Polymer factory workers operate the machinery and carry out other routine duties in factories manufacturing plastics, rubber, adhesives and/or other polymer products. Polymers are used in the manufacture of a wide range of products, including tyres, stationary, sporting equipment and adhesives. Much of the work in manufacturing plants is automated and computer-controlled, with polymer factory workers responsible for setting up these machines and monitoring their performance using gauges and computer displays. They are also responsible for feeding in raw materials and checking the finished products for faults, such as cracks, burns, discolouration and other defects. In some cases they may pack products for shipping.
