5. Use of Recycled Material

Fig. 5-1 shows the change of properties after repeating 100% recyclings. Each property undergo little change. However, attention should be paid to gradual discoloration.

Matters requiring attention during recycling:

• Avoid contamination: Dust and foreign matter may lead to breakage of the molding.
• Eliminate large particles: Problems may occur in plasticization.
• Elimination of powder produced in crushing is recommended: Eccentric deposition of the powder may cause problems in plasticization.
