SVR CV60 is often preferred for easier processing, while SVR CV70 is more suitable for demanding rubber compounds where higher viscosity is required.<\/p>\n<\/p>\n<p><strong>Q: What are the main applications of SVR CV70?<\/strong><br \/>\nA: <\/p>\n<p>SVR CV70 is commonly used in heavy-duty tire compounds, conveyor belts, extruded rubber profiles, molded industrial rubber parts, anti-vibration components, and technical rubber masterbatch applications where stable viscosity and processing consistency are important.<\/p>\n<\/p>\n<p><strong>Q: How does SVR CV70 help reduce processing variation?<\/strong><br \/>\nA: <\/p>\n<p>As a constant-viscosity natural rubber grade, SVR CV70 helps maintain more predictable Mooney viscosity during storage and processing. This supports more stable mixing behavior, better process control, and reduced batch-to-batch variation in production.<\/p>\n<\/p>\n<p><strong>Q: Can APT Rubber supply SVR CV70 with EUDR and FSC\u00ae support?<\/strong><br \/>\nA: <\/p>\n<p>Yes.
