Types of Plastics
There are several types of plastics, including:
- Polyethylene (PE)
- Polypropylene (PP)
- Polyvinyl Chloride (PVC)
- Polyethylene Terephthalate (PET)
- Polystyrene (PS)
- Polyurethane (PU)
Properties of Plastics
Plastics have several unique properties, including:
- Flexibility
- Durability
- Lightweight
- Insulation
- Transparency
Uses of Plastics
Plastics are used in a wide range of applications, including:
- Packaging
- Construction
- Automobiles
- Electronics
- Medical devices
Environmental Impact
Plastics have a significant impact on the environment, as they are not easily biodegradable and can persist in the environment for hundreds of years. This has led to concerns about plastic pollution and its effects on ecosystems and wildlife.
