TSR CV 60 Latex Grade Natural Rubber
Derived from high-grade field latex, Technically Specified Rubber CV 60 (TSR CV 60) is produced through a careful and controlled process. This process ensures that the viscosity of the rubber is stabilized within a narrow, predefined range. As a result, TSR CV 60 exhibits a softer consistency when compared to traditional rubber grades. The production process is designed to maintain the integrity of the rubber’s properties, ensuring that it meets specific technical specifications.
International ISO standards serve as the benchmark for consistency in quality across global markets. Rubber-producing nations have aligned their standards accordingly; Thailand with STR, Indonesia with SIR, and Malaysia with SMR.
Features of TSR CV 60:
- Dimensional Stability: TSR CV 60 exhibits minimized mill shrinkage as an inherent property, ensuring the maintenance of precise dimensions and form integrity throughout the manufacturing process.
- Enhanced Green Strength: This rubber grade displays increased inherent strength prior to curing, facilitating improved handling and processing capabilities.
- Cost-Effective Production: The elimination of the premastication process and a reduction in reject rates contribute to a more efficient production cycle, resulting in cost savings.
- Resilience to Scorching: TSR CV 60’s non-scorch characteristics allow for higher curing temperatures without an increased risk of defects, promoting a quicker and more efficient production process.
Applications of TSR CV 60:
- Automotive Components:: TSR CV 60 is applicable for the fabrication of various automotive parts, ensuring durability and steady performance over time.
- Industrial Applications: Due to its resilient and robust nature, TSR CV 60 is a fitting material for industrial rolls, covers for conveyor belts, and other rigorous industrial uses.
- Diverse Rubber Goods Manufacturing: TSR CV 60’s adaptable qualities make it appropriate for producing a wide range of rubber products, including but not limited to windshield wiper blades and components bonded with rubber and metal.
- Extrusion and Protective Linings: With its uniform texture and minimized shrinkage during milling, TSR CV 60 stands out as a preferable choice for extruded items.
To understand the differences and find possible latex grade alternatives, one might consider examining other grades like TSR CV 50 and TSR L.
