Is CV60 a Higher Grade Than 3L?
Quick AnswerThey cannot be ranked as 'higher' or 'lower' grades. CV60 emphasizes constant viscosity and processing consistency, while 3L is typically used in applications where color and cleanliness are key concerns; the selection is determined by the customer's formulation.
Comparison Approach
First, identify the customer's current material and improvement targets: Mooney viscosity fluctuation, color, dirt content, processing energy consumption, or end-product performance; then conduct consecutive batch tests at the same mill or candidate mills.
Mandatory Verification
The nominal features of either grade do not imply that a specific batch is qualified, much less that material can be substituted without approval.
