Low-density polyethylene

MATERIALS CHRACTERIZATION: 1. Tensile Testing: Tensile test for composites was conducted according to ASTM D 638 - 99, with a Universal Testing Machine (Zwick Co.). Tensile test was carried out at crosshead speed of 50mm/min at room temperature. 2. Izod Impact Testing: In order to measure the work of fracture (WOF), the Izod impact test was carried out.Impact bars were obtained by cutting specimens in rectangular shapes. These rectangular specimens are of thickness 3 mm, width 12 mm and length

quality the second time it is used. Polyethylene plastic was accidently discovered through experiments many years ago and it can now be found in about everything we use in the modern life today. It is the most popular plastic in the world today.

polystyrene and polyethylene (Shakhashiri). Polymers are synthesised using a chemical process known as polymerisation, where individual molecules called monomers are reacted to form chains or three dimensional networks. A look at the history of polymers reveals that many of the first discoveries were accidental. Since these discoveries, a whole new area of chemistry

is Thermal cracking and other is Catalytic cracking .we have compare the result obtain from both cracking. In the catalytic cracking we have use Aluminium silicate as a catalyst. also we have taken a test like flash point ,pour point, viscocity,density of both fuels oils obtained.

I.Introduction The disposal of waste plastic a major environment problem all over the world. due to excessive

EFFECT OF KAOLIN ON THE MECHANICAL PROPERTIES OF POLYPROPYLENE/ POLYETHYLENE COMPOSITE MATERIAL Samir Nassaf Mustafa ABSTRACT :- In this work, the mechanical and water absorption properties of polymer blend polypropylene (PP) and low density polyethylene (LDPE) at constant ratio (50/50) composites as a function of kaolin powder weight content in the grain size (100,120 µm) were investigated. Polymer composite was fabricated by mixing polymer blend ( PPLDPE) with (0, 1, 3 ,5, 10, 14) wt.% of kaolin

(PBB) because it was being privatized by the government of Argentina. PBB, which is located in Bahia Blance, is a major producer of both ethylene and polyethylene in Argentina. Dow sees this as a very big opportunity for the company to expand its market, utilize its resources and invest on a company that will eventually become the leading polyethylene player in Latin America. Dow’s vice president of business development for Latin America, Oscar Vignart, and Luis Marcer, CFO of Dow Química

952). Low-density polyethylene is very thin and stretchy, while high-density polyethylene is stiffer, more durable and has a higher melting point than its low-density counterpart. Both of these types of polyethylene are used to create many different items of plastic, including pipes, toys, and the one that consumers use every day in grocery stores: the plastic

elements appropriately to achieve a system with structural or functional characteristics of the best that can be achieved through one of the components alone. The vehicle has become an essential part of the day because of the material advantages such as low weight, high corrosion resistance, high strength and fatigue, and faster assembly. Used widely as raw materials in the airframe industry, packaging, electronics, medical equipment and spacecraft building materials home [1]. The increased use of composite

Question 1 Polyethylene is the world’s most widely used plastic. Polyethylene plastic’s principal application was in packaging, from trash bags to milk jugs. It was widely used in the manufacture of everything from trash bags, picnic cutlery and garbage pails, to plastic toys. Polyethylene also replaced glass, wood, and metal in certain applications. There were three types of polyethylene, Low-density polyethylene, High density polyethylene and Low linear density polyethylene. Polyethylene produced
