One of the reasons is the overload of non-biodegradable objects like plastics, cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways.

But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam, and this is to make glue out of it. This glue can help reduce the number of Styrofoam that will be thrown away.

Due to the unraveling of polystyrene, the Styrofoam will become a thick like gel. When it is a gel, it will be moldable and when it dries it will be very sticky. It is a very effective adhesive to glue things together.

But it is not very safe since it is napalm and it can damage the lungs if it is burned. It also gives off a foul odor. Statement of the problem 1. Will it help solve the problem of pollution in our society? Will it be useful and effective? What will be the effects of using the glue?

Hypothesis It will not be effective and it will be harmful. Theoretical Framework Theory of Plastic Deformation There are several mathematical descriptions of plasticity. One is deformation theory see e. Although this description is accurate when a small part of matter is subjected to increasing loading such as strain loadingthis theory cannot account for irreversibility.

Ductile materials can sustain large plastic deformations without fracture.

However, even ductile metals will fracture when the strain becomes large enough — this is as a result of work hardening of the material, which causes it to become brittle. Heat treatment such as annealing can restore the ductility of a worked piece, so that shaping can continue.

Scope and Limitations of the Study Styro-glue This aims to gather all 3rd year high school students produces a research that is reliable and precise. The investigation is limited only for the study.

Assumptions This study will be able to inform the public that: Polystyrene — is a synthetic aromatic polymer made from the monomer styrene, a liquid petrochemical.

Styrofoam — a type closed-cell extruded polystyrene foam. Chapter 2 Review of Related Literature and Studies Polystyrene is an aromatic polymer made from the monomer styrene, a liquid hydrocarbon that is manufactured from petroleum by the chemical industry.

Polystyrene is one of the most widely used plastics, the scale being several billion kilograms per year. Pure solid polystyrene is a colorless, hard plastic with limited flexibility.

It can be cast into molds with fine detail. Polystyrene can be transparent or can be made to take on various colors Natta and Corradini, In chemical terms, polystyrene is a long chain hydrocarbon wherein alternating carbon centers are attached to phenyl groups, a name given to the aromatic ring benzene.

Since the molecules are long hydrocarbon chains that consist of thousands of atoms, the total attractive force between the molecules is large.

When heated or, equivalently, deformed at a rapid rate, due to a combination of viscoelastic and thermal insulation properties, the chains are able to take on a higher degree of conformation and slide past each other. This intermolecular weakness versus the high intramolecular strength due to the hydrocarbon backbone confers flexibility and elasticity.

The ability of the system to be readily deformed above its glass transition temperature allows polystyrene and thermoplastic polymers in general to be readily softened and molded upon heating Maul et al. Because of its inherent lightweight characteristic, Styrofoam has found many household and industrial applications.

Companies produce Styrofoam building materials, including insulated sheathing and pipe insulation. Styrofoam insulation has been used in many notable buildings and facilities in North America.

They also produce Styrofoam as a structural material for use by florists and in craft products. Dow insulation Styrofoam has a distinctive blue color; Styrofoam for craft applications is available in white and green. Styrofoam can be used under roads and other structures to prevent soil disturbances due to freezing and thawing The Dow Chemical Company, Just like other issues directly linked to the by-products of petroleum, polystyrene also raised environmental concerns about its disposal.

Discarded polystyrene does not biodegrade for hundreds of years and is resistant to photolysis Bandyopadhyay and Basak, These classic glue sticks are great for easy, no mess gluing.

Perfect for adding dimension to your cards and projects. Cut small pieces of this double sided foam mounting tape to use on the back of die-cuts to pop them up, or use longer strips to cover your card panel to add dimension to the entire card!

Feasibility of food self reliance. Jesus Martinez. If I can accomplish one thing in this essay, it is to smash that myth.

When writing a chemistry essay, everybody should remember that the given science studies substances, their structure, and transformations. In a broad sense, a substance is a kind of matter, which possesses its own mass; for example, it can be elementary particles.
