Webplastic, polymeric material that has the capability of being molded or shaped, usually by the application of heat and pressure. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products. These include … WebThermosetting plastics do not melt when heated. They tend to char and burn when heated, but they are resistant to much higher temperatures than thermosoftening …
WebThermoplastics vs. Thermosetting Plastics. The polymerization process creates the polymers used for making plastics. The fabrication process for thermoplastic and thermoset start outs with the same raw materials, such as ethylene and propylene, made from crude oil. The crude oil contains hydrocarbons, which make up the monomers.
