Plastics Technology Practice Plastics Technology Practice Objectives: To learn the practical applications of plastic technologies. To know the latest development of the plastic technologies. 1. Introduction In general term, plastic refers to the suitability for manufacturing and moulding into different shapes. Technically, plastics are polymers of high molecular weight by linking together many small monomers and may contain other organic, semiorganic or inorganic chemical substances to improve performance and/or reduce costs. Plastics are widely used in packaging, building & construction, transportation, communication, health, entertainment and many other industries for applications such as glazing panel, plumbing fixtures, helicopter blades, airplane fuselages, car bumpers, artificial hearts, food and drink containers, CDs, DVDs, electrical and electronic products. Plastics are useful but littering is not. It is estimated that everyday more than 60 million plastic water bottles are thrown away and most end up in landfills or incinerators in US. Plastics are non-biodegradable substance that degrade physically very slowly and prompt to pollute earth, air and water. On the other side of the coin, plastic packaging offers a superior ability to protect products against contamination; plastic pipes safely transport water or waste for their superior corrosion resistance and high strength to weight ratio; plastic vehicle parts consume less fuel for it weight to fuel impact; in electrical and electronics enable plastics to make our living easier, safer, less expensive and more fun for their ease of fabrication into complex shapes, insulation and colourful or transparent aesthetic aspect. Furthermore most plastics are petroleum base product and the energy required to produce plastics is just half of the energy required in producing paper and 1/5 in producing steel. Plastics can be firstly reused, replaced, and reduced and ultimately recycled at the end of their useful life. Plastic parts are littered because they are unfashionable rather than because they are worn out. Our living style is harming the earth not the plastics. Page 1 IC Professional Training
