About Polietilen (PE)

About Polietilen (PE)

Polyethylene is one of thermoplastic polymer and the oldest family initially showed only low-density development and generating high-density, linear medium density polyethylene to three new species were added to the family.

Polyethylene is widely used today rather. Addition of new species, namely improvement of polyethylene from toys, household goods up to the many bags of cans are used in the field.

Durability of polyethylene, strong variation, with the advantage of easy workability and dielectric properties are used as very common nowadays.

Polymerisation reaction of ethylene, chemical products company in 1930, Imperial Chemical Industries 7ngiliz chance at found. But in the beginning, about 2000 occur under barlık very high pressures of these reactions can be easily applied technology to make the required years. Before long, mechanical and electrical properties to become aware of the polyethylene, began to be used for many different applications. Then, 1950 in li chemist K. Ziegler, under low pressure has developed a polymer reaction update. This method 1970's life in all types of expanded polyethylene, so that date from polyethylene, the world-wide has become the most widely used plastics. Garbage bags, dating back to the electrical insulation was used in a wide variety of areas.


Polyethylene by white, semi-permeable, and highly durable polymer that can be softened. Sold on the market, especially the transparent one. Transparency relates to the degree of intensity. As density increases, the transparency increases. According to the intensity in the market for polyethylene, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene (OYPE) and high density polyethylene (HDPE). In each of the four types of polyethylene and ethylene monomer, polymer molecules of different structures are emerging. Polymer molecules are composed of the chain molecules shaped macro provides a variety of different branching of the polyethylene case. For example, LLDPE at no branch will be less, HDPE 'a little bit more, OYPE at is greater. LDPE at branch level is maximum. Polymer properties that one is long or short Dal etkiler.Yoğunluk hardness and strength increases, so transparency increases, the softening temperature increases. This type of liquid to gas and also becomes difficult to affect.

Polyethylene is a polymer of participation. Ethylene, polymer and becomes a catalyst and polyethylene polimerlesmeyi initiator occurs. NCH

5.1. Oxidation PREVENTIVES

This type of chemical structure is generally fent as primary and secondary antioxidant is divided into two groups. In other words, radical extinguishers Primary oksidantlar polyethylene macromolecules during the heating and the resulting fragmentation of the radicals are neutralized, prevents proliferation. Secondary antioxidants in an oxygenated environment degradation of the polyethylene formed with parts and hidrosiperoksitleri More prevents decay. These two long-term degradation of polyethylene oksidantlar ensures against resistant.


Solar ultraviolet light cut all kinds of carbon - carbon bond, and this will impact causes bond breaking weaken over time. This is to move to the front of the sun into the effect of polyethylene polyethylene chemical substances that are placed before absorption. These chemicals, UV absorber and UV to quencher is collected in two groups.

Plastic Polymer-based, be processed in liquid form and organic matter formed after hardening. More oil is produced from raw materials of plastics. Small molecule chemical means combined with the monomers are polymerised and this is the result of large molecular polymers occurs. Polymer additives are added to many plastics suitable for the purpose is achieved.

Plastic easy workability, color, brightness, suitable for automatic production of, the plastic used in various fields has led to the possibility. Plastic also can be very cheap goods. Strength of climatic conditions are better than metal. Phone from the body and hands, utensils, floor covering, bottles, furniture, industrial tools and many other materials are manufactured from plastic.

Emergence of plastic: Very Sella Since ancient times, was used as resin materials such as plastic. Americans in 1868 as a synthetic plastic made John W. By Hyatt, cellulose nitrate was obtained by mixing with camphor. This plastic material billiard balls, buttons, combs were made. Yet in the year 1909 bakelite American explorers, known as Leo Baekeland Ho phenol formaldehyde polymer found. Du Pont company in 1935 from the nylon polymers find a great new epoch. In the meantime, Polyvinyl chloride (PVC) and acrylic plastics were made and have been used. Du Pont Company in the year 1938 finds the teflon will replace the nearly metal features. Under high pressure steam uncovered Tetrafloretilen white powder obtained from the 800 ° C temperature resistant Teflon and is very durable and flexible to use the expanded area. Max Planck Institute in Germany in 1950 in the low pressure under the researchers named Karl Zevger easily obtained and has produced high-strength polyethylene plastic.

