PVC External Lubricant G-74

Superior external lubrication with no compromise on clarity or melt strength for rigid and flexible PVC applications

Imagine crafting flawless, transparent PVC products — whether it’s sleek sheets, flexible films, or precision pellets — without worrying about sticking, uneven flow, or compromised clarity. That’s exactly what PVC External Lubricant G-74 delivers. Developed by Shandong Polymer Additives Co., Ltd., this white flake solid lubricant is engineered to provide superior release properties during processing, ensuring smooth mold release and consistent surface finish. What sets G-74 apart? It enhances the flow of molten PVC without sacrificing transparency — a critical feature for applications where visual quality matters, like packaging films or decorative panels. Its compatibility with metal salt stabilizers makes it a reliable choice for formulators looking to streamline their formulations without compromising stability or performance.

Beyond its core function as a release agent, G-74 offers multiple benefits that elevate your manufacturing process. It improves melt flow ability, reducing energy consumption and equipment wear by allowing material to move more freely through extruders and molds. Importantly, it doesn’t lower melt strength — meaning your final products retain structural integrity and durability. Whether you’re producing rigid pipes, flexible cables, or calendared films, G-74 helps maintain high-quality output while minimizing downtime and scrap rates. The product’s low volatile content (≤0.20%) and controlled acidity (3.5 ± 1.5%) ensure stable processing conditions, making it ideal for both small-scale operations and large industrial production lines.

Unit testing confirms G-74 meets stringent industry standards: it melts between 50–70°C, has a flash point of 230 ± 10°C (ensuring safe handling), and maintains a density of 0.8–0.9 g/cm³ for easy incorporation into resin blends. Its iodine value (1.50 ± 0.50 gI2/100g) indicates excellent chemical stability under heat, preventing degradation during long extrusion cycles. Designed for versatile use, G-74 excels in PVC pelletizing, sheet extrusion, calendaring, and thermoforming applications. Packaged conveniently in 25kg PP bags with PE liners or 550kg woven bags, it’s ready for global supply chains. With a two-year shelf life when stored in cool, dry environments, G-74 gives you confidence in consistency and reliability — every batch, every time. Trust G-74 to turn your PVC production into a seamless, high-performance operation.
