  • Chemical Structure Of Acrylonitrile Butadiene Styrene

    923 Words  | 4 Pages

    Chemical structure Acrylonitrile butadiene styrene (chemical formula (C8H8)x·(C4H6)y·(C3H3N)z) is a graft copolymer synthetised from polymerisation of three monomers, acrylonitrile, 1,3-butadiene and styrene which are shown in Figure 1, and the side chains of ABS plastic are structurally distinct from the main chain. Carbon, nitrogen and hydrogen are the main atoms present in ABS polymers with carbon being the predominant atom. It is a thermoplastic polymer that becomes more pliable when heated and

  • Design Of Experiment : Qualitative Effect Of Prep Shape And Viscosity On Compression Molding Processing

    949 Words  | 4 Pages

    examination performed by HEXPOL Analytical lab, there were small white particulates found within the provided compound. This dispersion issue, after being identified as a styrene resin, was quickly solved by tweaking the provided recipe; there were a few parts of SBR (Styrene-Butadiene Rubber), the most probable source of the undispersed styrene, which was removed and replaced with more carbon black. This did not affect physical properties of the compound. GASKET-O wished to minimize scrap material and therefore

  • The Disastrous Effects of Human Invention Essay

    1494 Words  | 6 Pages

    the 1950s Dow Chemical Company scientist, Ray McIntire invented the material that changed the world of plastics, the material we all know a Styrofoam, Ray McIntire invented Styrofoam from the then common material polystyrene by, “Combining styrene with isobutylene, a volatile liquid, under pressure. The result was foam polystyrene with bubble, 30 times lighter than regular polystyrene” ( Bellis 2).This material quickly caught on as an insulator. Also this new interest in Styrofoam lead

  • The Use Of Creating Polylactic Acid Using Starch From Corn Acid

    1210 Words  | 5 Pages

    Biopolymers are polymers (large molecules, consisting of many repeated subunits) produced by living organisms also known as organic polymers. An example of this is starch, which by chance is one of the most commonly used raw materials in creating Polylactic acid. DNA and RNA are both examples of Biopolymers that have been constructed from nucleotides. Polylactic Acid Polylactic acid is a biodegradable thermoplastic deprived from renewable sources such as cornstarch and sugarcane There are several

  • Harmful Effects Of Recycling In Landfills

    720 Words  | 3 Pages

    2017). Landfills are quickly being filled and very soon there will not be enough space in the world to place trash. extruded polystyrene foam is a material that decomposes over a long period. Inside extruded polystyrene foam is a chemical called Styrene which leaches into substances leading to water pollution when it precipitates and the runoff goes into nearby bodies of water (Little 2017). When something leaches it is being percolated into another liquid or substance. 34 million tons of plastic

  • Mobile Phones Is The Identity Of A User Essay

    2154 Words  | 9 Pages

    EXISTING PRODUCT Since the origin of Mobile phones, the only thing that has not developed much in mobile phones is the SIM card i.e. Subscriber Identity Module Card. It is a device which has user identity, network authorization data, personal security keys, contact lists and text messages. Functionality of the SIM card: • Identification of a User: The International Mobile Subscriber Identity programmed on the SIM card, is the identity of a user, which is linked to a mobile number. • Authentication

  • Plastic Pollution

    1146 Words  | 5 Pages

    What is Plastic Pollution? Plastics are synthetic materials that are made from synthetic resins or organic polymers. Examples of these polymers include nylon, PVC, and polyethylene. Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, and humans. The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans. However, it is slow to
