Manufacturers struggling with production bottlenecks, rough surfaces, dimensional instability, and high energy consumption in rubber extrusion processes may find their solution in a groundbreaking polymer additive. Particularly when producing high-hardness rubber products with low or zero plasticizer formulations, achieving efficient, stable, and high-quality extrusion has remained an industry challenge.
VESTENAMER®, a polyoctenamer (TOR)-based rubber additive and processing aid, offers transformative capabilities for extrusion operations. This innovative material optimizes processing performance by significantly improving rubber compound flow characteristics and controllability.
The additive demonstrates particular effectiveness with low-plasticizer or plasticizer-free formulations, addressing their inherent processing difficulties. By enhancing flow properties, VESTENAMER® ensures extrusion stability and uniformity, resulting in smoother surfaces and superior dimensional accuracy of extruded products.
Manufacturers report double-digit productivity gains when increasing screw speeds while simultaneously reducing specific energy consumption and die melt pressure. This translates to lower production costs and improved equipment utilization.
- Enhanced flow characteristics and process control, even with low-plasticizer formulations
- Improved surface quality and dimensional stability of extruded products
- Potential for double-digit productivity increases, particularly at higher screw speeds
- Reduced energy consumption and pressure requirements
- Increased green strength at room temperature, eliminating need for deep-freeze treatment in hose production
For cable manufacturers, VESTENAMER® serves as an efficient rubber processing aid that reduces mixing energy requirements while maintaining electrical and physical properties. The technology lowers discharge temperatures during mixing and ensures flawless extrudate surfaces without compromising post-vulcanization performance.
In hose production, the VESTENAMER® 8012 variant effectively controls interlayer adhesion and fabric penetration while building sufficient green strength without energy-intensive deep-freeze processes. The material reduces compound viscosity at processing temperatures while increasing hardness at room temperature through its crystalline properties.
For profile manufacturers, the additive stabilizes extruded profiles while enhancing flow characteristics, surface smoothness, and dimensional accuracy. At higher screw speeds, formulations containing VESTENAMER® typically achieve double-digit output increases while reducing specific energy consumption, melt pressure, and extrusion shrinkage - particularly valuable for very hard profiles like clip-type base materials.
The material promotes better dispersion of fillers and additives while reducing compound viscosity at higher loading levels. Its inherent crystalline properties increase green hardness/strength at room temperature, crucial for maintaining profile shape before vulcanization, especially in hose production.
