Plastic

Plastics today go hand and hand with the lifestyles people live in the United States. Plastic is used in also every medium of my day, like many other people would agree, as its use is unavoidable. I use plastic for containers holding soap and makeup, mediums for food and beverages, and many others things. With plastic having so much prevalence today, it’s hard to believe that it can also have adverse side effects on the body as well. Phthalates are used in the production of plastic to allow it…

The chemistry behind polymers, the substance from which plastic is made, is very important in the everyday lives of the average person. To start, “The simplest definition of a polymer is a useful chemical made of many repeating units” (“The Basics”). Further, polymers are not limited to just plastics, but all types of plastic are polymers (“Plastics”). Some examples of polymers include cellulose and DNA (“Plastics”). Plastics are used everywhere in life today, and understanding the way that they…

fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process required the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. Figure 1: Injection molding. Injection molding is used to produce thin-walled…

Bisphenol A is widely used in plastics to form different types of materials for daily use in society. However these plastics such as containers, may expose people to small amounts of BPA in food and water. The exposure of BPA comes primarily from consumption of food, as there was a national survey given out by the CDC(Centers for Disease Control and Prevention) as there was BPA found in urine more than 90% of the people being studied. In one of the research articles, a team of scientist…

BPA (bisphenol-A) is an industrial chemical that is widely used in commercial products such as, hard plastic food and beverage containers as well as hygiene products. It is one of the most well-known and widely used chemical that can affect the endocrine system. BPA is an example of endocrine disrupting compounds (EDCs), which are chemicals known to disrupt and affect the normal functions of the endocrine system. (Fraser, D. 2012) It can also be used in baby bottles and in the lining of canned…

commercial chemical often used in the making of polycarbonates and epoxy resin. Polycarbonates are often used in the making of plastic food and beverage containers, such. Epoxy resin is often used in the lining of food cans and the tops of bottles. This is dangerous because it poses a threat to human health. Bisphenol A also known as BPA can seep through the plastic container and into the food or beverage itself. Exposure to BPA can have a negative impact on the reproductive system, the…

MANUFACTURING COSTS: Functional Elements: The baby stroller is mainly composed of three materials: Nylon (woven, as fabric) Plastic (injection molded, for plastic parts) Steel (tubing, for frame) Fasteners are included in the assembly of different components of the strollers. The stroller would have to be manufactured on an assembly line. The fabric weaving and seat making, the plastic molding and the frame can simultaneously be manufactured in their respective work areas. Following are…

Colorado, a land of exploration, attraction and individuality. A place where you can both walk the active city and experience the beauty of the Rocky Mountains. Somewhere you can drive through the fascinating architecture of Metro Denver. Somewhere you can sit and observe the glistening bodies of water, the rushing rivers and still lakes. Somewhere you can wander up trails to discover the top of peaks to find yourself with unbelievable views. Somewhere you will experience and never forget…

4.0.3. Plastics - Newer plastics are strong, good impact absorber and can be easily replaced when damaged. In the manufacturer’s side, because it has a lower melting point and also great malleability in comparison with metals so it is cheaper to produce. Plastics can be easily formed into shapes as required. They can be also coloured while it is being manufactured, saving time for another process such as painting. Plastics also tend to have faster cycle times and turnover rates. It is also…

The project that I will be testing and researching is if milk can create plastic and which acid creates the hardest plastic. I chose to do this project because it was very interesting to me and I thought that this would be a very interesting way to reduce the harmful gasses that we produce. Also if it works then this could be a thing that changes mankind by reducing pollution and helping the human race live a healthier life and maybe it would even help make the Earth live a little longer than…
