Study Notes
Introduction to Polymers: Thermoplastics and Thermosetting Plastics
- Polymers are another term for plastics.
- Polymers can be classified into two families: thermoplastics and thermosetting plastics.
- Thermoplastics can be easily formed, recycled, and remolded, but they do not resist heat well.
- Thermosetting plastics can resist heat and fire, making them suitable for electrical fittings and panhandles.
- Thermoplastics are identified by different symbols and numbers for recycling purposes.
- Examples of thermoplastics include acetate, acrylic, LDPE, HDPE, and PET.
- Thermosetting plastics undergo a chemical change when heated and become hard and rigid.
- Examples of thermosetting plastics include epoxy resin, urea formaldehyde, melamine formaldehyde, and glass reinforced plastic (GRP).
- Visual imagery can be used to help remember the different types of plastics and polymers.
- Polypropylene is a tough and flexible thermoplastic that can be visualized with a picture of a school chair and a person doing flexible yoga or gymnastics.
- Understanding the different types of plastics and polymers is important for their appropriate use in various applications.
- A test can be used to assess the knowledge and understanding of the different types of plastics and polymers.
