@All.
The reason why thermoplastic materials cannot be produced by the extrusion process:
The extrusion process requires the plastic material to be continuously melted and forced through a die to form a fixed cross-sectional shape.
- However, thermoplastic materials have a higher melt viscosity compared to other types of plastics, such as thermosetting materials.
- This high melt viscosity makes it difficult for thermoplastic materials to flow through the die and maintain a consistent shape during the extrusion process.
- As a result, the extrusion process is not suitable for producing thermoplastic materials, as it would result in poor shape control and inconsistent product quality.
Therefore, the correct answer is option 'B' - thermoplastic materials cannot be produced by the extrusion process.
