General engineering plastics can be defined as a class of plastics that possess excellent mechanical and thermal properties. They are commonly categorized into several types:
| Type | Common Uses | Key Properties |
|---|---|---|
| Polycarbonate (PC) | Safety glasses, automotive parts | High impact strength, clarity |
| Nylons (PA) | Gears, automotive components | Wear resistance, strength |
| Acrylonitrile Butadiene Styrene (ABS) | Toys, consumer electronics | Rigid yet tough, good surface finish |
General engineering plastics exhibit several beneficial properties, making them suitable for demanding applications:

As remarked by environmental expert Lisa Green, the question of sustainability is critical in today's plastic usage:
General engineering plastics can be processed using various techniques, each offering different benefits:
| Processing Method | Description | Advantages |
|---|---|---|
| Injection Molding | Heating plastic until it flows, then injecting into molds. | High efficiency, suitable for complex shapes. |
| Extrusion | Forcing heated material through a die to create long shapes. | Continuous production, good for uniform profiles. |
| Blow Molding | Creating hollow plastic parts by inflating heated plastic. | Cost-effective for large volumes. |
According to market analyst Richard Kent, the demand for general engineering plastics continues to grow:
