SVR 20 (TSR 20) Natural Rubber
– Vietnam Manufacturer
SVR 20 natural rubber is a cost-effective technically specified rubber grade used in tire, automotive, and general rubber manufacturing. Produced from field-grade coagulum / cup lump, SVR 20 is tested under Vietnam’s TCVN3769：2016年 standard for key parameters such as dirt, ash, volatile matter, initial plasticity, and PRI.
Compared with cleaner or lighter-color grades, SVR 20 is selected when buyers need practical processing performance, competitive pricing, and reliable bulk supply rather than premium appearance. It is commonly used in tire compounds, conveyor belts, molded rubber parts, rubber sheets, mats, footwear components, and other industrial applications.
APT Rubber supplies SVR 20 with COA-backed quality control and standard export documentation. For buyers requiring regulatory support, EUDR-related traceability documents may be discussed before order confirmation, subject to raw material availability and shipment requirements.
Bulk orders and long-term supply contracts may receive preferential pricing. Final quotation varies by volume and packaging.

| Parameter | TCVN 3769:2016 Limit | APT Internal Control |
|---|---|---|
| Dirt content (retained on 44µm aperture), % wt, max | ≤ 0.16 | < 0.16 |
| Ash content, % wt, max | ≤ 0.80 | < 0.80 |
| Nitrogen content, % wt, max | ≤ 0.60 | < 0.60 |
| Volatile matter content, % wt, max | ≤ 0.80 | < 0.80 |
| Initial Plasticity (P₀), min | ≥ 30 | > 30 |
| Plasticity Retention Index (PRI), min | ≥ 40 | > 40 |

What is SVR 20 (TSR 20) Rubber?
Key Processing Benefits
-
Cost-efficient compounding: lower-cost natural rubber option when the application does not require light color, tight cleanliness, or constant viscosity.
-
Practical mixing performance: works well in standard rubber compounding systems when the formulation is properly adjusted. I
