In today’s competitive industrial landscape, businesses demand materials that don’t just perform, they endure, adapt, and deliver consistent quality under pressure.

What is SIR 20?

SIR 20 is a standardized grade of natural rubber produced in Indonesia, widely recognized for its durability and versatility. It is made from processed field latex and cup lump, forms of raw natural rubber collected from plantations. This type of rubber is ideal for heavy-duty industrial applications, especially in sectors that require materials capable of withstanding extreme wear, pressure, and environmental challenges.

At PT Karet Batin Delapan, our SIR 20 rubber is crafted with precision to meet and exceed international expectations. Our processing methods ensure a consistent blend that results in a product with high tensile strength, superior elasticity, and long-lasting durability, essential qualities for businesses that demand reliability and performance.
