EFFECTIVENESS OF IMPROVISED STYRO-CUTTER Polystyrene (PS) is a synthetic aromatic polymer made from the monomer styrene‚ a liquid petrochemical. (Retrieved: April 12‚ 2013 http://en.wikipedia.org/wiki/Polystyrene) Expanded polystyrene beads makes up a Styrofoam. Styrofoam is used almost everywhere: it is used as housings of appliances such as televisions‚ computers and refrigerators. It is also utilized as drinking cup especially for hot beverages because of its insulating properties. As a student

Introduction Styrofoam is the trademarked name of the plastic foam polystyrene. Polystyrene is not biodegradable and resists compression‚ making it a persistent part of landfill waste. When acetone and polystyrene are combined‚ the polystyrene dissolves. For the investigatory project‚ the student could explore the effectiveness of acetone in reducing polystyrene for recycling. The student could measure how much polystyrene is dissolved by a particular volume of acetone. Experimental Design

and carbon dioxide can cause Global Warming. So the researcher conducted an experiment about Styro. Manufacturers create Styrofoam through the alteration of polystyrene. Polystyrene is composed of a long chain of styrene molecules. In its unaltered form‚ polystyrene is rigid and translucent. A blowing agent transforms molten polystyrene into Styrofoam through the construction of a porous cellular structure. The organic compound (CH3)2CO‚ or acetone‚ is a translucent flammable liquid that exhibits

Question: Can we recycle polystyrene in a cost efficient way? If so‚ what impact does this have on the environment? Purpose: The purpose of this experiment is to see if we can recycle polystyrene using acetone. If this is possible‚ this can be used to help improve our environment since polystyrene itself is not biodegradable. Hypothesis: I hypothesis that polystyrene‚ mainly known as styrofoam‚ can be recycled using acetone. This cost efficient and easy method will not only motivate both individuals

Plastic Composition and Types of Plastic A plastic is made up principally of a binder together with plasticizers‚ fillers‚ pigments‚ and other additives. The binder gives a plastic its main characteristics and usually its name. Thus‚ polyvinyl chloride is both the name of a binder and the name of a plastic into which it is made. Binders may be natural materials‚ e.g.‚ cellulose derivatives‚ casein‚ or milk protein‚ but are more commonly synthetic resins. In either case‚ the binder materials consist
