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