General purpose polystyrene
Polystyrene is produced in 3 grades of impact resistant HIPS, ordinary GPPS polystyrene and EPS expanded polystyrene. Ordinary GPPS polystyrene is a thermoplastic polymer. Today, polystyrene is one of the most popular plastics needed and used in most industries. Among the things that have led to the development of this polymer is its transparency, ductility and low price. Which has created a special place among different types of polymers. In the following, we will examine the typical grade of this polymer.
A variety of ordinary polystyrene grade names
scientific name: (General Purpose Polystyrene )
Persian brand: (GPS)
English brand: (GPPS)
Other names: Crystal polystyrene, polystyrene polymer, ethyl benzene homopolymer
Types of materials used to make this polystyrene
V Global polystyrene production capacity in previous years, with an average annual growth of 75.5% from 8.7 million tons in 1990 to 18 million tons in 2003. Which increased more than twice during this period. This plastic, unlike other plastics, has no crystalline properties and is transparent. Ordinary grade polystyrene has good resistance to water absorption and excellent thermal and electrical insulation. With a global consumption of 14.7 million tons, this polymer accounts for about 9% of the consumption of basic polymers.
Disposable utensils, electrical appliances, watch and TV and radio bodies, sports appliances, toys, refrigeration insulation, refrigerators and home appliances.
GPPS is hard and transparent with excellent ductility. It should also be noted that this polymer is brittle in the unmodified state; In the industry and market, this polymer is also called crystal. Its most common use is in the production of disposable tableware, due to properties such as: Transparency, resistance to moisture absorption, odorlessness, electrical insulation, reasonable price and good molding properties have been widely welcomed. For this reason, GPPS is used in the manufacture of tools such as health, sports, automotive, home appliances, computers, razors, electrical, fans and..
