Standard Indonesian Rubber (SIR) is a type of natural rubber that is classified according to technical specifications. Here are some key details about SIR:

General Information

• Production: Indonesia produces approximately 2 million tonnes of rubber per year, primarily in North and South Sumatra, Riau, Jambi, and West Kalimantan. The country is the second-largest rubber producer in the world, after Thailand1.

• Export: About 85% of Indonesia's rubber output is exported, mainly to countries like Singapore, China, Japan, the USA, and Brazil.

Grades and Specifications

SIR is available in various grades, each with specific properties:

• SIR 3CV50: Maximum dirt content 0.03%, ash content 0.5%, nitrogen content 0.6%, volatile matter 0.6%, initial Wallace plasticity 30, plasticity retention index 60, Mooney viscosity 50 ± 5.

• SIR 3CV60: Similar to SIR 3CV50 but with a Mooney viscosity of 60 ± 5.

• SIR 3L: Maximum dirt content 0.03%, ash content 0.5%, nitrogen content 0.6%, volatile matter 0.8%, initial Wallace plasticity 30, plasticity retention index 75.

• SIR 5: Maximum dirt content 0.05%, ash content 0.5%, nitrogen content 0.6%, volatile matter 0.8%, initial Wallace plasticity 30, plasticity retention index 70.

• SIR 10: Maximum dirt content 0.1%, ash content 0.75%, nitrogen content 0.6%, volatile matter 0.8%, initial Wallace plasticity 30, plasticity retention index 60, Mooney viscosity 60 ± 5.

• SIR 20: Maximum dirt content 0.2%, ash content 1%, nitrogen content 0.6%, volatile matter 0.8%, initial Wallace plasticity 30, plasticity retention index 50, Mooney viscosity 60 ± 5.

Uses

• Tire Industry: A significant portion of SIR is used in the tire industry due to its high quality and consistency.

• Industrial Products: SIR is also used in the production of various industrial products such as gaskets, hoses, and other rubber items.

Challenges

• Yield: Indonesia's yield per hectare is lower compared to other top rubber producers due to older rubber trees and low investment capabilities of farmers.

• Processing: Indonesia relies on processed rubber products from abroad due to its underdeveloped processing and manufacturing plants.

These details provide a comprehensive overview of Standard Indonesian Rubber (SIR) and its significance in the global rubber industry.
