Cause:
Layers of resin (some of which were chemically changed and is no longer transparent) coat the screw, nozzle, and mold – causing the clouding effect in the product, which may also lead to burning and black spots.
Solution:
- Using RAMCLEAN® 206 for transparent PC based products
- Using RAMCLEAN ® 901 for transparent PMMA products.
Both purging agents does not contain foam and does not require settling. During the settling, RAMCLEAN will cling to the equipment’s polymer layers and pulls them out with it.
