What is Plastic?
Plastic is a synthetic material made from polymers, which are long chains of molecules. These polymers are derived from petrochemicals and are molded or shaped into various forms to create a wide range of products.
Types of Plastic
There are several types of plastics, including:
- Polyethylene (PE)
- Polypropylene (PP)
- Polyvinyl chloride (PVC)
- Polyethylene terephthalate (PET)
- Polystyrene (PS)
- Polyurethane (PU)
Properties of Plastic
Plastic exhibits various properties such as:
- Flexibility
- Durability
- Lightweight
- Resistance to chemicals
- Insulation
- Transparency (in some types)
Uses of Plastic
Plastic is used in a wide range of applications, including:
- Packaging materials
- Construction materials
- Consumer goods (e.g., toys, household items)
- Medical devices
- Automotive parts
- Electronics
Environmental Impact
While plastic offers many benefits, its disposal and accumulation in the environment have raised concerns due to its non-biodegradable nature. Plastic pollution poses a significant threat to ecosystems and wildlife.
