The Role of SP-60 Internal and External Lubricants in PVC Floor Processing

Introduction

Lubricants are essential additives in PVC flooring production, ensuring smooth processing and consistent product quality. Among them, SP-60 is a widely used internal and external lubricant that plays a dual role in improving both processing performance and end-product appearance.

What is SP-60?

SP-60 is a composite lubricant designed for PVC formulations. It functions as both an internal lubricant—reducing resin intermolecular friction and improving melt flow—and an external lubricant—decreasing adhesion between molten PVC and processing equipment.

The Role of SP-60 in PVC Floor Processing

• Improves Fusion and Flow: Enhances resin processability and ensures uniform melt.

• Reduces Equipment Friction: Minimizes sticking, extending the life of extruders and calendering machines.

• Enhances Surface Quality: Produces smooth, glossy finishes with fewer defects.

• Stabilizes Production: Maintains consistent output and reduces downtime caused by processing issues.

Conclusion

SP-60 is a versatile lubricant for PVC floor processing. By working as both an internal and external lubricant, it provides manufacturers with smoother production, improved surface finish, and higher efficiency.
