Quality index Prime grade First grade Appearance white powdery crystal Solid content (%) ≥99.0 ≥98.0 Melting range (℃) 170.0-174.0 169.0-173.0 Volatile matter (%) ≤0.5 Iron (%) ≤0.001 Application technique ATSC is suit for suspension PVC production, and can also used in other areas. It is a kind of terminator widely adopted when producing PVC. It has the advantage of high terminating speed, high oxidation resistance, low comprehensive cost, good terminating effect, easy storage and so on. Thermal stability will be greatly heightened if used ATSC together with bisphenol A. ATSC is pure solid material, so please dissolve it in alkaline aqueous solution before uses. Suggested dosage: when the polymerization gets to the end (Transformation ratio: about 85%, pressure: 0.1—0.15MPa), terminator ATSC dosage is 0.0033% of the quantity of VCM usually. (Abnormal dosage is adopted to terminate polymerization in emergency, reference dosage is 0.021 % of the VCM.)
