Technically Specified Rubber (TSR) is a form of natural rubber that is graded and packaged according to specific technical parameters, ensuring consistency and quality for industrial applications. Unlike traditional sheet or crepe rubbers, TSR is processed to meet stringent specifications regarding cleanliness, purity, and other properties.
Key Classifications of Technically Specified Rubber
TSR is categorized into various types, each designed to meet specific quality requirements and suitable for different manufacturing processes. These classifications are crucial for identifying the rubber best suited for particular industrial uses, from tire manufacturing to general rubber goods.
The following table outlines the different types of TSR and their key characteristics:
| TSR Type | Key Characteristics |
|---|---|
| TSR CV | Produced from high-quality field latex, this type is characterized by its constant viscosity (CV). This feature ensures consistent processing behavior during manufacturing, making it highly desirable for applications requiring stable rheological properties. |
| TSR L | Also produced from good-quality field latex, TSR L (Latex Grade) is notably distinguished by its light color and exceptional cleanliness. Its high purity makes it ideal for products where aesthetics and minimal contamination are critical. |
| TSR 5 | This is a premium grade of TSR, recognized for having very low impurity levels and excellent consistency. TSR 5 is often preferred for high-performance applications where purity and precise control over material properties are paramount. |
| TSR 10 | A widely used general-purpose grade, TSR 10 offers a good balance of purity and cost-effectiveness. It typically has slightly higher permissible impurities compared to TSR 5, making it versatile for a broad range of industrial uses. |
| TSR 20 | This is a standard and more economical grade of TSR, commonly utilized in various applications where slightly higher levels of impurities are acceptable. TSR 20 is a workhorse in the industry, suitable for products that do not require the absolute highest purity. |
| TSR 10CV | This type combines the characteristics of TSR 10 (a general-purpose grade) with the added benefit of constant viscosity (CV). The CV feature ensures more predictable and stable processing, enhancing efficiency in manufacturing. |
| TSR 20CV | Similar to TSR 20, this grade also incorporates the constant viscosity (CV) property. TSR 20CV provides the cost-effectiveness of TSR 20 while offering improved processing consistency, making it suitable for large-scale production. |
Each type of TSR is designed to meet specific industry standards and user requirements, allowing manufacturers to select the most appropriate rubber for their particular product specifications and processing needs.
