Plastic

Properties of Plastic

Plastic is a synthetic material made from polymers, which are long chains of molecules. It is a versatile material that is used in a wide variety of products due to its durability, flexibility, and low cost.

Properties of Plastic

• Durability
• Flexibility
• Lightweight
• Waterproof
• Insulation

Types of Plastic

There are several different types of plastic, each with its own unique properties and uses:

1. Polyethylene (PE)
2. Polypropylene (PP)
3. Polyvinyl Chloride (PVC)
4. Polystyrene (PS)
5. Polyethylene Terephthalate (PET)

Environmental Impact

While plastic has many benefits, its disposal and environmental impact have become significant concerns. Plastic waste can take hundreds of years to decompose, leading to pollution of land and water. Efforts are being made to reduce plastic use, increase recycling, and develop biodegradable alternatives.
