- Processing Methods
- Injection Molding
- Drying
Dry the material for a minimum of 4 - 6 hours at 60o C. A moisture content of less than 0.07% (700 ppm) is required / less than 0.10% (1000 ppm) is recommended. Avoid exposing the material to atmospheric conditions after drying; process immediately.
- Markets
- Consumer Goods
- Personal Care
- Storage
Keep the material tightly closed in a dry and cool place. Keep away from heat and sources of ignition and avoid exposure to moisture, dampness. Do not stor outdoors. Use material within 6 month after delivery. \
