In addition polymerisation, the molecules of the same monomer add together on a large scale to form a polymer. Branched-chain Polymers. Polyethylene plastic is an inexpensive plastic material that is chemically resistant and can be very durable. Thermosets which are formed by ha heat process but are then set (like concrete) and cannot change shape by reheating. Plasticized PVC (or flexible PVC) finds applications in automotive interior trim, cables, PVC … Household items made from polymers include : High Density Polyethylene, HDPE : bottle caps, folding tables and chairs, food storage containers, plastic bags, water pipes for domestic water supply. But, there are more types like CPVC, PVC-O and PVC-M. Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm 3): Flexible PVC is formed by the addition of compatible plasticizers to PVC which lower the crystallinity. D. Acrylic, Silk, Wool. The two most common types of polyethylene compounds are high density polyethylene (HDPE) and low density polyethylene (LDPE). poly-vinyl chloride is largely used for making pipes and electric cables is an example of a linear polymer. Polythene and PVC are examples of:- a. Biodegradable substances b. Thermosetting plastics c. Thermoplastics d. Rayon 2 See answers roja17 roja17 Answer: thermoplastic because their shapes can be changed by melting in the factory. Polymer means many monomers. Bakelite, PVC, polyethylene. For example, Low-density polythene. In turn, PVC is used in a wide range of products. Otherwise the two are essentially the same. Polyvinyl Chloride (PVC, and CPVC) – Polyvinyl chloride is the oldest of the corrosion resistant plastics. Classification: Classification Based on Source: [1] Natural Polymers: These polymers are found in plants and animals. When linear chains of a polymer form branches, then, such polymers are categorized as branched chain polymers. A plastic bag made with polyethylene. PVC, Polythene, Bakelite. By adding a chlorine molecule, CPVC achieves a higher temperature resistance than PVC. Match the column with types of polymer in list I with their examples in list II. Examples include: Unplasticized PVC (or rigid PVC) is used in applications such as pipes, siding, and window profiles. Good examples are melamine (kitchen worktops), Bakelite (black saucepan handles), polyester and … Terylene or Polyethylene terephthalate or polyester is … Answer. Polyvinyl chloride (PVC) Transparent: The color is yellowish translucent and shiny. PVC, i.e. Cross-linked Polymers gojetanishq gojetanishq Answer: Thermoplastics. Features: Transparency is better than polyethylene, polyphenylene, and worse than polystyrene. It is divided into soft and hard polyvinyl chloride according to the amount of additives. Polyvinyl Chloride is widely available in two broad categories: Flexible and Rigid. Both PVC and CPVC materials are approximately 35% - 40% heavier and more rigid than polyolefins. Polyethylene plastic comes in a low density form and a high density form. Good examples are acrylic, polypropylene, polystyrene, polythene and PVC. Both compounds have … Polyethylene (PE) Key applications Typical Properties Suppliers Brands : Polyethylene is a lightweight, durable thermoplastic with variable crystalline structure. Answer. The low density form was discovered first, followed a few years later by the high density form. It is one of the most widely produced plastics in the world (tens of millions of tons are produced worldwide each year). Nylon was the first commercially successful synthetic thermoplastic polymer.
