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 predominately 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.