Classification of Plastics: Plastics are divided into three main classes:

1. Cellulosic plastics,

2. Of course, plastics,

3. Synthetic resin plastics.

Three main classes of plastics also are divided into different classes between them. Between cellulosic plastic cellulose acetate, cellulose ester asetobütirat, cellulose esters can be considered. Casein plastics, natural and plastic, was manufactured from milk, also called for süttaşı. Synthetic resin plastics as thermoplastic and thermoset plastics are the two groups.

Be made of plastic material to be formed at a time is heated to soften the time (thermoplastics) and hardens after being heated once again softened even without heating (Thermosetting) is divided into two classes.

Acrylonitrile-bütadiyenstiren into thermoplastics (ABS) plastics, acetal plastics, acrylic plastics, cellulose plastics, florplastikleri, Polyethylenes, polypropylenes, Polyvinyl chloride enter. Thermoset plastics into the amino plastics, epoxy resins, phenolic resins, polyurethanes enters.

Plastics additives: Plastic main material is a polymer. To be shaped and painted to burn plastic, oil, for the purpose of increasing resistance to moisture and is attended by various additives. To increase the strength of most plastic glass fiber is used. To increase the vibration resistance, plastics into the rubber, and is attended by particles. To reduce the cost of plastic into the chip mamülün powder, mica and asbestos dust is mixed. Heat and chemical resistance of plastics to chemical additives also are provided. The hardness is set with plastic dioktilftalat and similar compounds. Chlorine and bromine, with plastic side will not feature win. Process the pigment coloring plastics and paints (pigments) and dyes are made. For example, titanium dioxide, plastics can be used to give white color.

Plastic forming methods: plastic shapes to, heating and pressing molds through various methods is given. Plastic materials for this purpose automatic looms were manufactured. Plastic molding is done in three main method. These injection molding, transfer molding and squeezing-compression (ekstrusyon) is a method. Apart from these methods, there are also many other special forming procedures.

Injection dump: the most widely used method of shaping thermoplastics are injection procedures. 3 mm-sized cubes or granules thermoplastics cylinder from a reservoir enters the melting box. Here, hydraulic pistons with plastic being melted with the electric heater is removed from the mold. All these operations are carried out automatically the injection machines.

Transfer Molding: Injection molding procedures to increase the speed of production in large amounts in the same genus containing male and female molds are used shape. This type of thermoset plastics, especially applies to the casting. Spills onto the female mold plastics, from finding more time to solidify a heated molding pressed men.

Crimping-compression molding: injection molding plastic mold with the hydraulic piston to push through the process of this method as well as meat machines can perform endless spiral gear. Electrically heated to melt the plastic granules passes through. Toothpaste with liquid plastic worm is transferred to the mold as bored. Mold cooling process can be done to obtain the shaped plastic material.

Blowing molding: hollow bottle-shaped plastics, plastic materials with compressed air into the mold to obtain inflated. Blowing molding method, large-sized containers, barrels, is suitable for the manufacture of automobile fuel tank.

Plastic coating: Liquefied heated plastic into the metal material is removed branch inexpensive, decorative products are obtained.

Linoleum production: Plastic material is passed between rollers takes the form of spread sheets. Tablecloths, shower curtains are made from this method.

Problems with Plastic: Plastic materials are used again after being melted into the new plastic material to join at a rate of 25 per cent by state can be available to cast again. For this type of resistance will decrease only job is used in plastics easier. In this way, the cost price of plastic materials can be reduced. Thermosetting plastics can not be used again being melted.

Plastic materials used to package the food, is a very sensitive matter who is requesting. Small molecules of plastic, preserved in the alcohol, acidic foods zehirliyebilir.

Plastic materials, porcelain, glass, metal materials is quite high compared to the rate of radioactive substances. Plastic materials have been stored in the field of staff pay attention to these matters will not be running. Plastic materials that cause environmental pollution as the most important matter is acceptable.
