Ultimate Clarity Tin Stabilizer
Engineered for ultimate optical clarity in rigid transparent PVC — unmatched haze and yellowness index performance.
VT-977 is Voltiquetech's flagship clarity-grade stabilizer, purpose-built for transparent PVC sheet, rigid film, and high-end packaging where optical performance is non-negotiable. Its ultra-pure synthesis route and proprietary mercaptide ligand structure deliver near-zero haze and the lowest yellowing index in its class, making it the preferred stabilizer for crystal-clear PVC applications.
Key Features
Industry-leading optical clarity — lowest haze index
Minimal yellowing under prolonged heat exposure
Optimized for calendering and extrusion processes
Low volatility — reduced fume and plate-out
Excellent dynamic thermal stability
Compatible with all rigid PVC K-values
