Chemical resistance : Plastics are generally less susceptible to damage from chemicals or chemical reactions, such as oxidation or rusting, than metals. This is the main reason that plastic is commonly used in construction. Remote controls, computers, TVs, kitchen appliances – you name it and chances are it’s made of plastic. Plastics have actually been used in cars since the 1950s, but it’s the latest innovations that are really changing the industry for the better. These advantages are quantified in Table 1.2 where, for example, it is seen that nylon has a specific gravity about one-sixth that of … 1. Resistance to a wide range of chemical agents including acid rain and salt spray, conditions under which metal parts would suffer. Apart from weight and cost, plastic parts have the following advantages compared to metal parts. Lower electrical and thermal conductivity. Plastics can not be used for very high and low temperature ranges. This low weight means much less raw materials and less impact on the environment if using plastics over metals. One of the main advantages to using plastic as a construction material is the cost to produce and use plastics – it is less expensive than most other materials. Different parts require different injection molds. New plastic materials offer strength and stiffness comparable to steel, and innovative processing capabilities allow us to machine plastic parts with tight tolerances. Plastics typically come from non-renewable resources. Can have higher tensile strength vs. many types of metal. What was missing from the article, and from Dietrich's report, was commentary on the substantial economic and health benefits that come from the use of plastic pipe over conventional metal pipes. Additionally, overall part weight is reduced and the manufacturing process becomes more efficient by going with plastic over metal with minimal secondary operations needed. How designers across multiple industries are reducing costs and increasing profits by incorporating plastic instead of metal in new product designs. In Thin layer Chromatography also called (TLC) is widely used method for the separation and detection of an molecule from a given mixture of compounds..
