What is oil?
Oil is a mixture of solid hydrocarbons in liquid and gaseous form which results from the decomposition of the dead bodies of unicellular organisms (zooplankton and algae) in sedimentary rocks at high temperatures and pressures; Crude oil or petroleum is found naturally underground and after extraction is converted into fuel and other products.
Petrochemical
The word petrochemical is composed of the two words petron and chemistry and its literal meaning is chemicals derived from oil.
– Petrochemical products can be divided into three specific categories;
– Main products such as: ethylene, propylene, sulfur, gasoline, ammonia and…, which are the basis of many other petrochemical products.
– Intermediate products that are produced from the main products and raw materials of factories producing final products; Polystyrene, polypropylene and…
– The final products that are used to make supplies and tools for public use, such as home appliances, industrial, plastic containers and…
HiPack ps
What is polystyrene: Polystyrene is an aromatic synthetic polymer of styrene monomer (a petrochemical) that is available in three types: ordinary, durable and expandable. Chemically, polystyrene is a long-chain hydrocarbon in which the variable carbon centers are attached to phenyl groups (the name given to ring benzene). The chemical formula is polystyrene (n (C8H8).
Heat-softenable polymers allow them to soften easily when heated and take various forms.
Durable polystyrene This type of polystyrene, abbreviated as high-impact polystyrene (HIPS), is impact resistant and is therefore used in the manufacture of utensils and the body of home appliances. The brand name of this material in the Iranian market is Hypec. Uses for the production of disposable tableware, sports equipment, toys, refrigeration insulation
Polypropylene pp
History of Polypropylene
The history of polypropylene is due to the polymerization of propylene and has been newly discovered compared to other plastics. Polypropylene was invented by Fontana in 1950 and is characterized by an irregular structure with high molecular weight. Propylene is a huge success in the industry and is made from polypropylene cosmetics, invented by Giulio Nata in 1954. Polypropylene is a single compound when methyl radicals are arranged on one side of the chain. In 1957, production of polypropylene under the brand name “MOPLEN” by Montedison began. After that, the production and trade of that product was started by other European, American and Japanese companies.
What is polypropylene?
Polypropylene (PP) is one of several derivatives of propylene (CH3-CH = CH2)
Polypropylene is a thermoplastic polymer that is used in a wide range of applications including film and sheet, blow molding, injection molding, food packaging, textiles, laboratory and medical equipment, pipes, industrial and construction applications, and automotive components. In addition, polymers made from propylene monomer are typically resistant to chemical solvents, bases, and acids. The characteristic code of this polymer is.
Crystal Gpps
Crystals (gpps) are transparent materials with a low crystallinity that can be used as a transparent substitute. Ordinary polystyrene, abbreviated as GPPS, which is used for general purposes. These polystyrenes have dielectric properties. Therefore, they are used in electrical applications. They have a high. GPPS homopolymer 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. And most of its consumption is the production of disposable tableware.
Crystal defects:
This plastic is fragile.
It has low UV resistance and is only suitable for indoor applications.
What is a masterbatch?
Masterbatch is a product in which paint powder (pigment) or other additives are optimally combined with each other in a base resin.
Masterbatch contains three components;
1. Polymer base
2. Additive chemicals
3. Active compatibility factor as player.
The masterbatch polymer base should usually be similar to the original injection molded plastic with a granular appearance.
Chemicals additives: To change some of the properties of polymers, masterbatch must use compounds that have these properties in their composition. Pigments and fillers are among the additives that are added.
Compatibility factor: By adding materials such as polypropylene and maleic anhydride, they adjust the compatibility of the compound with polymers.
Types of masterbatches:
Colored, white, black, filler
colorful: Many plastics and plastic and polymer parts industries need colored raw materials for their products.
White: White samples of this product are used in the preparation of light-colored materials, such as disposable bottles…
Black: They are made as a polymer base for painting for UV resistant products and have many applications, manufacturers of pipes and fittings, manufacturers of home appliances and…
Filler masterbatch: It is used to reduce the price and improve the properties of masterbatch, and calcium carbonate masterbatch, talc masterbatch, mica and other masterbatch can be mentioned as filler masterbatch.
