Types and types of plastics how to determine, application, characteristics

In today’s world, plastic is used daily. Unfortunately, people do not think what irreparable harm this product brings to our nature and how much it affects the ecological situation in the world. The only way out of this situation is to properly dispose of plastic products. In this case, you can not only save nature, but also reuse the resulting raw materials.

How to determine the type of plastic?

All types of plastic have a characteristic sign, which must be present on the product without fail. As a rule, such icons are located on the packaging. In order not to purchase a product that emits chemicals, you should familiarize yourself with the main types of plastic.

Types of plastics

Types of plastics can vary in chemical composition, stiffness, fat content. But still, the main feature is the behavior of the material when heated. Based on this criterion, there are the following types of plastic:

  • thermoplastic melts when heated, returns to its original shape when cooled;
  • thermoplastic in the process of heating they pass into an insoluble solid state;
  • Elastomers are a type of plastic with highly elastic properties.
  • Elastomers are considered the highest quality plastics.

    Plastic types

    Today there are many plastic products. Each type of material has its own characteristics, advantages and disadvantages. Consider the types of plastic we use in our daily lives:

  • PET or PET (PET, PETE) is polyethylene terephthalate; is a common type of plastic. It is used to produce disposable bottles, usually for carbonated and refreshing drinks. The main advantage of the material is water resistance. While glass is fragile and can break at any moment, plastic is many times lighter and more practical. In addition, the pluses include impact resistance, low cost and the ability to store large bottles.
  • HDPE (HDPE) is a high density low pressure polyethylene. This type of plastic has the main advantage it practically does not emit harmful components, it is recommended to store liquid in it. The material is durable, resistant to oils and other elements, low transparency. Durable durable plastic can be used to store a variety of foods, items and detergents.
  • PVC (PVC) is polyvinyl chloride; refers to hazardous types of plastic, as it releases two chemicals that negatively affect the user’s hormonal balance. The material is soft and flexible. It is most often used for the production of blister packages, storage of toys. PVC is used in the construction sector, pipes, garden hoses and parts for plumbing are made from it. Plastic is not environmentally friendly and only in some countries can be reprocessed.
  • PVD (LDPE) is a lowpressure lowpressure polyethylene. Most often, the material is used for the production of bottles and plastic bags. The bottles do not secrete chemicals, while it is better to refrain from buying packages. Products contain compounds dangerous for the heart of a person.
  • PP (PP) polypropylene white or translucent color. Distinctive feature of the material heat resistance. PP is considered safe and does not melt when heated.
  • PS (PS) polystyrene, with thermal exposure, involves the release of hazardous chemicals. As a rule, it is used for the production of coffee cups and food containers. The features of the material are affordable cost, light weight, durable plastic.
  • O (OTHER) other types of plastic.
  • It is recommended to study the types of plastic before buying products.
