyrene.
Introduction of High Impact Polystyrene materials
As mentioned, polybutadiene is one of the main materials of High Impact Polystyrene, which is in the form of a light yellow solid rubber. This material is odorless and has a high melting point. This substance is stable under natural conditions but should not be exposed to oxidants.
What are the uses of High Impact Polystyrene?
This type of polystyrene is used as the first cold-resistant layer in refrigerators and freezers. Another application is in 3D printers.
This model is made of polystyrene normally with the addition of 5-10% butadiene or rubber copolymer. This makes this type of polystyrene more resistant and harder than GPPS. So HIPS is used as a suitable product with high hardness and is ideal for use in all types of packaging.
This type of polystyrene has the possibility of reprocessing temperature, dimensions, adhesion, printability and is considered as one of the 5 main resins in the construction and manufacturing of electronic devices.
Impact-resistant polystyrene material has a high resistance and has antibacterial properties on its surface.
Another feature of this product is its low cost, which has received a lot of attention. Use in various packages and sandwich panels is another use of High Impact Polystyrene.
