YSPVC25-V0 is a high-performance, eco-friendly, antimony-free flame retardant synergist designed specifically for flexible PVC applications. Based on advanced B-P synergy technology, it is engineered to fully replace Antimony Trioxide in PVC formulations.
It acts as a robust char-forming agent and smoke suppressant, forming a ceramic-like protective layer during combustion. Unlike traditional Antimony systems, YSPVC25-V0 significantly improves the mechanical toughness (elongation) of the final product while reducing density.
Key Features & Advantages
-
Excellent Flame Retardancy: Achieves UL94 V-0 (1.6mm) in highly plasticized PVC (50 phr DOP).
-
Superior Mechanical Properties: Dramatically improves Elongation at Break (+36%) compared to Antimony Trioxide systems, offering better flexibility and crack resistance.
-
Cost-Saving Density: Lower specific gravity compared to Antimony systems, increasing volume yield (more meters of cable per ton).
-
Eco-Friendly: Free from Antimony and heavy metals; low smoke generation during combustion.
-
Drop-in Solution: Maintains the same Hardness (Shore A) as traditional formulations; no need to adjust plasticizer dosage.
Applications
-
Wire & Cable: Sheathing and insulation materials requiring high flexibility.
-
Conveyor Belts: Flame retardant rubber/PVC belts.
-
Flexible Films/Sheets: Tarpaulins, artificial leather, and interior automotive trim.
Recommended Dosage
To replace Antimony Trioxide, the recommended starting dosage is 5 – 8 phr in standard flexible PVC formulations containing ATH/MDH fillers.
Packaging & Storage
-
Packaging: 25 kg/bag, paper-plastic compound bag with PE liner.
-
Storage: Store in a cool, dry, and well-ventilated area. Keep container closed when not in use.
