Linear low-density polyethylene

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

handle, low in cost, less in weight etc. Approximately, 30-35% of milk is used in direct form, rest of milk is packed in various packaging form, like Glass bottle, Plastic bottle, Tetra pack, plastic pouch etc. As per data from total milk production 146.3 million tons, approximately 40 million tons milk is used for packaging milk for drinking purpose. This milk is packed in half litter and one litter pouches, which are made of conventional plastics (Low-density polyethylene and Linear low density polyethylene)

PHASE BEHAVIOR:- Melting Point:- The temperature at which polymer transmit into crystalline form to determine the melting point. The polymer of low-molecular substance exist very low melting point and this happened when polymer chain is dispersed. In physical state melting point is very difficult to calculate. Polymer will decompose at high temperature rather than melts. It is also known as crystalline melting temperature. Glass Transition

mechanical properties, crosslinking agents I. Introduction Thermosets are commodity as well as engineering plastics. They account for more than 70% of the total plastics market share. Though they are easily processable and available at relatively low cost, they involve cross linking process (curing) so as to become suitable for the application. There are certain disadvantages associated with processing of thermoset category of plastics like high amount of flashes, mold material abrasion at relatively

Ethics: The bridge we have created is ethical in the sense that it has a dependable purpose relative to its location, and its uses. By implementing a floating bridge, in a non-linear terrain in the city of Champong Chnnang it allows for effective, and efficient commute between two villages. This idea allows for the saving of time and money, by not implementing a less efficient method of transportation and trade between the two villages. THIS ISN’T GOOD ENOUGH, LET EDWARD ADD SHIT TO THIS TOO.

world consistently demonstrated that plastic materials make up 60-80% of marine debris. That little dolphin or penguin who accidently ingests that one plastic bag will die a slow death because they didn’t know better. One of the sites that have a density of 700 plastic debris is the North Sea in Europe. Currently, only Ireland has banned plastic bags and the United Kingdom put a 5-pound tax on plastic bags. All the other states surrounding has done anything about it yet. This is not okay because plastic

Strain 4. Procedure (Determination of Tensile Properties) 4.1 Materials General Purpose Polystyrene (GPPS), High Impact Polystyrene (HIPS), High Density Polyethylene (HDPE) and Polypropylene (PS). 4.2 Equipment Lloyd Tensile Testing Machine 4.3 Steps 4.4 Experimental Precaution: 1. Check the force that is applied in the load cell is correct. 2. Take into account the zero error when measuring

utilises a children 's roundabout or merry-go-round for a unique water solution. As children play and rotate the roundabout (1), it is designed to pump water by using a conventional pump (2) from an underground borehole (3). Water is pumped to a polyethylene water tank (4) located 7m above the ground, where water can be stored for future collection. Access to the water is from a nearby tap (5). If the tank is completely full, excess water is diverted back into the borehole via an overflow pipe (6)

prekinetic aggregation. The rate of aggregation in such cases would be determined by the frequency of collisions as well as the chances of cohesion during collision. Differential sedimentation assumes importance when particles of varying sizes and densities settle in a suspension. Faster settling particles collide with the slower moving ones, thereby resulting in aggregation. Lastly, the orthokinetic aggregation mechanism describes the aggregation brought about by increased particle collisions, arising

Dc conductivity and dielectric spectroscopic for PVA-Ag nanocomposite films The influence of gamma irradiation on the electrical and dielectric properties of AgNO3/ PVA films was investigated. The films were prepared by casting techniques, then irradiated with different gamma doses (25, 50, 75, 100, 125 KGy). The content of the Ag in the PVA film were determined by using atomic absorption spectroscopy (AA), and were found to be 0.4 wt %. The films have been characterized through dielectric spectroscopy
