High-Sulfur Content Additive for Superior Extreme Pressure
Performance T321
T321 Sulfurized Isobutylene is manufactured using a
precision-controlled process involving isobutylene,
sulfur chloride, and sodium sulfide, with catalytic vulcanization
and dechlorination.
Key features include:
- Extreme Pressure Resistance: High sulfur content (40%-46%) ensures superior wear protection.
- Oil Solubility: Light-colored and fully soluble, it blends seamlessly with base
oils.
- Environmental Compliance: Low chlorine content (≤0.5%) aligns with modern regulatory
standards.
T321’s versatility makes it suitable for gear oils, industrial
lubricants, and formulations requiring phosphorus-nitrogen
additives.
