In industrial manufacturing, RSS 3 Natural Rubber (Ribbed Smoked Sheet Grade 3) plays a vital role—especially in the production of tires, conveyor belts, and gaskets. Known for its strength, elasticity, and reliability, it remains one of the most widely used rubber types across the globe. In this article, Ngoc Chau Natural Rubber explores what makes RSS 3 the industry standard, why it’s preferred by manufacturers, and how to choose the right grade and trusted supplier.
What Is RSS 3 Natural Rubber?
RSS 3 stands for Ribbed Smoked Sheet Grade 3, a type of natural rubber sheet produced by coagulating latex and then air-drying it after smoke-curing. It belongs to the RSS family (RSS 1–5), with Grade 3 striking the balance between cost, performance, and processing quality.
RSS 3 is characterized by:
-
Uniform ribbed sheets
-
Smoke-cured finish
-
Light to medium brown color
-
Minimal foreign matter and contamination
It is governed by global standards such as ISO 2000:2014 and TCVN 3769:2016 in Vietnam, making it suitable for demanding industrial use.
Key Specifications of RSS 3 Natural Rubber
When choosing rubber for technical applications, precise physical and chemical parameters matter. At Ngoc Chau Natural Rubber, RSS 3 is manufactured under strict quality control:
| Property | Typical Result | Standard |
| Dirt Content | 0.007% | ISO 249:2016 |
| Ash Content | 0.20% | ISO 247-1:2018 |
| Volatile Matter | 0.44% | ISO 248-1:2018 |
| Nitrogen Content | 0.37% | ISO 1656:2019 |
| Wallace Plasticity (P₀) | 47.3 | ISO 2007:2018 |
| Plasticity Retention Index (PRI) | 88 | ISO 2930:2017 |
| Mooney Viscosity (ML 1+4, 100°C) | 89.2 | ISO 289-1:2015 |
These specs ensure RSS 3’s resilience, elasticity, and durability under industrial stress.
Applications of RSS 3 in Manufacturing
