Thermoplastics are plastics that can be melted and recycled. Thermoplastics are used for many objects such as bottles, bags, records, hoses, clothes, containers, etc. There are a variety of different types thermoplastics and can have many different qualities to combat the environment. They are different from "thermosetting" plastics in this way.
Thermosetting plastics are typically heated and compressed in a mold to achieve a desired shape or mixed from a resin and a hardener as used for composite material. When they are in contact with high temperatures they burn instead of melt, which is why they cannot be recycled. They are generally used for kitchen utensils like a spatula but are often used for telephones, computers etc.

thermoplastics and thermosetting plastics thermoplastics go soft when exposed to heat thermosetting plastics set (harden) when exposed to heat only thermoplastics are recyclable
Thermoplastics are the only ones that can be recycled. Thermosets cannot be recycled.
By properties they are Thermosetting plastics and Thermoplastics
i think the answers you are looking for are thermoplastics and thermosetting plastics :)
Thermoplastics are polymers that can be molded above a certain temperature. They are needed to manufacture such plastics as acrylic, nylon and polystyrene.
Thermoplastic plastics melt when heated and therefore can be easily molded and recycled. In comparison, Thermoset plastics utilize a chemical reaction to cure and irreversibly set.
thermosettings and thermoplastics. A thermoplastic can be remelted and reused, a thermoset cannot.
