Due to the high technology of plastic injection molding machines, polymer is one of the most used raw materials for the transformation of plastic. This resin is formed by several monomers and can be divided into natural or synthetic. Nevertheless, what are the uses of polymers?
These compounds contribute positively in the manufacture of products that optimize day-to-day activities and improve our safety. Do you want to know more about it? In this content, you will see what are the uses of polymers, as well as its advantages and applications. Keep reading!
Polymers function
With the countless technological advances, the polymeric industry has become increasingly important in maintaining the contemporary lifestyle. No wonder, it is very common for the uses of polymers to be part of the plastic, civil and textile industry, besides many others.
This happens for the reason that these materials enable the development of products with innovative chemical characteristics, such as polyvinyl acetate (PVA), used in coatings. It can also contribute positively in the production of nylon, being an example of polymers in clothing and fibers, and polyvinyl chloride (PVC), used in the pipes.
These polymers used in everyday life only have these functions on account of polymerization, a process in which the smaller molecules (monomers) come together to form long molecules. Furthermore, it can be formed by chain reaction or through chemical reactions, such as polyaddition or polycondensation.
In a simplified way, the first is a polymerization responsible for obtaining large polymers by means of double bond monomers. The second is a process used in non-vinyl monomers, that is, when the molecule is formed through the condensation between the same or different materials.
Polymers applications
Having understood the uses of polymers, the next step is to know what are the options available on the market and the applications of each one. With that in mind, we have some examples of polymers in everyday life, such as civil construction, automotive sector, communications, among other fields. Check out!
Polycarbonate (PC)
Polycarbonate is a long-chain compound, formed by functional groups linked to carbonate groups. It is considered thermoplastic, since it can be molded when heated. The main applications of this compound are in CDs, filter containers, bottles, showcases, partitions, etc.
Polyurethane (PU)
This polymer is composed of a chain of organic units connected by urethane links. This option is widely used in metal sheets, car upholstery, thermal insulation in waterproof clothing, casing, coatings, films, belts and frames.
Polystyrene (PS)
Polystyrene is a homopolymer formed by the polymerization of the styrene monomer. It is also part of the thermoplastic polymers examples, which gives it greater flexibility. It can be used in the manufacture of thermal insulation, air-conditioner fan cover, and toys, as well as machine and automobile parts.
Polyvinyl chloride (PVC)
Polyvinyl chloride is one of the most produced synthetic polymers in the world. It can be characterized as rigid or flexible. Its main applications are in partitions, translucent roof tiles, pipes and connections for water, window blinds, sewers and ventilation.
Polypropylene (PP)
Belonging to the group of polyolefins, polypropylene, also called polypropene, is a thermoplastic compound produced by polymerization by adding the propylene monomer. It can be applied in containers for food, chemicals, fibers, oriented films, hospital material, among others.
Polyethylene terephthalate (PET)
Finally, polyethylene terephthalate is a thermoplastic composed of the reaction between ethylene glycol and terephthalic acid. In general, this polymer is applied in the manufacture of wires, fabrics, beverage packaging, cleaning products, brooms, food, soft drinks, and others.
Polymers and recycling processes
One of the problems in today’s society is the generation of waste. Thus, with the increase in the use of polymers, this agenda has become important. This is considering the methods of decomposition and collection of materials are not efficient. Do not worry yet: biodegradable polymers in everyday life can be good solutions.
Even so, what are biodegradable polymers, and what is it for? While it is not recyclable, it is excellent for companies looking for alternatives that contribute positively to the health of the environment. This is only possible due to these compounds being non-polluting and not needing special disposal.
