There may be confusion with the names of some materials. For example, many are interested in how plastic differs from plastic. The townsfolk are at a loss to guess whether one or two different substances are being discussed. Let's try to figure it out.
In any case, in both the names have a part "layer". It indicates the property of materials to form when heated and solidify in a given form. The density of plastics (plastics) is low, and the strength is relatively low. Substances are not conductive. When burned, they release toxins.
In fact, the difference between plastic and plastic can be traced only at the level of the tongue. In other words, the meaning of these names is the same, just the variant "plastic" is abbreviated. The materials in this category include polymers. They can be of natural origin, but synthetic products are especially widely used. The first plastic was called parkesin at the suggestion of its inventor Parkes.
Types of plastic (plastics)
Polypropylene. It is a solid material that is used to make food packaging, toys, garden furniture, disposable syringes. Automotive equipment is also made from it: bumpers, headlight parts, pedals. Polypropylene products are not destroyed by boiling and steam sterilization. If you melt the material, you can pull a long thread out of it with a match.
Polyethylene. Its types, characterized by high density, are used for the production of a variety of containers: bottles, cans, flasks, barrels and buckets. Pipes for communications are also made from materials in this category. Polyethylene with a lower density has film-forming properties and is in demand, for example, in the manufacture of packages for tea packs, garbage bags, tarpaulins.
Polyvinyl chloride. Such plastic is distinguished by its elasticity and resistance to various aggressive substances. It is used to produce electrical insulating casings, artificial leather, gramophone records and floor coverings in the form of linoleum. The products emitted from the combustion of PVC are highly toxic.
Polystyrene. A thin strip of this plastic bends easily and then breaks with a bang. Examples of such products are yoghurt cups, disposable tableware components.
Let's summarize. What is the difference between plastic and plastic? It consists only in the way of word formation. The first version of the name is abbreviated, the second is full. Both concepts denote a whole class of materials with specific properties and purposes..
