(1 Point) Melamine Polythene PVC Nylon 2 See answers ruchikasinghsaini ruchikasinghsaini Answer: thermosetting plastic is melamine option (a) as thermosetting plastics are the plastics which cannot be melted. A good example of a thermosetting polymer is vulcanized rubber. Answer: d Explaination: (d) LDP is used for making squeeze bottles, flexible hose pipe. The energy may be in the form of heat (generally above 200 degrees Celsius), through a chemical reaction (two-part epoxy, for example), Thermoplastics represent appx 90% by weight of all plastics consumed world-wide. The presence of crosslinks hardens the overall structure. It is used as adhesives as well as in semiconductors and integrated circuits. A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. The use of plastics can be reduced by using bags made of—jute—-or—paper—- instead of polythene … Thermoplastics provide strong, durable adhesion at normal temperatures, and they can be softened for application by heating without undergoing degradation. 3.– rubber — is used in conveyor belts. A TPU can be processed using common techniques, such as injection molding, extrusion, blow molding etc. False. 12.Which is a thermosetting plastic? Other articles where Thermosetting plastic is discussed: adhesive: Synthetic adhesives: …into two general categories—thermoplastics and thermosets. C. PVC. In this lesson, we will learn about the difference between thermosoftening and thermosetting polymers. B. dxb3988616 dxb3988616 Answer: High-density polyethylene is composed of A) primarily linear, unbranched chains of polyethylene in a close packing arrangement. D. Nylon. Nylon is a thermosetting plastic. It is a runny liquid that can be processed to make latex gloves, erasers, and party balloons. MEDIUM. THERMOSETTING PLASTICS 5 Polyester resins. While plastics may be made from just about any organic polymer, most industrial plastic is made from petrochemicals. Known as Glass Reinforced Plastic (GRP) and is used in car body repairs, sailing boats and corrugated sheet, because of its lightness, toughness and resistance to water. A thermosetting resin is a petrochemical material that irreversibly cures. Polyethylene – Polyethylene is a very common thermoplastic, and is often used to create plastic grocery bags or single-use plastic products like shampoo or water bottles. In other words, while other elements might be present, plastics always include carbon and hydrogen. Answer/Explanation. The plastics family generally include materials with a wide range of chemical compositions, including variations of carbon and hydrogen molecules. At room temperature, they are available in the form as liquids. Initially, the polymer is a liquid or soft solid. Fishing nets are made from—nylon—. Polyethylene; Poly Vinyl Chloride(PVC) Teflon; 3.2. Examples of plastics consists of polyethylene, PVC, nylon and ABS. Environmental Durability – Thermosetting plastic elastomers remain stable at very high temperatures and resist harsh environments, and will keep their shape and colors, no matter the exposure to water or atmospheric gases. (a) Melamine (b) Polythene (c) PVC (d) Nylon. Thermoforming polymer Properties ... High density polythene (HDPE) Stiff, strong but lightweight, good plasticity when heated with excellent chemical resistance ... Thermosetting. Such a material is known as thermosetting plastic or thermostats. Polythene. Rubber tapped from para rubber trees is a polymer of isoprene monomers. The cure may be brought on by heat, generally above 392°F (200°C), chemical reaction or suitable irradiation. The polymer which is used in manufacture of squeeze bottles is (a) Polystyrene (b) Teflon (c) Polypropene (d) Low density polythene. True. Thermoset plastics contain polymers that cross-link together during the curing process to form an irreversible chemical bond. Melamine resin or melamine formaldehyde (also shortened to melamine) is a hard, thermosetting plastic material made from melamine and formaldehyde by polymerization. A. However, there is a need for more elastomers that perform at … Acrylic – Acrylic is commonly used for consumer goods.
