Answer to Question 1

If the viscosity of the melted resin were too high, the melt may not flow without external pressure and, therefore, would not work well as a hot-melt casting resin. Another problem could arise if the resin degraded easily at the temperatures required to keep the material liquid.

Answer to Question 2

Sheets made by cell casting are better optically than continuous cast sheets. The cell cast sheets also have better dimensional control and give more uniform shrinkage when heated. The advantage to continuous casting is that the production rate is much higher than with cell casting.
