What Is SVR CV60?
Quick AnswerSVR CV60 is a constant viscosity natural rubber grade from Vietnam; it focuses on raw rubber viscosity and processing consistency. 'CV60' cannot replace contract specifications and batch testing.
Key Applications
Constant Viscosity Rubber (CV) is typically used where control of raw rubber viscosity fluctuation, mastication load, and mixing process window is required. Energy savings or reduced processing time are potential benefits that must be validated on the customer's production line and cannot be unconditionally promised.
Key Verification Points
Require clear identification of the actual factory, Technical Data Sheet (TDS), consecutive batch Certificate of Analysis (COA), sampling method, and Mooney viscosity test conditions; then conduct same-formula A/B testing against the incumbent grade. Upper and lower limits shall be governed by the specific contract and applicable standards.
