BRIEF INTRODUCTION:
FR-FS11 is a high-performance flame retardant specifically engineered for use in PVC and SBR (Styrene- Butadiene Rubber) applications. In flexible PVC formulations, 1.0 to 1.25 parts per hundred resin (PHR) of FR-
FS11 can effectively replace 1.0 PHR of Antimony Trioxide (Sb₂O₃), delivering equivalent flame retardancy
without compromising mechanical or electrical properties.
APPLICATIONS
PVC wire & cable compounds
PVC synthetic leather
PVC tarpaulin
SBR-based products
Other formulations utilizing Sb₂O₃ as a flame retardant synergist
At a 1:1 replacement ratio
with Sb₂O₃, FR-FS11 exhibits a slightly lower oxygen index (by 1.2 units), while other properties remain comparable.
When used at 1.2 PHR, FR- FS11 delivers mechanical properties similar to Sb₂O₃, with a slight improvement in volume resistivity.
KEY FEATURES
Superior flame retardant performance
Maintains mechanical and electrical integrity
Excellent cost-effectiveness
