TSR 20 CV Technically Specified Rubber

TSR 20 CV is a Technically Specified Rubber with Controlled Viscosity, manufactured from either field-grade coagulum or unsmoked sheets. The Mooney Viscosity of TSR 20 CV is set around a value of 65 (+7,-5). When compared to TSR 10 CV, TSR 20 CV contains a higher dirt content, indicating variations in manufacturing and refining processes.

Globally, rubber-producing nations adhere to their own TSR standards, ensuring alignment with the international ISO guidelines. Notably, Thailand follows the STR designation, while Indonesia and Malaysia opt for the SIR and SMR designations, respectively.

Distinguishing Features and Benefits of TSR 20 CV:

  • Technological Properties: TSR 20 CV adheres to rigorous technical standards, marking its utility for specific industrial and specialized applications.
  • Mixing Characteristics: Efficient breakdown properties provide an optimal mixing process, translating to heightened production outcomes.
  • Viscosity Control: TSR 20 CV’s viscosity remains consistent across batches, assuring uniform performance and quality standards.
  • Operational Efficiency: By virtue of its specific viscosity and textural properties, TSR 20 CV can lead to operational cost benefits by simplifying processing stages and ensuring consistent output quality.
  • Non-scorch Properties: Given its composition, higher curing temperatures can be employed without incurring the risks associated with rejects.
  • Additional Benefits: Superior mixing efficiency, streamlined production processes, durability against common wear, and bolstered green strength.

Applications of TSR 20 CV:

Given TSR 20 CV's specialized properties, it is engineered for applications that demand precision, resilience, and consistent performance. While potential applications encompass:

  1. Mechanical mountings
  2. Railway buffers
  3. Vehicle suspension systems
  4. Conveyor belt covers
  5. Automotive components

To understand the differences and find possible alternatives, one might consider examining other grades like TSR 10 CV.
