SVR 20 natural rubber, a high-quality product from Vietnam, stands out for its exceptional versatility and performance across various industries. This grade of Standard Vietnamese Rubber (SVR) offers an ideal balance of durability, elasticity, and cost-effectiveness, making it a preferred choice for manufacturers worldwide.
Outstanding Features of SVR 20
SVR 20 natural rubber, produced in Vietnam, is a highly durable and versatile material recognized for its exceptional abrasion resistance and elasticity. Derived from secondary latex, SVR 20 exhibits a characteristic hardness, making it ideal for demanding applications such as tire manufacturing and industrial goods. Its low dirt content (maximum 0.16%) and high plasticity retention index (PRI ≥ 40) ensure superior cleanliness and long-term durability. These features, combined with its cost-effectiveness, make SVR 20 a trusted choice for industries worldwide.
Quality Control Parameters
SVR 20 adheres to strict quality control standards as defined by TCVN 3769:2016. Key parameters include:
-
Dirt Content: Maximum 0.16%, ensuring minimal contamination.
-
Ash Content: Maximum 0.80%, maintaining material integrity.
-
Nitrogen Content: Maximum 0.60%, enhancing elasticity and flexibility.
-
Volatile Matter: Maximum 0.80%, ensuring stability during processing and storage.
-
Plasticity Retention Index (PRI): Minimum 40, indicating excellent durability over time.
-
Initial Plasticity (Po): Minimum 30, ensuring resilience under stress.
These specifications guarantee that SVR 20 meets the rigorous demands of high-performance applications across various industries.
SVR 20 Transportation Specifications
To ensure safe handling and delivery, SVR 20 is packaged in standardized bales weighing approximately 33.33 kg each. The bales are shrink-wrapped or palletized using wooden or steel pallets for added protection during transportation. A standard 20-foot container can accommodate up to 600 bales, equivalent to approximately 20 metric tons of rubber. With efficient logistics systems in place, manufacturers can expect reliable delivery within 7–15 days of order confirmation.
