Full acquaintance with Polystyrene mold + PS properties
Polystyrene mold is determined according to the application of polystyrene. This material, which is one of the most popular and widely used thermoplastics in the world, can be produced in various forms.
The most important applications of PS are for food packaging, building construction, home appliances, and CDs. Polystyrene mold must be cleverly made so that the texture of the polystyrene is uniform.
If we heat polystyrene, it becomes soft and can be easily produced in various molds. In the continuation of this PetroProviders article, join us to introduce you to Polystyrene mold.
Features of polystyrene in various forms
Features of polystyrene
One of the most important features of different polystyrene molds is their uniform structure. This polymer is very flexible and can be easily converted to any shape. An interesting feature of polystyrene materials is that these polymers become more durable when combined with rubbers. In general, polystyrene molds are programmed in different plans and the construction of these molds requires different tests.
Polystyrenes are resistant to UV rays and are also used for painting. However, it should be noted that this material is not highly recommended for outdoor use. Unlike outdoor use, polystyrene is very suitable for indoor use.
PSs are resistant to weak acids and alkalis. But they do not have much resistance to chemical reactants. In general, GPPS polystyrene is resistant to temperatures of 68 to 93 ° C. The tensile strength of this Polystyrene mold is between 5000 and 7000 Psi. It should be noted that this strength in high impact polystyrene is about 2.5 pounds.
Flexural Modulus indicates the hardness of the material. For crystalline polystyrene, it is about 450,000 Psi. While this parameter in High Impact Polystyrene is about 25000 Psi.
Manufacture of polystyrene mold
Manufacture of polystyrene
Polystyrenes are made in different molds. These polymeric materials are used in various industries. You see this all over the world! From medical and pharmaceutical supplies to food packaging and nylon bags. Careful tests must be performed to make PSs into the desired molds. For example, after molding, polystyrene must be removed from the mold. Molding methods are different and each has specific conditions for forming polystyrene.
The main features of polystyrenes
The most important properties of polystyrenes are their mechanical and electrical properties. These materials soften and deform after heating. Then, for molding, they enter different molds. Polystyrene mold is made in various ways. In addition, these polymers have very interesting properties:
- Polystyrene is used to produce glass and car parts.
- To produce plastics, thermoplastics that are melted at a certain temperature are used.
- To make polystyrene molds, they must be injected into various molds. Then the quality of the product must be controlled so that the produced polymer has a uniform structure.
- Melting temperature varies in different types of polystyrene grades. This temperature can lead to thermochemical changes in polystyrene.
- Adhesion is one of the properties of polystyrene. These materials are also used for painting; Because they easily stick to surfaces and paint different materials.
- The main ingredients of PSs are the same; But the various parameters that enter this material, make polystyrene have new properties. For example, in the production of HIPS polystyrene, the addition of butadiene increases the impact resistance. While in GPPS, the impact resistance is less and the material is more transparent.
- Temperature control is very important in the process of making polystyrene molds. This temperature control is done by thermal sensors. The best polystyrene is produced when the mold temperature is the same in all parts of the machine.
Summary of Polystyrene mold review
Polystyrenes are used in various industries to produce plastics. These materials are usually transparent and resistant to electricity, shock, and light. These materials have good adhesion and are used for painting different surfaces.
There are different molds for making different types of Polystyrene mold. In general, the ingredients of PS grades are the same; But the molding method for producing each polystyrene model is different. This different method of molding makes polystyrenes in different grades have different properties.
In PS molding tests, temperature and quality control must be performed continuously. This control is very important; Because the polystyrene produced must have all the necessary standards to enter the industry.
In this article from Petroproviders, we saw different types of polystyrene grades and different types of polystyrene mold. What do you think about these popular polymers? If this article was helpful to you, share it with your friends.
