Plastic Definition
Plastic refers to a synthetic or processed substance, usually an organic material made from polymers. These polymers are often thermoplastic or thermosetting, meaning they can be reshaped when heated or undergo a chemical change to form a solid structure.
Key Characteristics
- Plastics are primarily organic polymers.
- They can be thermoplastic, which softens when heated and hardens when cooled.
- They can also be thermosetting, which irreversibly hardens during curing processes.
Usage
The term "plastic" broadly covers many materials commonly used in manufacturing and everyday products due to their moldability and durability.
"Plastic" importantly denotes any of numerous synthetic or processed materials exhibiting these polymer-based characteristics.
Plastic materials are versatile and essential in modern industry because of their ability to be reshaped and their lasting strength after forming.
