How SVR 3L rubber is produced

The production of SR 3L follows a strict process to ensure consistent quality and performance:

Latex collection & preservation

Fresh natural rubber latex is harvested from Hevea brasiliensis trees. Ammonia is added at the plantation to prevent premature coagulation during transportation.

Reception & preliminary treatment

The latex is first filtered at the plant to separate coarse particles such as bark, insects, and other debris. It is then diluted to the proper concentration for the coagulation stage.

Acid coagulation

Acetic acid or formic acid is added to coagulate the latex in coagulation tanks. This process forms a uniform rubber coagulum, separated from the serum.

Washing – rolling – granulation

The coagulum is repeatedly washed with clean water to remove impurities and residual serum. It is then rolled into thin sheets and granulated into small particles to increase surface area, allowing faster and more uniform drying.

Smoking & drying

The rubber is placed in smoking/drying chambers under controlled temperature and humidity. Purpose: to reduce moisture to standard levels, stabilize polymer structure, prevent mold and bacteria, and give the product its characteristic light color.

Classification & packing

After drying, the product is tested and classified according to standard rubber 3L technical standards (dirt, ash, nitrogen, PRI, Mooney, etc.). Qualified rubber is pressed into 33.33 kg bales, wrapped in clean PE film to ensure hygiene and quality.

Transport

Finished products are stored in cool, dry, well-ventilated warehouses, away from direct sunlight and high humidity. After quality inspection and shipment approval, Vietnam natural rubber SVR 3L is loaded onto pallets or directly into containers, with a capacity of 18–21 tons/20’DC containers.

Standardized packing process of SVR 3L natural rubber

Ngoc Chau Natural Rubber supplies S V R 3 L with packaging specifications that comply with international standards (ISO/TCVN), ensuring safe transportation, easy storage, and suitability for sea export.

Applications of rubber natural SVR 3L products

SVR 3L is a premium grade of natural rubber, known for its high purity, elasticity, tensile strength, and heat resistance. Thanks to these properties, it is widely used across industries that require superior quality:

FAQ – Rubber SVR 3L product related questions

Choosing the right rubber is crucial for your business. To help you better understand standard rubber (SVR 3L), we have compiled the most frequently asked questions from our customers. Find the answers you need below.

Can SVR 3L be blended with other rubber grades?

Yes. Many manufacturers blend SVR 3L with SVR 10 or SVR 20 to optimize cost, while still maintaining performance in tire or industrial rubber production.

What is SVR 3L rubber used for?

S V R 3L is used in the automotive industry for the production of tires and seals, medical products such as gloves and hoses, in consumer goods such as footwear due to its high purity, strength and elasticity.

How does SVR 3L differ from RSS?

SVR 3L has higher cleanliness, lighter color, and more stable Mooney viscosity compared to RSS1 & RSS3, which usually contains more impurities and has a darker shade.

Why is it called “3L”?

The term “3L” (Light Light Light) refers to a very light color of rubber, suitable for products where businesses require light tones and high purity.
