Enhance PVC Pipe Production with the Right Lubricants: Internal vs. External Explained

 When it comes to manufacturing high-quality PVC pipes, the role of lubricants is often underestimated. However, choosing the right lubricant—internal or external—can significantly impact your production efficiency, pipe surface finish, and long-term product performance.

At Sukhmani Impex, we specialize in supplying high-performance PVC lubricants tailored for the modern plastic processing industry.

Internal vs. External Lubricants: What’s the Difference?

  • Internal Lubricants are used to reduce friction between the PVC molecules, improving melt flow and ease of processing. They help in stabilizing the internal structure without affecting surface properties.

  • External Lubricants work on the interface between the PVC compound and metal surfaces (like dies and barrels), preventing sticking, ensuring smooth release, and enhancing the surface finish of the final pipe.

Why It Matters for Your Business:

  • Better extrusion speed

  • Fewer die marks and surface defects

  • Enhanced dimensional stability

  • Increased tool life and machine protection

  • Cost-effective, consistent production cycles

How Choosing the Best Lubricant for PVC Improves Your Manufacturing Process

Image
  When it comes to manufacturing PVC pipes, sheets, or profiles, selecting the best lubricant for PVC is a crucial decision that directly impacts product quality and production efficiency. A high-quality lubricant not only ensures smooth processing but also extends equipment life and reduces downtime. One lubricant gaining popularity in the industry is Fluid-X. Unlike traditional PVC lubricants that often rely heavily on polyethylene wax (PE wax), Fluid-X offers an optimized formulation tailored for modern PVC manufacturing. What Makes Fluid-X Different? Fluid-X’s formula is designed with a balance of essential ingredients for superior performance: S PVC (K-67): The main polymer base providing strength and flexibility. Calcium Carbonate: A filler that enhances durability and reduces overall production costs. Lead Stabilizer: Ensures thermal stability during high-temperature processing. Stearic Acid and Calcium Stearate: Present in controlled amounts to improve melt flow and dis...
