What are plastics PPT?
Plastic is a synthetic material made from a wide range of organic polymers such as polyethylene, PVC, nylon, etc., that can be moulded into shape while soft, and then set into a rigid or slightly elastic form.
What are the 2 main types of plastic?
Thermoplastic and thermosetting
As mentioned above, polymers that are classified as plastics can be divided into two major categories: thermoplastics and thermosets.

Which plastic is best?
3 types of plastic that are considered as safer options among the others are Polyethylene Terephthalate (PET), High-Density Polyethylene (2-HDPE), and Polypropylene (5-PP).
What are plastic materials?
Plastic materials are highly formable materials that are artificially made from organic compounds called polymers, along with additive components. Aside from formability, plastics are generally known to be lightweight, flexible, durable, corrosion-resistant, and cost-effective.
What are different plastics used for?
A. Thermoplastics:
| Types of Plastic | Applications |
|---|---|
| LDPE | Film, bags, toys, coatings, containers, pipes, cable insulation. |
| HDPE | Containers, toys, house wares, industrial wrapping and film, gas pipes. |
| Acrylonitrile-Butadiene-Styrene(SAN/ABS) | Transparent all-weather sheet, electrical insulators, domestic appliances |

Which of the Seven 7 common plastic materials was the most flexible?
Polypropylene (PP)
Its widespread use and popularity are undoubted because polypropylene is one of the most flexible thermoplastics on the planet. Although PP is stronger than PE, it still retains flexibility.
What are the 10 uses of plastics?
Plastics are used to make bicycle helmets, child safety seats and airbags in automobiles. They’re in the cell phones, televisions, computers and other electronic equipment that makes modern life possible. They’re in the roofs, walls, flooring and insulation that make homes and buildings energy efficient.
What type of plastic is 100% recyclable?
Polyethylene terephthalate
Polyethylene terephthalate, also called PET, is the name of a type of clear, strong, lightweight and 100% recyclable plastic. Unlike other types of plastic, PET plastic is not single-use — it is 100% recyclable, versatile, and made to be remade.
What is plastic and its types?
Commodity plastics
| Polymer | Production (Mt) | Polymer type |
|---|---|---|
| polypropylene (PP) | 68 | Polyolefin |
| Polystyrene (PS) | 25 | Unsaturated polyolefin |
| Polyvinyl chloride (PVC) | 38 | Halogenated |
| Polyethylene terephthalate (PET) | 33 | Condensation |
What number is good plastic?
To make a long story short: plastic recycling numbers 2, 4 and 5 are the safest. Whereas plastic numbers 1, 3, 6 and 7 must be avoided. But it does not indicate that you can fearlessly use safer plastic. All plastic products can leach toxic chemicals when heated or damaged.
What plastic is not recyclable?
Well-known non-recyclable plastics include cling film, blister packaging, plastic-coated wrapping paper, composite plastic, bioplastics, and polycarbonate. Thermoset plastics contain polymers that form irreversible chemical bonds and cannot be recycled.
What number is PP?
5
Plastic Number 5 – PP (Polypropylene)
Polypropylene, or PP, is durable and lightweight. Polypropylene is safe to be reused. Polypropylene has a high melting point which makes it a popular choice for hot liquids.
Is PVC can be recycled?
Can plastic PVC packaging be recycled? This type of plastic is not recyclable and should be placed in the waste bin.
What plastic is biodegradable?
According to Bioplastics Guide, there are a few new fossil fuel plastics that can also be biodegradable. The most common ones are Polybutylene succinate (PBS), Polycaprolactone (PCL), Polybutyrate adipate terephthalate (PBAT) and Polyvinyl alcohol (PVOH/PVA).
How many types of plastic are there?
To summarize, there are 7 types of plastic exist in our current modern days: 1 – Polyethylene Terephthalate Plastic Type (PET or PETE or Polyester) 2 – High-Density Polyethylene Plastic Type (HDPE) 3 – Polyvinyl Chloride Plastic Type (PVC)
What plastics are reusable?
Safe Reusable Bottles Do Exist
Safer choices include bottles crafted from HDPE (plastic #2), low-density polyethylene (LDPE, or plastic #4), or polypropylene (PP, or plastic #5).
Who invented plastic?
marketeer Leo Baekeland
Belgian chemist and clever marketeer Leo Baekeland pioneered the first fully synthetic plastic in 1907. He beat his Scottish rival, James Swinburne, to the patent office by one day. His invention, which he would christen Bakelite, combined two chemicals, formaldehyde and phenol, under heat and pressure.
