The CSS450 was used to study the the phenomenon of flow-induced crystallisation. They are produced or synthesized from simple, oil-based raw materials known as monomers. Thermal transitions temperatures are where the polymers change their state from one form to another just as H2O (not a polymer) is solid below 0 deg C, liquid between 0 and 100 deg C and gas above 100 deg C. In polymers there are three main types of such transitions temperatures. Wool, cotton, silk, wood and leather are examples of natural polymers that have been known and used since ancient times. Rubbers and polymers based on one monomer are called “homopolymers”, … As their properties are so rich and diverse, it is essential to characterise and understand their behaviours under different environmental conditions. Overview; What is a Polymer? Processing plastics - molding Injection molding Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost. The environment within the chamber can also be controlled with the option of gas purging, controlled vacuum, pressure or humidity. Major chemical companies use base chemicals to produce polyethylene for packaging films, bottles and containers; polypropylene for manufacturing packaging, appliances, clothing and carpeting; polyvinyl chloride for producing piping, construction materials and packaging; polystyrene used in packaging, toys, recreation and appliances.
