Description
CSR, also known as block rubber, is graded based on specific technical parameters such as dirt content, ash content, nitrogen content, volatile matter, and properties of the rubber such as its Wallace Plasticity (PO) and its Plasticity Retention Index (PRI). CSR 10 are most widely used by the tire industries and made from cup lump also known as field coagulum. CSR L, made from field latex, has higher purity and is thus one of the most expensive block rubbers compared to CSR 5 and CSR 10, etc. CSR L grades are predominantly employed in the manufacturing of precision rubber products. To ensure the quality of CSR, all processing phases of raw materials are monitored and controlled for end-users. For a detailed overview of the specifications for each CSR grade, please refer to the table below.
