PVC WPC Door Special External Lubricant ZB60

Special Instruction:

Product Introduction：

1. Product Overview：
ZB60 is a high-performance external lubricant specifically formulated for PVC extrusion processing. It effectively prevents material adhesion to screws, barrels, and dies, ensuring smooth, stable production with excellent release properties. Its well-balanced lubrication profile, combined with non-precipitating characteristics and a wide processing safety margin, makes it an indispensable additive for manufacturers seeking reliable extrusion performance and superior product quality.

2. Product Principle：
ZB60 functions as a classic external lubricant by forming a thin, uniform lubricating film between the molten PVC and the metal surfaces of processing equipment. This film reduces friction and adhesion, facilitating smooth melt flow and preventing material buildup on screws, barrel walls, and die lips. The low melting point (60–65°C) ensures early melting and rapid film formation, providing immediate release protection from the feed zone onward. Unlike some lubricants that can cause plate-out or precipitation over time, ZB60 maintains excellent compatibility with PVC and other additives, ensuring long-term stability without adverse effects—even at higher addition levels. The extremely low volatilization (≤0.5%) guarantees clean processing with minimal smoke, odor, or die buildup.

3. Performance Characteristics：
ZB60 delivers outstanding lubrication efficiency with a melting point of 60–65°C, ensuring rapid activation and sustained release properties throughout the extrusion process. The ultra-low volatile content (≤0.5%) minimizes fuming and plate-out, enabling longer production runs and cleaner working conditions. The additive exhibits excellent non-precipitating characteristics, maintaining consistent performance without blooming or surface defects. Its wide safety margin means that excess addition will not cause harmful effects, providing formulation flexibility and reducing the risk of processing errors. Furthermore, ZB60 enhances discharge stability, reduces melt pressure, and improves overall melt flow, contributing to smoother extrusion and higher productivity.

4. Usage and Dosage：
Recommended addition level is 0.3–1% based on total PVC formulation weight. For standard rigid PVC profiles and pipes, dosages of 0.4–0.7% typically provide optimal external lubrication without compromising internal lubrication balance. For high-speed extrusion lines or complex profile geometries, dosages toward 0.8–1% may be beneficial. Systematic trials should be conducted to fine-tune the dosage for specific equipment, formulations, and processing conditions, taking care to balance external lubrication with internal lubricants for optimal melt homogeneity.

Product Advantages：

1. Prevents Material Adhesion to Processing Equipment
ZB60 forms an effective release barrier between the PVC melt and metal surfaces, preventing sticking and buildup on screws, barrel walls, and die lips. This reduces cleaning frequency, minimizes downtime, and ensures consistent product quality.

2. Non-Precipitating for Long-Term Stability
Unlike some lubricants that can bloom or precipitate over time, ZB60 maintains excellent compatibility with PVC and other additives. This ensures consistent performance without surface defects, discoloration, or loss of lubrication efficiency.

3. Safe and Forgiving Processing Window
Excess addition of ZB60 will not cause harmful effects, providing manufacturers with a wide processing safety margin. This reduces the risk of formulation errors and enables flexible adjustment to accommodate varying processing conditions.

4. Excellent Discharge Stability and Melt Flow Improvement
ZB60 enhances discharge stability, reduces melt pressure fluctuations, and improves overall melt flow. This enables smoother extrusion, more consistent dimensions, and higher line speeds without quality compromise.

5. Low Volatility for Clean Processing
With volatilization ≤0.5%, ZB60 minimizes fuming, odor, and die plate-out during extended production runs. This improves workplace safety, reduces equipment cleaning, and enhances the surface quality of finished products.

6. Early Activation for Immediate Lubrication
The low melting point (60–65°C) ensures rapid melting and immediate lubricating film formation from the feed zone, providing early protection against adhesion and reducing wear on processing equipment.

7. Versatile Across Multiple Extrusion Applications
ZB60 performs effectively in a wide range of rigid and semi-rigid PVC extrusions, including profiles, pipes, sheets, and fittings, providing formulation flexibility and consistent lubrication performance.

8. Compatible with Various Additive Systems
ZB60 exhibits excellent compatibility with PVC stabilizers, processing aids, impact modifiers, fillers, and other lubricants. This simplifies formulation development and ensures reliable performance across diverse compound formulations.
