What are Thermosetting Polymers?
Thermosetting polymers are those polymers that undergo a chemical change during the curing process that permanently fixes the polymer chains in place. This curing process usually involves the application of heat. Once cured, thermosetting polymers cannot be melted or reshaped. Thermosetting Polymers – Preparation Properties Uses and Examples.
Preparation of the Thermosetting Polymers
The thermosetting polymers are prepared by the polymerization of the monomers in the presence of an acidic or basic catalyst. The polymerization reaction is usually carried out in the presence of a solvent, which helps to dissolve the monomers and also helps to keep the catalyst in suspension. The polymerization reaction is usually allowed to continue until the desired molecular weight is reached. The polymer is then precipitated from the reaction mixture by the addition of a solvent that does not dissolve the polymer. The polymer is then dried and cured by heating to the desired temperature.
Properties Associated with Thermosetting Polymers
Thermosetting polymers are those that undergo a chemical change during the curing process, meaning they cannot be re-melted and reused. This change is typically triggered by the application of heat or ultraviolet light. Once cured, thermosetting polymers are typically very strong and durable, making them ideal for use in products like furniture, flooring, and automobile parts.
The Uses of Thermosetting Polymers
Thermosetting polymers are used in a variety of industries, including automotive, aerospace, construction, and electronics. They are used to make products such as car parts, insulation, electrical wiring, and circuit boards.
The Examples of Thermosetting Polymers
Some common thermosetting polymers include epoxy, polyester, and polyurethane. Thermosetting Polymers – Preparation Properties Uses and Examples.
