PS sheet

PS sheets of polystyrene or Himpack

Polystyrene sheet, or hypack, or PS sheet is a polymer made from styrene monomer (liquid hydrocarbon from petroleum derivatives). At normal temperatures, polystyrene is solid and flexible, but at higher temperatures it can melt into a paste. Polystyrene or hips is an aromatic monomer, so polystyrene is also an aromatic polymer.

If you have a molecular structure of polystyrene or hips. Look, you will see that this polymer is made up of only carbon and hydrogen atoms. Therefore, it is in the group of hydrocarbons. If you look at the bonds in its chemical structure, you see that the carbon atoms are connected by a covalent bond.

In the polystyrene or hips chain, to each alternating carbon atom, a group of phenyl (benzene ring) is attached. The hips polystyrene sheet is a long-chain hydrocarbon with a chemical formula of C8H8. What distinguishes these hips polystyrene sheets from other sheets is the formation in mold and excellent formability compared to other polymer sheets.

Hips polystyrene was first produced in 1940 by the German company I.G.Farben Industries and used as insulation in the electrical industry. Today, Hips polystyrene is one of the most popular plastics in the food industry, such as dairy companies. Chocolate is used in disposable tableware and many consumer packaging.

This product was produced for the first time in Iran in 1334 by Ionolite Company; Hence it is known in Iran as Ionolite
May be. Polystyrene is a styrene-derived polymer that is produced and used in conventional grades (PS), resistant (HIPS), expandable (EPS) and extruded (XPS).

HIPS polystyrene grade with the full name of high-impact polystyrene (HIPS) is impact resistant and resistant to cold and heat, and therefore is used in the manufacture of disposable tableware and the body of home appliances and packaging.

Ordinary polystyrene or crystal is somewhat brittle, although it is possible to obtain a softer product by adding some materials such as polybutadiene. However, the addition of polybutadiene during the polymerization process results in the chemical bonding of polystyrene to the production of a copolymer. Thus polybutadiene is included in the final composition and leads to the production of resistant polystyrene.

Coloring of PS sheets

HIPS plastics (highpack sheets) with various colors. Such as colors: white, black, yellow, red, blue, brown, etc., which are produced at your request, dear manufacturer.

Applications of polystyrene sheet

If you are looking for a plastic sheet with special colors, dimensions and thicknesses that has the impact resistance of forming in the mold, the HIPS sheets of Waqif Production Group will be your first choice. Due to the fact that polystyrene is highly heat able and malleable, various shapes and objects can be produced from these sheets.

Suitable for plastic doors, paper cups and seedling trays in various dimensions and cavities and food packaging such as honey, butter, cheese and single jams. Hypex sheets do not break or puncture easily. This plastic (highpack sheet) is known as a heat and cold resistant plastic, unique and special.

Resistant polystyrenes (HIPS) are used in the construction of houses (toys) and in the manufacture of disposable tableware and the body of home appliances and electrical appliances, and even machine building and refrigerators and many more به due to their high impact resistance. They are also widely used in the manufacture of sports equipment and toys, and almost any plastic object in your mind can be made of HIPS polystyrene. Today, one of the most interesting decisions made by a group of sandwich panel manufacturers is to make the hard and protective layer of sandwich panels from hard polystyrene (HIPS) and the inner layer of EPS or XPS polystyrene.

HIPS is used to produce disposable tableware, electronic packaging, watch case, TV, radio, refrigerator body, sports equipment, refrigeration insulation, home appliances, toy making, packaging, etc. . Inside refrigerators, the first cold-resistant layer is often used HIPS sheets.

In addition to cold resistance, one of the special features of HIPS sheets is the antibacterial property on the surface. The stiff and impermeable nature of air and bacteria makes it more suitable for food packaging than other materials. It is also more suitable for packing fatty foods such as butter, cream, chocolate. This material can be used in food packaging applications with low heat, but is not recommended for packaging with temperatures above 85 ° C.

It can be pointed out that from resistant polystyrene, various shapes after heating and pulping the sheet in various molds. Can be made and produced. This is because HIPS plastic (Heimpec sheet) has the ability to heat. The reason for this is high-strength (resistant polystyrene) sheet, high strength, high color ability, high printability, adhesion and also unique molding.
