What are the advantages use of plastic?

Answer 1

; Polypropylene (PP) : Food containers, appliances, car fenders (bumpers). ; Polystyrene (PS) : Packaging foam, food containers, disposable cups, plates, cutlery, CD and cassette boxes. ; High impact polystyrene (HIPS) : Fridge liners, food packaging, vending cups. ; Acrylonitrile butadiene styrene (ABS) : Electronic equipment cases (e.g., Computer Monitors, printers, keyboards), drainage pipe. ; Polyethylene terephthalate (PET) : Carbonated drinks bottles, jars, plastic film, microwavable packaging. ; Polyester (PES) : Fibers, textiles. ; Polyamides (PA) (Nylons) : Fibers, toothbrush bristles, fishing line, under-the-hood car engine mouldings. ; Poly(vinyl chloride) (PVC) : Plumbing pipes and guttering, shower curtains, window frames, flooring. ; Polyurethanes (PU) : Cushioning foams, thermal insulation foams, surface coatings, printing rollers. (Currently 6th or 7th most commonly used plastic material, for instance the most commonly used plastic found in cars). ; Polycarbonate (PC) : Compact discs, eyeglasses, riot shields, security windows, traffic lights, lenses. ; Polyvinylidene chloride (PVDC) (Saran) : Food packaging. ; Polyethylene (PE) : Wide range of inexpensive uses including supermarket bags, plastic bottles. ; Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) : A blend of PC and ABS that creates a stronger plastic. Used in car interior and exterior parts, and mobile phone bodies. ; Polymethyl methacrylate (PMMA) : Contact lenses, glazing (best known in this form by its various trade names around the world; e.g., Perspex, Oroglas, Plexiglas), aglets, fluorescent light diffusers, rear light covers for vehicles. ; Polytetrafluoroethylene (PTFE) (trade name Teflon) : Heat-resistant, low-friction coatings, used in things like non-stick surfaces for frying pans, plumber's tape and water slides. ; Polyetheretherketone (PEEK) (Polyetherketone) : Strong, chemical- and heat-resistant thermoplastic, biocompatibility allows for use in medical implant applications, aerospace mouldings. One of the most expensive commercial polymers. ; Polyetherimide (PEI) (Ultem) : A high temperature, chemically stable polymer that does not crystallize. ; Phenolics (PF) or (phenol formaldehydes) : High modulus, relatively heat resistant, and excellent fire resistant polymer. Used for insulating parts in electrical fixtures, paper laminated products (e.g., Formica), thermally insulation foams. It is a thermosetting plastic, with the familiar trade name Bakelite, that can be moulded by heat and pressure when mixed with a filler-like wood flour or can be cast in its unfilled liquid form or cast as foam (e.g., Oasis). Problems include the probability of mouldings naturally being dark colours (red, green, brown), and as thermoset difficult to recycle. ; Urea-formaldehyde (UF) : One of the aminoplasts and used as a multi-colorable alternative to Phenolics. Used as a wood adhesive (for plywood, chipboard, hardboard) and electrical switch housings. ; Melamine formaldehyde (MF) : One of the aminoplasts, and used as a multi-colorable alternative to phenolics, for instance in mouldings (e.g., break-resistance alternatives to ceramic cups, plates and bowls for children) and the decorated top surface layer of the paper laminates (e.g., Formica). ; Polylactic acid (PLA) : A biodegradable, thermoplastic, found converted into a variety of aliphatic polyesters derived from lactic acid which in turn can be made by fermentation of various agricultural products such as corn starch, once made from dairy products. ; Plastarch material : Biodegradable and heat resistant, thermoplastic composed of modified corn starch.
