Plasticizer Product Profile
Product Description
Triphenyl Phosphate Plasticizer - a solid - is the most commonly used flame retardant for Cellulose Acetate. It is compatible with many vinyl resins, cellulosics and synthetic rubber. In vinyl compounds, however, it should be used in conjunction with a liquid plasticizer to prevent crystallizing and blooming. In Cellulose Acetate films, Triphenyl Phosphate imparts flame resistance, good clarity, excellent water resistance, good flexibility and toughness with no tendency toward tackiness.
Triphenyl Phosphate improves tensile strength in nitrocellulose films, and it imparts other favorable properties similar to its effect in Cellulose Acetate. Synthetic rubbers benefit from Triphenyl Phosphate's fair softening action and a resistance to extraction by gasoline and mineral oils. In some engineering thermoplastics, Triphenyl Phosphate imparts excellent fire retardance and processing with minimal loss of strength.
