With the advent of new PP blends, composites or additives to meet the demand for lightweighting or other end use, it is a renewed challenge for most in the PP industry to better balance stiffness, strength, clarity, and reduce cycle times. Often this calls for revisiting your nucleating agents & clarifiers selection strategies...
1. Better select nucleants/clarifiers (phosphate esters, sorbitols, metal salts of fatty acids) for your application by understanding their effect on PP crystallization rate and further on key properties
2. Troubleshoot faster shrinkage, unwanted odor, warpage… by knowing their root causes & best solving strategies (alpha, beta nucleation)
3. Reduce Cycle Times by optimizing your processing conditions (temp., pressure...) for best nucleant performance
