Polymers that are manmade are simply called synthetic polymers. These are molecular chains that consist of multiple repeating units and these are the polymers. The human body contains also naturally occurring polymers and these include the human DNA and the body's many proteins. There are four main groups of synthetic polymers that people can manufacture.
Synthetic fibers are one type of synthetic polymers and these have many interesting common properties. They generally resistant to chemicals, fungi and insects do not absorb moisture. They also typically cost much less to produce than a natural fiber, so this is why these fibers are used to replace fibers such as natural silk. A few common types of synthetic fibers include nylon, spandex and rayon.
Polymers with high elasticity are the elastomers, also one type of synthetic polymer, one that is highly elastic, just like its name. Flexible products like shoe soles and tires are products made from elastomers. Silicone rubber which is used as a sealant is also one of the many different types of elastomers.
Thermosets is yet another category of synthetic polymer and this is also known as a thermosetting plastic. This is a type of polymer that is formed into a product or item using heat and once it has dried and set it irreversibly cured. This "cure" is applied during the heating process. Because these thermoplastics cannot be re-melted and formed into new shapes or products, they are not highly recyclable although sometimes they can be shredded or broken down and used to help make other items. One example of a thermosetting plastic is vulcanized rubber which is used to make tires.
Synthetic polymer products that sound similar to the thermosetting plastic products but with some differences are the thermoplastics. These are products that can be melted several times and reused because thermoplastics are products that do not go into a chemical change when heated. These are products that are recyclable but are not usually biodegradable, and these are mostly these thermoplastic products.
Thermoplastics are synthetic polymers used in making thermoplastic packages, and can run into millions each year. These are the custom packaging products made by many thermo forming companies. These are the water bottles and milk jugs and also the food containers used as food storage, made from thermoplastics. Aside from these custom made packages produced by the thermoforming companies, other products are made from this plastic type. One common type of thermoplastic is polyvinyl chloride, which is known simply as PVC and used to make many products, especially pipes.
