What is plastic and its type?
Thermoplastics and thermosetting polymers are the two types of plastic.
The name “plastic” refers to the property of plasticity, the ability to deform without breaking.
The polymer used to make plastic is almost always mixed with additives, including colorants, plasticizers, stabilizers, fillers, and reinforcements..
What are 5 common plastics used in homes?
The 5 Most Common Plastics & Their Everyday Uses Polyethylene Terephthalate (PET) … High Density Polyethylene (HDPE) … Polyvinyl Chloride (PVC) … Low Density Polyethylene (LDPE) … Polypropylene (PP)
Where is plastic used the most?
ChinaWith the largest population, China produced the largest quantity of plastic, at nearly 60 million tonnes. This was followed by the United States at 38 million, Germany at 14.5 million and Brazil at 12 million tonnes.
What was used before plastic?
Before the invention of plastic, the only substances that could be molded were clays (pottery) and glass. Hardened clay and glass were used for storage, but they were heavy and brittle. Some natural substances, like tree gums and rubber, were sticky and moldable.
Why do we use plastic?
Plastic is: … Durable: because plastic packaging is so durable, plastic packaging can be very thin. This means it uses fewer resources and takes up less space for transport which means fewer trucks, trains or planes are needed to transport it. Versatile: plastics can be transformed in many different ways.
What are the main types of plastics?
The seven types of plastic include:Polyethylene Terephthalate (PETE or PET)High-Density Polyethylene (HDPE)Polyvinyl Chloride (PVC)Low-Density Polyethylene (LDPE)Polypropylene (PP)Polystyrene or Styrofoam (PS)More items…•

What 2 main elements are in all plastics?
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.
What is the strongest type of plastic?
PolycarbonatePolycarbonate is the strongest plastic that is 200 times stronger than glass and is warranted against breakage or cracks.
What are the 3 types of plastic?
To summarize, there are 7 types of plastic exist in our current modern days:1 – Polyethylene Terephthalate (PET or PETE or Polyester) … 2 – High-Density Polyethylene (HDPE) … 3 – Polyvinyl Chloride (PVC) … 4 – Low-Density Polyethylene (LDPE) … 5 – Polypropylene (PP) … 6 – Polystyrene (PS) … 7 – Other.
What is plastic explain?
Plastics is the term commonly used to describe a wide range of synthetic or semi-synthetic materials that are used in a huge and growing range of applications. … The raw materials used to produce plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil.
Which plastic is safe?
HDPEHDPE is the most commonly recycled plastic and is considered one of the safest forms of plastic. It is a relatively simple and cost-effective process to recycle HDPE plastic for secondary use. HDPE plastic is very hard-wearing and does not break down under exposure to sunlight or extremes of heating or freezing.
Who invented plastic?
Polyvinyl chloride (PVC) was first polymerised between 1838-1872. A key breakthrough came in 1907, when Belgian-American chemist Leo Baekeland created Bakelite, the first real synthetic, mass-produced plastic.
Why is plastic harmful?
Plastic affects human health. Toxic chemicals leach out of plastic and are found in the blood and tissue of nearly all of us. Exposure to them is linked to cancers, birth defects, impaired immunity, endocrine disruption and other ailments.
How is plastic made step by step?
Plastics are made from raw materials like natural gas, oil or plants, which are refined into ethane and propane. Ethane and propane are then treated with heat in a process called “cracking” which turns them into ethylene and propylene. These materials are combined together to create different polymers.
