Bitumen is the thickest form of petroleum there is, made up of 83% carbon, 10% hydrogen and lesser amounts of oxygen, nitrogen, sulphur, and other elements. It is a natural polymer of low molecular weight: at lower temperatures it is rigid and brittle, at room temperature it is flexible, at higher temperatures it flows.
The soda bottle so common today is made of Polyethylene Terephthalate (PET) , a strong yet lightweight plastic. PET is used to make many products, such as polyester fabric, cable wraps, films, transformer insulation, generator parts, and packaging.ext, the dimethyl terephthalat, is combined with an excess of ethylene glycol at 305 degrees Fahrenheit (150 degrees Celsius) to yield another substance, bis 2-hydroxyethyl terephthalate and methanol. The final step of polymerization involves the condensation polymerization of the bis 2-hydroxyethyl terephthalate.
