thermosetting plastics would be used for recyclable things such as cans and plastics as they can be cleaned and re-moulded. These are used in times like today when global warming is affecting people and animals more than we think
Yes, polymers can be broadly categorized into natural and synthetic polymers. Synthetic polymers can further be classified based on their chemical structure and properties, such as thermoplastics, thermosets, elastomers, and fibers. These classifications help in understanding the different characteristics and applications of polymers.
Cyanoacrylate glue is a type of thermosetting adhesive. When it cures, it undergoes a chemical reaction that forms strong covalent bonds, resulting in a rigid structure that cannot be remelted or reshaped. Unlike thermoplastics, which can be reheated and reshaped, thermosets like cyanoacrylate are permanently set after curing.

Thermoset is a category of polymers that harden irreversibly when cured, while Bakelite is a specific type of thermoset resin made from phenol and formaldehyde. Bakelite was one of the first synthetic plastics and is known for its durability and electrical insulation properties. While all Bakelite is a thermoset, not all thermosets are Bakelite, as there are various other types of thermosetting polymers.
Thermoset plastics are rigid because their molecular structure undergoes a curing process that forms strong cross-links between polymer chains. This cross-linking creates a three-dimensional network that stabilizes the material, preventing it from softening or melting when heated. Unlike thermoplastics, which can be re-melted and reshaped, the hardened structure of thermosets gives them excellent mechanical strength and thermal stability. As a result, thermoset plastics maintain their shape and rigidity under stress and elevated temperatures.
Curing of a thermosetting polymer is irreversible.
There are two types of plastics: thermoplastics and thermosets. Thermoplastics, if exposed to enough heat, will melt. Thermosets will keep their shape until they are charred and burnt. Some examples of thermoplastics are grocery bags, piano keys and some automobile parts. Examples of thermosets are children's dinner sets and circuit boards.
depends which kind of plastic......e.g. we have thermoplastics and thermosets.
Single-Ply
In addition to thermosets, the specialty category also encompasses a relatively new category of rubbers called thermoplastic elastomers (TPEs). TPEs are often more economical to produce and easier to process than are thermosets.
There are a few differences between the two. Thermoplastics usually contain additives to change the properties of the material such as polypropylene. Thermosets usually contain catalysts that change the state of the material at the molecular level. The main difference between thermoplastics and thermosets is that: -Thermoplastics can be re-melted and recycled fairly easily -Thermosets typically are cured and molded into shape and are not recycled as easily
Plastics are available in two basic types: thermosets and thermoplastics. Thermoplastics are meltable, but thermosets are not. This is due to the types of polymers in the plastic. Because a thermoset type of plastic consists of three-dimensional chains of polymers they are stronger than a one-dimensional thermoplastic.
Examples of thermosetting plastics (or just thermosets) include amino, epoxy, and phenolic and unsaturated polyesters.
Thermoplastics are the only ones that can be recycled. Thermosets cannot be recycled.

A thermosetting plastic, in contrast, can be melted and shaped only once. If it is then heated a second time, it tends to crack or disintegrate. Examples of thermosetting plastics (or just thermosets) include amino, epoxy, and phenolic and unsaturated polyesters.
