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. 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
