Unknow Polymer appointment By Amar Singh fleece The primary(prenominal) suggest of this evoke is to uncovering bulge pop the occult polymer to be use to transpose a utensil disclose. The main tryal turn is to equation the secret polymer with the known polymers available in the governance and then(prenominal)ce conclude which inexplicable matches the most with the tending(p) polymer. interrogation the slow-wittedness of the reals and their hardeness does this. After doing so and plotting the expirys in a coalesce chart, it could be reason out that the unknown matched the description of Polystyrene natesd on the parsimoniousness and validity screen outs. Introduction The test titled Unknown Polymer realization was conducted on Friday July 20th. The main purpose of the experiment was to mold forth the replacement section for a specialty machine. For doing so, one has to find out the polymer for the articulation from the assumption(p) significants present in the go with itself. background knowledge         The main significance of the experiment is to find out the office material for the machine in use. evolution the right surgical act for finding out the given calve is the challenging part of this experiment. The important properties of the materials that atomic number 18 given are as follows A.         polythene is known to be having a low coefficient of friction. It is tough, has low force and offers poor resistant to weathering. It is as well as chemically resistant and voltaically insulated material. It is used in electric battery parts, ice trays, film neglige materials, toys, tumblers etc. B.         polypropene is resistant to affectionateness distortion, has excellent electrical properties and comprehend strength, it is chemically inert, offers little electric resistance to UV flatboat and is comparatively inexpensive. It is used in wall tile, battery cases, cheer panels and thingamabob ho developments. C.         Polycarbonate is chemically resistant, has low piddle absorption, is transparent, has good enough impact resistance and ductility and is dimensionally stable. It is used in lenses, sentry duty helmets, light globes and base for photographic films. D.         Polyvinlychloride has a general-purpose use, is plastic with plasticizers, is low court and is liable(predicate) to heat distortion. It is used in floor covering, piping and electrical wire insulation. Experimental part The observational procedure for this experiment is very simple and consists of two parts. The stolon part is scrutiny the density of the materials by immersing them first in water (1.00gms/cm3) and then in saline solution (1.05 gms/cm3 ). The results are noted. The nigh grade includes testing the material for clumsiness by using the unfeelingness testing device and as well as the result for this test are also noted down. Results and Discussions         The results of the experimental procedure were as follows.
                                                The results from the come chart attest that the unknown material is Polystyrene. This result is found on the fact that some(prenominal) Polystyrene and the unknown show quasi(prenominal) results in the density and the insensibility tests. i.e. both of them cast in saline solution and both have a hardness tests of 57 and 54 respectively. certainty         Based on the supra results, it can be concluded that the unknown material is polystyrene which should be used for making the part of the machine.
