PROCESSIBILITY AND END-USE PROPERTIES OF POLYPROPYLENE CLARIFIED BY A HIGH EFFICIENCY CLARIFIER

摘要

Since the mid 1980's, clear polypropylene (cPP) hasbeen available, mainly on account of sorbitol-based clarifiers. Recently, a novel, high efficiency clarifier, based on a new chemistry platform, has become commercially available. The weaknesses of the sorbitols, such as low thermal and chemical stabilities, have been overcome while the requirements for a melt sensitive clarifier are maintained. The high efficacy and thermal and chemical stabilities of the high efficiency clarifier provide advantages with regard to melt processibility and end-use properties of cPP.
