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.
3. POLYETHYLENE MATERIALS
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.

Learn about the general plastic used in u bottles: PET
PET Plastics are some of the more frequently discussed plastics when looking for solutions for drinking water. Unlike other types of plastics, polyethylene terephthalate is considered safe and represented on water bottles number "1", indicating that it is a safe option. These plastics are a kind of thermoplastic polymer resin that is useful in a variety of applications, including synthetic fiber production, in food containers and thermoforming applications.
It does not contain polyethylene - despite its name.
John Rex Whinfield patented PET plastics first in 1941, along with James Tennant Dickson and others working for the Calico Printers Association. Once created and found to be very effective, the production of products using PET plastics has become more popular. The first PET bottle was patented later in 1973. At that time, Nathaniel Wyeth created the first official PET bottle in this patent. Wyeth was the brother of a famous American painter named Andrew Wyeth.
There are some benefits from the use of PET plastics. Perhaps one of its most important features is its intrinsic viscosity. It absorbs water from the environment, which makes it hydroscopic. This allows the material to be processed using a common molding machine and is then dried.
It has an excellent abrasion resistance compared to other plastics.
It has high flexibility coefficient (makes it flexible.)
It has superior stability that makes it versatile and robust.
It has a low friction coefficient useful in various applications where other plastics are not available.
Plastic's chemicals do not leak into liquids or foods stored in it - making it one of the most important products for food storage.
Plastic's chemicals do not leak into liquids or foods stored in it - making it one of the most important products for food storage. These physical properties are an advantageous option for manufacturers who need safe plastics for use with food products or for continuous use.
Uses in Daily Life
There are both industrial and consumer-related uses for PET plastics. The most common use cases for polyethylene terephthalate are given below:
It is widely used in bottles and other plastic containers. This includes soda bottles, bakery products, water bottles, peanut butter jars, and even frozen food packaging.
It is used to hold cosmetics. As it is easy to mold, manufacturers can create very special shapes for various cosmetic products.
It is widely used for the storage of chemicals, including household cleaners.
Why do manufacturers turn to PET plastics when they can choose other types of materials that are easier to find? PET plastics are durable and strong. Many applications can be used repeatedly (recycling is a possibility with these products). It is also transparent and makes it versatile for a variety of applications. It can be closed again; easy to mold to any shape, easy to seal.
In addition, there is no possibility of shattering. Moreover, perhaps most importantly, it is a cheap type of plastic to use in many applications.
Recycling of PET Plastics Makes Sense
RPET plastics are a form similar to PET. These are produced after recycling of polyethylene terephthalate. The first PET bottle to be recycled occurred in 1977. As the main component in most of the plastic bottles used today, one of the most common discussions about PET plastics recycles it. It is an estimate that the average household produces about 42 pounds of plastic bottles containing PET annually. When recycled, PET can be used in a variety of ways for a variety of applications, including use on fabrics such as t-shirts and underwear.
It can be used as fiber in polyester based carpets. It is also effective as a fiber filler for winter coats and sleeping bags.
In industrial applications, it can be very effective for bonding or film and can be useful in creating automobile products, including fuse boxes and bumpers.
Polyvinyl chloride (Generally abbreviated as PVC.) A plastic polymer with a wide range of uses. It is the third most produced synthetic plastic polymer in the world after polyethylene and polypropylene.
It has two forms: solid (sometimes abbreviated as RPVC) and flexible. The solid form of PVC is used in the building industry for pipe and plumbing materials and door and window profiles. In recent years, PVC has taken its place in many fields of wood, concrete and clay, which are traditional building materials. It is also used in bottles, non-renewable product packages and cards (bank and member cards). It can be made softer and more flexible by adding plasticizers such as phthalates. This soft form is used in the wastewater industry in pipelines, electrical cable insulation, imitation leather, inflatable products. There are also application areas where it is used instead of rubber. It has been used in the health sector for the last 50 years. PVC can be found in the bags and transfusion sets, catheters, cannulas and drains, stoma products and many other places in the bags of blood, blood and blood products used parenterally.
How is PVC produced?
Polyvinyl chloride is produced by polymerization of monomer vinyl chloride. PVC is a hard plastic, plasticizers are added to make it softer and more flexible.
The history of PVC
Polyvinyl chloride was discovered by accident by Henri Victor Regnault in 1835 and Eugen Baumann in 1872 in two different forms in the 19th century. At the beginning of the 20th century, Russian chemists Ivan Ostromislensky and Fritz Klatte tried PVC with the German chemical company Griesheim-Elektron in commercial products, but rigid handling and polymer embrittlement ceased efforts.
In 1926, B.F. Waldo Semon from Goodrich company has developed a plasticization method by mixing PVC with different additives. This result gave the material more flexible and more easily workable, and the widespread use in the commercial field has been achieved in the near future.
Can PVC be recycled?
PVC can be recycled about seven times and its life is about 140 years. The international recycling code is indicated as "3".
