UNIPLEX 512
NEOPENTYL GLYCOL DIBENZOATE
CAS NO. 4196-89-8
Uniplex 512 is a low melting (49° C) waxy solid plasticizer. The product is used predominatedly as
thermoplastic processing aid. These uses include:
· Incorporation in polycarbonate or talc-filled polypropylene to improve injection molding
by cycle-time reduction.
· Incorporation in rigid vinyl compounds as an extrusion aid.
· Incorporation in thermoplastic polyesters (e.g. PBT, PCT, PET) to aid crystal growth
during nucleation.
Uniplex 512 is an effective plasticizer for coatings application, particularly in acrylic-based
coatings where excellent ultraviolet light stability is required.
