Molding conditions
- Pre-drying: 100°C x 6hr, for 8007, which does not usually need drying, perform pre-drying at 60°C for 24 hours if stringent optical characteristics are required.
- The melt temperature varies for each grade, so please refer to the Grade Molding Condition Sheet for the specific conditions applicable to that grade.
