Resin Transfer in Laminate Production with Verderflex ROLLIT

Demand for laminated furniture, countertops, and flooring materials is rapidly increasing worldwide. Along with this, the need for abrasion-resistant coatings (ARP - Abrasion Resistant Paper) for hardened surfaces is also rising. Abrasion-resistant papers, especially those applied in VITS coating machines, are a crucial element in enhancing the durability of the final product.

These abrasion-resistant surfaces are typically produced by adding corundum (Al₂O₃) to melamine resin. This results in an improved final product surface that can pass the Martindale scratch test.

The Perfect Solution for Viscous and Abrasive Resins: Verderflex ROLLIT

The combination of melamine resin with abrasive additives such as microcorundum and corundum creates a high-viscosity and abrasive fluid. Due to these properties, peristaltic pump technology is one of the most suitable solutions for this process, where other pump technologies struggle. This is where Verderflex ROLLIT peristaltic pumps come into play.

Peristaltic pumps operate on a remarkably simple yet proven principle:

The pump moves the fluid by alternately compressing and relaxing the hose that carries the fluid.

The rotating cylinders compress the hose completely, preventing fluid from escaping.

Since the hose is the only component in direct contact with the product, there is no need for check valves or additional sealing components as in conventional pumps.

This system enables the safe and efficient transport of abrasive and viscous materials.

Advantages Compared to Other Pump Technologies

Other pump technologies struggle to pump such viscous and abrasive fluids due to diaphragm or stator wear, seal problems, and shear forces. These systems include:

❌ High shear forces can cause bubble formation in the resin, negatively affecting the final product quality.

❌ Viscous materials can adhere to pump components, increasing service times and maintenance costs.

Verderflex ROLLIT peristaltic pumps offer a unique solution that overcomes these challenges. They are successfully used in numerous laminate production facilities worldwide for the reliable transfer of viscous and abrasive resins to coating processes.

Advantages of Verderflex® ROLLIT

  • Oil-Free Operation: Lubrication of the hose is only necessary during installation. It is recommended to renew lubrication after 300 hours of operation.
  • Quick and Easy Hose Replacement: Offers easy maintenance with minimal downtime.
  • Three-cylinder mechanism: Lower vibration – provides a more stable flow, especially in 6-cylinder, double-head pumps.

PTFE-coated cylinders and fittings minimize friction, extending hose life and reducing heat generation.

Verderflex ROLLIT is the ideal solution for the safe, efficient, and low-maintenance transport of resins in laminate production processes.
