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.
Thermosetting plastics are commonly used to make items such as electrical insulators, automotive parts, kitchenware, and durable industrial components like pipes and fittings. They are chosen for their high heat resistance and ability to retain their shape and strength even when exposed to high temperatures.
Examples of thermoplastics are-
- polythene
- polyvinyl chloride , etc.
Examples of thermosetting plastics are-
- melamine- used for making fire ressistant fabrics and floor tiles.
- bakelite- used for making cookware, insulated handles of utensils and dinner set.
The plastic containers that are used for keeping food, plastic Christmas decorations, hard plastic pens.
Epoxy resins (when cured) are thermoset. Polyesters used in car-body fillers are also. Polyurethanes and alkyd resins are also thermoset.

What does thermosetting plastic mean?
Thermosetting plastic refers to a type of polymer that, once molded and cured, cannot be reshaped or softened by applying heat. This is due to the cross-linking of polymer chains during the curing process, creating a rigid and durable material. Examples of thermosetting plastics include epoxy resins and phenolic resins.
Is a keyboard made from thermosetting plastic?
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.
What things made by thermoset plastics?
Thermoset plastics are used to make items like electrical insulators, circuit boards, automotive parts, and coatings due to their heat resistance and durability. They are also used in aerospace applications, construction materials, and various consumer goods.
Is it true that thermo softening plastics tend to break easily?
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.
How does the structure of a thermoplastic differ from a thermosetting plastic?
Once 'set' these plastics cannot be reheated to soften, shape and mould.Thermosetting Plastics are made up of lines of molecules which are heavily cross linked. It creates a rigid molecular structure.They may be heated the first time and shaped but they become permanently stiff and solid.Unlike thermoplastics, they retain their strength and shape even when heated.
What can you make out of non thermoplastic?
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.
Explain why saucepan handles is made of thermosetting plastics?
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.
What objects are made out of thermo plastics?
Examples of thermosetting plastics (or just thermosets) include amino, epoxy, and phenolic and unsaturated polyesters.
How is thermosetting plastic made?
it is made from things that u can use
Why is car tire a thermosetting plastics?
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.
What type of plastic are bottles made out of?
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.
What does thermosetting plastic mean?
Thermosetting plastic refers to a type of polymer that, once molded and cured, cannot be reshaped or softened by applying heat. This is due to the cross-linking of polymer chains during the curing process, creating a rigid and durable material. Examples of thermosetting plastics include epoxy resins and phenolic resins.
What plastics are thermosetting plastics?
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.
What is made out of thermosetting?
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.
Is a keyboard made from thermosetting plastic?
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.
What things made by thermoset plastics?
Thermoset plastics are used to make items like electrical insulators, circuit boards, automotive parts, and coatings due to their heat resistance and durability. They are also used in aerospace applications, construction materials, and various consumer goods.
Why are cooking spatulas made from thermosetting plastic and not thermoplastic?
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.
