Thermoset plastics are synthetic materials which undergo a chemical change during processing to strengthen and set them into a form. Examples of thermoset plastics include epoxy, silicone, amino, phenolic and unsaturated polyesters.Know More
Thermoset plastics are contrasted by thermoplastics, which soften when heated and strengthen and set into form as they are cooled. Thermoset plastics have a net-like structure of cross-linked polymers. Once they have undergone the initial chemical change during processing, they cannot be melted or remolded. They are also resistant to solvents.
Because of these basic properties, thermoset plastics are inherently strong and durable even under high-heat conditions, although they are somewhat brittle. These plastics are often used to make large and/or permanent parts or shapes such as automobile bodies. They are also used in electronic chips, polymer coatings, the coatings on eyeglasses and in dental fillings. Vulcanized rubber is another example of a thermoset plastic material.
Thermoset plastics are typically produced by heating a powder or liquid in a mold. The chemical change that sets the thermoset plastics may or may not have to do with the application of heat. In some cases, it is the result of the chemical interactions of the components. Each type of thermoset plastic has its own set of unique properties.Learn more about Thermodynamics
Melting point is the temperature at which a solid melts to become a liquid. Since water is already a liquid, it does not have a point at which it liquefies. Frozen water is called ice and has a normal melting point of zero degrees Celsius, according to Purdue.Full Answer >
Energy consumption refers to the amount of energy consumed by an individual or organization, or to the process or system of such consumption. Nearly every modern convenience increases the amount of energy consumed.Full Answer >
A temperature sensor is a data gathering tool that measures the temperature in the surrounding area and converts the information for use by an observer or additional devices. Temperature sensors have a variety of applications from home use to specific scientific uses.Full Answer >
Conduction works by transferring heat from one molecule to another through a substance. This occurs due to the readiness of the substance to allow molecules to move. A heated molecule moves and shakes rapidly, and some of its heat energy is passed to molecules around it.Full Answer >
