SVR 3L (TSR 3L) Natural Rubber
– Vietnam Manufacturer
SVR 3L (TSR 3L) is a premium light-color technically specified natural rubber grade manufactured in Vietnam according to the TCVN3769：2016年 standard.
Produced from selected field latex, SVR 3L is preferred by manufacturers requiring low dirt content, controlled impurities, and consistent visual appearance for clean rubber products and appearance-sensitive applications.
APT Rubber can support SVR 3L buyers with COA, TDS, MSDS, export documents, and EUDR-aligned documentation upon request, subject to order scope and final factory confirmation.
Check our rubber price index for current procurement rates.
Bulk orders and long-term supply contracts may receive preferential pricing. Final quotation varies by volume and packaging.

What is SVR 3L (TSR 3L) Rubber?
Key Processing Benefits
-
Controlled cleanliness: Low dirt (<0.03%) and controlled impurity levels help reduce contamination risk in clean rubber compounds.
-
Better visual consistency: Light Lovibond color supports more uniform appearance in finished rubber products.
-
Reliable plasticity performance: Good Po and PRI values support stable processing under standard rubber manufacturing conditions.
