Plastic is everywhere—in our homes, cars, offices, and even medical instruments. Strong, lightweight, and affordable, it’s one of the most useful materials ever created. But what exactly is plastic made of, and why are there such a bunch of types, such as PP, HDPE, LLDPE, PVC, and EVA? 

Let’s break it down in simple words.

polymers

The science behind plastic

Plastics are made from polymers, which are long chains of smaller units called monomers. These monomers are mainly derived from petroleum and natural gas. Through chemical processes such as polymerisation, these small molecules bond together to form strong, flexible materials – what we call plastics.

There are two main types of polymers:

Thermoplastics: Can be melted and reshaped a bunch of times (for example: PP, HDPE, PVC).

Thermosetting plastics: They cannot be remelted after moulding (for example, epoxy and melamine).

Most plastics used today are thermoplastics because they can be recycled and recycled.

How is plastic made?

Extraction: Crude oil or natural gas is collected.

Refining: Hydrocarbons are separated into smaller molecules such as ethylene and propylene.

Polymerisation: These molecules are converted into polymers.

Pelletisation: The polymer is cooled and cut into plastic granules that are used by manufacturers to make products.

The main types of plastics

polymers

Each type of plastic has unique properties and areas of use.  Here are the most common: Polypropylene (PP)

PP is light, strong, and chemical resistant. It’s used for everything from packaging to furniture.

Applications: Household containers, films, car parts, textiles.

Popular grades:

  • PP RIL H110MA
  • PP CP, CM12
  • B MH13
  • B 100MC

High-Density Polyethylene (HDPE)

HDPE is strong and durable with high impact and chemical resistance. 

Applications: Water pipes, storage tanks, bottles.

Grades: 

  • PE 63
  • PE 80
  • PE 100 (used for industrial pipes and tanks).

Linear Low-Density Polyethylene (LLDPE)

polymers

LLDPE combines strength and flexibility. It’s often used in packaging films and agricultural panels.

Applications: Stretch films, carry bags and linings.

Grades 

  • LLDPE R24A 
  • LLDPE R35A 
  • LLDPE 9018

Polyvinyl Chloride (PVC)

PVC is strong and easy to mould. This is one of the most common types of plastic in the construction industry and the electrical industry.

Applications: pipes, cables and floor coverings.

grades: 

  • PVC S65 
  • PVC S67 
  • suspension and emulsion grades.

Ethylene Vinyl  Acetate (EVA)

EVA is soft and flexible and is often used in products that require cushioning or transparency.

Area of ​​use: shoe soles, wire, foil, solar panels.

Also read: Ethylene Vinyl Acetate (EVA) and its applications: intensive understanding

Why is plastic so useful?

Plastic is very popular because it’s

  • Light and strong
  • It can be easily molded into different shapes
  • Resistant to water and chemicals
  • Recyclable (in most forms of thermoplastics)

These properties make plastics cost-effective and ideal for industrial and consumer use.

The future of plastic in India
