PVC: Resins, products and recycle code   Following polyethylene and polypropylene, polyvinyl chloride (PVC) is the third most widely used worldwide. In construction, PVC is fast replacing traditional building materials such as rubber, clay, wood, concrete, glass and metal. The first preparation of PVC was in 1935 by a French chemist, Henri Victor Regnault but was patented in 1912 by a German chemist, Freidrich Heinrich August Klatte. The first commercial production was done in 1926 by Waldo Lunsbury Semon while working for the US Company, B. F. Goodrich.   The product of his work is what is known as plasticized PVC today. Polyvinyl chloride is a thermoplastic that is generally white in colour, brittle, solid, odourless and quite popular. Available in pellets and powder form, its versatility cuts across numerous applications such as: Applications of PVC -           water pipes (drinking, waste, irrigation, industrial) -           garden hoses -           roofing and flooring

Different PET products For every container used for soft drink and water, shampoo and liquid soap, cooking oil, food dressing and spread and; For every oven food tray, roasting bag, curtain, upholstery, thread, tyre cord filament, industrial fibre, and industrial filtration fabric, you are more than likely looking at a plastic product made of Polyethylene terephthalate. Still in doubt? Look for the inscription “bubble” or the recycling code “1” encased in a triangle of chasing arrows on the container or the item itself and, there you have it! You have identified a polyethylene terephthalate AKA PETE AKA PET! Polyethylene Terephthalate recycling code and acronyms Background The very first preparation of PET was made during a 1940 study of phthalic acid by Rex J. Whinfield and James T. Dickson of the Calico Printers Association, England. However, the war at the time delayed the publication of its patent specification. This stalled the production of the Terylene fibre by Imperial C
