What type of plastic is pet?

Answer 1

PET, polyethylene terephthalate, is a condensation polymer and a thermoplastic.

Among different plastics, there are two primary types of plastics called thermoplastics and thermosets. Plastics are placed in one of these two categories based on their reaction to heat. On a chemical level, heating does not change the bonds in thermoplastics, which means that thermoplastics can be melted and molded again and again. As for thermosets, heating past a certain degree will cause curing, which is when the polymer chains of the plastic start linking with each other (cross-linking). This phenomenon makes it so that thermosets can be melted, molded, and solidified only once. After the initial melting and reformation, the plastic's shape cannot be altered.

The other classification used for plastics is based on the type of reaction that occurs when monomers of the plastic are bonded together. The creation of addition polymers involve addition reactions that rearrange the configuration of the chemical bonds within and between the monomers. On the other hand, condensation polymers are the result of condensation reactions where each bonding of the monomers of the plastic releases water molecules.

Hence, PET is a thermoplastic that can be melted and molded repeatedly (making it recyclable) and a condensation polymer that releases water molecules when monomers of it are bonded.

Answer 2

In the context of a plastic, PET stands for polyethylene terephthalate. It is a thermoplastic polyester. Being a thermoplastic means that it softens when heated above a specific temperature and can be formed into shapes that it retains when it cools. PET is the most common of the thermoplastic polyesters and is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.

Answer 3

No, that is typically a dog or a cat. You can get plastic pets, but I dont think they are really considered real pets.
