going to see the polymers use in Exterior trim in Automotive, discuss the advantages and disadvantages, and see some examples on polymer used in Exterior trim but first What is the Exterior trim? It is any part use on the outside body of the car to protect other parts or just to add aesthetic look on the car like bumpers, car tyers and door handles...….etc. The figure below show some exterior part made of plastic: (Plastic still has a poor image even today, being connected more with flimsy toys

The term plastic came from the Greek word plastikos, this word means “fit for molding.” Plastics have many different properties when observed as a total.

international bank HSBC warned that less than 50 years' supply of oil is left. And for the second disadvantage, many synthetic polymers' most desirable feature is their chemical inertness -- their resistance to various kinds of chemical degradation. This same property, however, also means they last a long time once they are thrown away. According to a 2007 article in Slate, scientists estimate that a single plastic bag could take as much as 500 years to break down. This is heavily related to the factor of
entrepreneur, was able to invent a way to make a bioplastic out of the starch from cassava, vegetable oil, and organic resins, which is a highly viscous substance that has traces of plants and other organic materials. He realized that no matter how much plastic is recycled, it is eventually going to end up in one place: the landfill. Additionally, an apparent way to improve recycling is to educate the people of this world about the hazardous effects of not recycling and trashing the environment. “By educating
made up of plastics around you. Plastic plays a big role in our environment. Not only does plastic replace materials such as paper, metal, etc. But it also has new roles only it can fill. It can be used to make bottles, cans, supermarket bags, plastic bottles, etc. The word plastic itself comes from the word ‘plasticos’, which means to be shaped or molded by heat.

types: Depending on your application, you should choose the right piece of material to fulfill your specific requirements. Each type comes with advantages and disadvantages. For example, metal products are strong, but cannot be used for applications such as electrical wiring (metal is a conductor of electricity.) Anyway, metal pieces are more durable than plastic ones. So, you should understand the strengths and weaknesses of each type and choose the right one for your application. Below is a list of

The other sub components that included into Dexter’s’ design were plastic wheels and LCD display as information viewer for debugging and testing the performance while exploring in the Maze since in reality cant direct find out the error that shown by the software instruction and just can be view through the assistance of
Who is benefiting the most out of this? We as humans are benefiting the most out of this, because we get a good quality of life. It also benefits Canada, because extracting natural resources creates wealth for this country. This creates quality of life for us human beings, because we use oil to drive cars and many other things. Also it creates work jobs. A lot of people in Canada are currently working in natural resource sectors. Meaning creating 10 percent of all jobs in Canada. Natural resources
