How do we get plastic?

Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.

Why is plastic harmful?

Plastics are affecting our oceans Ocean-dwelling creatures are being killed by stray plastic floating in the water, as well as by plastic fragments they mistake for actual food. Plastic particles are ingested by marine life, and as we produce more single-use plastics, this problem will only become worse.

What are the properties of thermosetting plastic?

Thermosetting plastics are generally stronger than thermoplastic materials due to the three-dimensional network of bonds (crosslinking), and are also better suited to high-temperature applications up to the decomposition temperature since they keep their shape as strong covalent bonds between polymer chains cannot be …

What are three properties of plastic?

Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.

What are the physical properties of plastic water bottles?

Some of the common physical characteristics of plastic are:transparency.flexibility.elasticity.permeable.water resistant.electrically resistance.Plastic is somewhat reactive to oxygen, over time it degrades as it is reacting to oxygen.generally plastic is soft.More items…

What are the advantages of plastic?

What are the advantages of plastic? The properties of plastic are resistant to rust and chemically inert. They have low coefficient thermal expansion and have strong thermal and electric insulating properties. Plastic benefits are very good water-resistant and have good adhesivity.

Which is an example of thermosetting plastic?

Common examples of thermoset plastics and polymers include epoxy, silicone, polyurethane and phenolic. In addition, some materials such as polyester can occur in both thermoplastic and thermoset versions. … Different thermosets provide different advantages when used as a production material.

What are the 7 types of plastic?

Here are the seven standard classifications for plastics, and the recycling and reuse information for each type.#1 – PET (Polyethylene Terephthalate) … #2 – HDPE (High-Density Polyethylene) … #3 – PVC (Polyvinyl Chloride) … #4 – LDPE (Low-Density Polyethylene) … #5 – PP (Polypropylene) … #6 – PS (Polystyrene)More items…•

What is the chemical properties of plastic?

The term “plastics” includes materials composed of various elements such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur. Plastics typically have high molecular weight, meaning each molecule can have thousands of atoms bound together.

Why do we need plastic?

Plastic is durable and provides protection from contaminants and the elements. … It reduces food waste by preserving food and increasing its shelf life. It protects food against pests, microbes and humidity.

What is plastic used for?

Plastics is versatile, hygenic, lightweight, flexible and highly durable. It accounts for the largest usage of plastics world wide and is used in numerous packaging applications including containers, bottles, drums, trays, boxes, cups and vending packaging, baby products and protection packaging.

What are thermosetting plastics give at least 2 examples?

Examples include polythene, polystyrene. Thermosetting polymers are cross-linked or heavily branched polymers which get hardened during the molding process. These plastics cannot be softened again on heating. Examples of thermosetting plastics include bakelite, urea-formaldehyde resins.
