EVALUATION OF UNIPLEX FRP-45 WITH ANTIMONY TRIOXIDE IN FLEXIBLE PVC APPLICATIONS
Uniplex FRP-45 works well in conjunction with Antimony Trioxide (Sb2O3) (See Tables 7 - 9). This synergy allows attainment of:
Higher oxygen index levels
Lower smoke generation (NBS smoke chamber)
Improved low temperature brittleness
Minimize effect on the PVC resins specific gravity than with Sb2O3 alone

COMPARISON OF FLAME RETARDANT PLASTICIZERS IN FLEXIBLE PVC WIRE AND CABLE APPLICATIONS
Uniplex FRP-45 combines high flame retardancy with plasticization when used in flexible PVC wire and cable compound. Formulations incorporating Uniplex FRP-45 achieve higher oxygen index values than those containing the traditional organophosphates (eg. Kronitex 100 from FMC Corporation and Santicizer 148 from Monsanto). The primary plasticizer (Uniplex 546-A, TOTM) was replaced with flame retardant plasticizers to achieve oxygen index values of 29 and 32.

APPLICATIONS IN EPDM
Uniplex FRP-45 combines high flame retardancy with plasticization when used in Ethylene-Propylene-Diene Monomer (EDPM) formulations. Uniplex FRP-45 can achieve a UL-94 V-O rating at lower loadings than with traditional flame retardant systems. Uniplex FRP-45 offers the following advantages:
High flame retardant efficiency
Good plasticization
High thermal stability
Good compatibility with EPDM
Low smoke values (NBS smoke chamber versus traditional flame retardant systems)
Better (aged and unaged) physical properties
Good UV stability
