usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film‚ pink or black forpolyethylene). The polyethylene variant may also take the form of foam or bubble wrap‚ either as sheets or bags. Because of the need for protection against mechanical damage as well as electrostatic damage‚ layers of protection are often used; because of this‚ a protected device can be packaged inside a metalized PET film bag‚ which is packed inside a pink polyethylene bubble-wrap

Different types of materials • Paper and Board Anything over 200g/m2 is considered a board. Corrugated card has two or more layers of card with a fluted inner section. This adds thickness and strength with very little increase in weight. Used for packaging objects which need protection during transportation. Cartridge paper / Photocopy paper is used for design drawings‚ sketches and good quality marker pen presentations. The surface is good for pencils‚ pens and markers‚ and is soft enough

profoundly changed the quality of life in the modern world. It is estimated that about half of all industrial research chemists are involved in some aspect of polymer chemistry. Few of us have not heard of nylon‚ rayon‚ polycarbonate‚ polyester‚ polyethylene‚ polystyrene‚ Teflon®‚ Formican®‚ and Saran‚ all of which are synthetic polymers. The technological impact of polymer chemistry is immense and continues to increase. ̣ ̣ The product of this step is also a free radical that can react with

manufacturing company located at Botany‚ NSW. The role of a plant chemist working in the polymer industry is concerned with the conversion of ethane to ethylene and the polymerisation of ethylene to polyethylene. Examples of their tasks are: • Monitoring the quality of the ethylene and polyethylene products‚ particularly checking for impurities • Monitoring waste-water from the production process to ensure that environmental standards are being met • Adjusting operating

Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene (HDPE). Polypropylene is normally tough and flexible‚ especially when copolymerized with ethylene. This allows polypropylene to be used as an engineering plastic‚ competing with
