Epoxy is a good example Or rubber. Basically any plastic that transforms with heat, and cant be transformed back.
Thermosetting plastic or epoxy is a compond that when heated will cure and maintain it's shape even when heated again. Usually the compaound has to be mixed with hardeners and fillers then heated. Once cooled they will remain hard even if re-heated.
the structure of thermosetting plastics are Ø Thermoplastics have long chains which are tangled together in no formal pattern Ø They have very few cross links which means that when heated they become soft allowing them to bent, pressed and formed into different shapes. Ø They become stiff as they cool
No, keyboards are typically made from thermoplastic materials such as ABS or polycarbonate. Thermosetting plastics, once formed, cannot be reshaped or remolded like thermoplastics can be, making them less suitable for manufacturing keyboards.
Correction tape is typically made from thermoplastic materials, as these can be easily melted and reshaped when heated. Common components include a plastic film and an adhesive, both of which are thermoplastics. In contrast, thermosetting plastics cannot be remolded once they have cured. Therefore, correction tape does not fall into the thermosetting category.
There are almost countless numbers of things made from thermosetting plastics. Just a single example are the plastic forks, knives and spoons that we consider as "disposable" or "single use" utensils.
Thermo softening plastics have a lower melting point, making them more susceptible to deformation when exposed to heat. This can lead to a decrease in mechanical strength and make them more prone to breaking under stress compared to thermosetting plastics.
Many things are made out of "Non Thermoplastics", which are called Thermosetting Polymers. Basically there are two kinds of Plastics: Thermoplastic, which are heated and injected under pressure into molds to create new items. These are plastics that get soft when heated. And Thermosetting Polymers that are resins that are either combined with a substrate or used alone, then poured into a mold, then subjected to heat and pressure to create items or sheets. These are plastics that get hard when heated. Things that are made from Thermosetting Polymers (Non thermoplastic): sheets of fiberglass and phenolic out of which circuit board found in computers are made from, knobs, wheels, etc.
Thermoplastics can be reheated and reshaped, however Thermosetting plastics undergo a chemical change resulting in them becoming permanently rigid, i.e they cannot be reheated and reshaped.
Examples of thermosetting plastics (or just thermosets) include amino, epoxy, and phenolic and unsaturated polyesters.
it is made from things that u can use
Car tires are generally made from thermosetting plastics like vulcanized rubber because they can maintain their shape and integrity under high temperatures and mechanical stress. This makes them durable and able to withstand the harsh conditions on the road without deforming or softening. Additionally, thermosetting plastics offer excellent resistance to wear, abrasion, and chemicals, making them ideal for use in tires.
There are two types of plastics: thermoplastics and thermosetting polymers. Thermoplastics are the plastics that don't undergo chemical change in their composition when heated and can be moulded again and again; examples are polyethylene, polystyrene, polyvinyl chloride and polytetrafluoroethylene (PTFE).[3] Thermosets can melt and take shape once; after they have solidified, they stay solid.
the structure of thermosetting plastics are Ø Thermoplastics have long chains which are tangled together in no formal pattern Ø They have very few cross links which means that when heated they become soft allowing them to bent, pressed and formed into different shapes. Ø They become stiff as they cool
Thermosetting plastics are a type of plastic made of long, cross-linked molecule chains. Their structures are very rigid. Thermosetting plastics can be moulded and shaped when heated, yet they cannot be heated again after they set.
The most familiar use of thermosetting plastic is the heat-resistant handle on metal cookware. It is also used for bottle caps, knobs and handles, and laminated counter tops. Thermosetting plastics retain their shape and strength even when heated.
No, keyboards are typically made from thermoplastic materials such as ABS or polycarbonate. Thermosetting plastics, once formed, cannot be reshaped or remolded like thermoplastics can be, making them less suitable for manufacturing keyboards.

Cooking spatulas are made from thermosetting plastic because it can withstand high temperatures without deforming. Thermosetting plastics undergo a chemical change when heated, leading to a rigid and heat-resistant material. This makes them ideal for use in cooking applications where high temperatures are common.
