Familiarity with the Properties of GPPS is essential for the production of quality plastics. This material is one of the most widely used polymers in the world. In general, the use of GPPS in various industries has made this polystyrene grade very popular. This material has unique properties; For example, this material is very transparent and impact resistant.
It is used to make disposable appliances, home appliances, auto parts, and home insulation. The properties of GPPS are very diverse; In this PETROPROVIDERS article, join us to show you the Properties of GPPS.
This is a cheap grade of polystyrene. In general, polystyrenes have 4 different grades. These grades are GPPS polystyrene grade, EPS polystyrene grade, HIPS polystyrene grade, and XPS polystyrene grade. This material has various applications in different industries.
Making GPPS polystyrene is very simple. This material is made of styrene monomers. Styrene monomer contains 8 carbon atoms and 8 hydrogen atoms. This material has the structural composition of C8H8 n; That is, if a polymer contains 500 styrene monomers, it has 4,000 carbon atoms and 4,000 hydrogen atoms.
This polystyrene has an amorphous structure and is shiny. This material is transparent and has very strong bonds. In general, the Properties of GPPS are very diverse; This material has good impact resistance but is vulnerable to the sun.
It has various properties that produce various and durable plastics. In the following, we see the different properties of GPPS.
This material has little resistance to pressure; In contrast, the HIPS grade is highly impacted resistant. GPPS grade is used to produce disposable tableware and clear plastics. This material is damaged if exposed to the sun and its mechanical properties change.
This material is strong against tension and has a strength of 30 to 60 units. It is fracture-resistant and has about 30 to 40 units of resistance. This material has a flexural modulus of 3200 units and is resistant to pressure and bending. This material is vulnerable to light but has a strain strength of 1400 units against strain.
This material is very bright but does not have much resistance to pressure! It has strong intermolecular forces and is made up of monomeric chains. This material has different physical properties. As the temperature rises, the bonds between the atoms of the substance weaken and the monomers slide together. It is an elastic material and is used to produce plastic materials.
The physical properties of GPPS are:
It is resistant to chemicals, but if it comes in contact with strong acids, it reacts easily and changes. This substance catches fire and its smoke color is orange. After burning, it contains carbon particles in its smoke and, like all aromatic hydrocarbons, has toxic fumes.
It oxidizes to produce carbon dioxide and water vapor. It should be noted that this substance is also reactive against strong alkalis.
This polymer has unique electrical properties. It should be noted that this material has an electric field. Here are some electrical properties of GPPS:
GPPS polystyrene has unique thermal properties. This material has good resistance if it is in contact with direct heat. This material has good thermal conductivity and thermal expansion properties. It should be noted that this material is used to produce soft plastics or glass. This material melts without changing the temperature!
If the material melts without changing the temperature, it flows and is ready for molding. In addition, other thermal properties of GPPS include:
In this article, we looked at the Properties of GPPS and examined the applications of this polystyrene. This material is one of the most widely used polystyrenes in the world. In general, the use of GPPS in various industries has made this polystyrene grade very popular. This material has unique properties; For example, this material is very transparent and heat resistant. This polystyrene is used to produce disposable appliances, home appliances, car parts, and home insulation.
It has interesting electrical properties; For example, a flame temperature of 402 ° C, a thermal decomposition temperature of 300 ° C, and a user temperature of 20 to 60 ° C were recorded for GPPS.
This material has interesting physical properties. For example, water uptake of about 0.03%, shrinkage of about 0.5%, the refractive index of about 1.58%, and dispersion of about 90% were recorded for General Purpose polystyrene.
