RSS3 Natural Rubber From Viet Nam

Introduction to RSS 3 Natural Rubber

Ribbed Smoked Sheet 3 (RSS 3) is a premium grade of natural rubber produced through the coagulation of latex, followed by rolling, drying, and smoking to create ribbed sheets with excellent durability and elasticity. Known for its high tensile strength, abrasion resistance, and consistent quality, RSS 3 is widely used in tire manufacturing (especially truck, bus, and passenger car tires), as well as in industrial products such as hoses, footwear, and shock-absorbing components.

As a leading supplier from Vietnam, Ngoc Chau Natural Rubber delivers RSS 3 that meets international standards, ensuring stable performance, competitive pricing, and a reliable supply for global partners in the automotive and rubber industries.

Key Characteristics of RSS 3 Natural Rubber

1. Exceptional Strength and Reliability

RSS 3 is recognized as a premium grade of natural rubber, valued for its high tensile strength, excellent abrasion resistance, and outstanding elasticity. These qualities make it a dependable material for industries requiring durable and high-performance rubber.

2. Traditional yet Refined Processing

This grade is produced through a meticulous process: fresh latex is coagulated, rolled into ribbed sheets, and then carefully dried and smoke-cured. The smoking stage not only enhances durability but also imparts the distinctive color and aroma associated with ribbed smoked sheets.

3. Quality Grading and Classification

The “3” designation indicates a specific international grading standard. While minor blemishes or small specks are permissible, RSS 3 must remain clean, structurally sound, and evenly smoked to meet export requirements and customer expectations.

4. Balanced Quality and Cost Efficiency

Combining consistent performance with competitive pricing, RSS 3 achieves an ideal balance of quality and affordability. Its versatility and reliability make it one of the most widely traded and sought-after natural rubber grades in global markets.

Manufacturing Process of RSS 3 (Ribbed Smoked Sheet 3)

RSS 3 natural rubber is produced through a traditional smoke-curing method designed to ensure durability, consistency, and compliance with international standards. The main steps in the production process include:

• Latex Collection – Fresh latex is tapped from Hevea brasiliensis trees early in the morning to maintain purity and reduce impurities.

• Coagulation – The latex is treated with formic acid or similar agents, causing rubber particles to solidify and separate from water.

• Sheeting & Rolling – Coagulated blocks are pressed into thin ribbed sheets that improve drying efficiency, prevent sticking, and simplify handling.

• Drying & Smoking – Sheets are smoke-cured in drying chambers, where controlled heat removes moisture, prevents mold, and gives RSS its distinctive brown color.

• Quality Grading – Each sheet is visually inspected following international grading standards. RSS 3 permits slight blemishes but guarantees high elasticity, strength, and cleanliness.

Applications of RSS 3

RSS 3 natural rubber is a versatile industrial material renowned for its durability, elasticity, and resistance to wear. Its wide range of applications spans multiple sectors:

• Tire Manufacturing – Serving as a core raw material for passenger cars, trucks, and off-road vehicles, RSS 3 is essential in producing treads and carcasses. Its high tensile strength and abrasion resistance ensure safety, performance, and long service life for tires.
• Industrial Products – Widely used in manufacturing rubber hoses, conveyor belts, gaskets, and shock absorbers, RSS 3 provides outstanding stability and resilience, even under demanding operational conditions.
• Footwear & Consumer Goods – From durable shoe soles to waterproof rubber products, RSS 3 enhances flexibility, elasticity, and water resistance, making it a reliable choice for everyday consumer applications.
