SVR CV50 (TSR CV50) Natural Rubber
– Vietnam Manufacturer

Yes. SVR CV50 and TSR CV50 both refer to a constant viscosity natural rubber grade with a typical Mooney viscosity target of 50 ± 5. “SVR” is commonly used for Vietnamese Standard Rubber, while “TSR” refers to Technically Specified Rubber in international trade.

For buyers, both terms are used to describe a controlled-viscosity natural rubber grade suitable for manufacturers that require stable processing performance.

SVR CV50 is produced with a typical Mooney viscosity target of 50 ± 5. This controlled viscosity range helps manufacturers improve consistency during mixing, extrusion, molding, and compounding.

For procurement teams, this means SVR CV50 is suitable when the formulation requires a lower constant viscosity grade compared with SVR CV60, while still maintaining stable processing behavior.

The main difference is the viscosity target. SVR CV50 has a Mooney target of 50 ± 5, while SVR CV60 has a Mooney target of 60 ± 5.

Buyers usually choose SVR CV50 when their compound formulation requires easier processing, lower viscosity, or better flow characteristics. SVR CV60 is normally selected when a higher viscosity grade is required for the final compound design.

Commercial export orders are usually handled by container quantity or agreed shipment lot. Samples are handled separately from commercial MOQ and may be arranged depending on stock, production season, and buyer requirements. Quotations are subject to available volume and APT final confirmation.

Yes. APT Rubber’s controlled production process helps maintain stable Mooney performance for up to 6 months, subject to proper storage conditions.

This is important for manufacturers because viscosity fluctuation can affect mixing behavior, processing stability, and production consistency. Stable Mooney performance helps reduce unnecessary production adjustment and supports better batch-to-batch control.
