Antireversion Agent STD BPF-88
Rubber additives 2025-05-14
Product Overview:
STD BPF-88 is a specialized antireversion agent designed to address sulfur reversion—a common challenge in rubber vulcanization. It optimizes crosslink stability, ensuring rubber compounds maintain mechanical integrity during high-temperature processing or prolonged use.
Key Features:
- Thermal Stability: Prevents degradation of sulfur crosslinks at elevated temperatures, reducing reversion risk.
- Flexible Crosslinking: Forms resilient, heat-resistant networks that adapt to dynamic stresses.
- Compatibility: Suitable for natural rubber (NR), synthetic rubbers (SBR, BR), and blended formulations.
Applications:
- Tire Industry: Enhances tread durability, reduces rolling resistance, and improves adhesion to steel cords.
- Industrial Rubber: Used in shock absorbers, conveyor belts, and track pads for heavy machinery.
Benefits:
- Extended Service Life: Minimizes cracking and fatigue under severe thermal conditions.
- Process Efficiency: Allows safer over-vulcanization without compromising product quality.
- Cost Savings: Reduces material waste and rework by stabilizing crosslink density.
Safety & Handling:
Avoid direct skin/eye contact; use protective gear (gloves, goggles).
Store in cool, dry conditions away from oxidizing agents.
