What is SVR 3L?
Quick AnswerSVR 3L is a Vietnamese natural rubber grade, commonly evaluated in formulations with color and cleanliness requirements; its suitability depends on contract specifications, COA, and finished-product testing.
Selection Rationale
Procurement discussions on 3L often center on color, impurity content, and formulation fit. It is not inherently manufactured to the constant-viscosity control target of CV60; the two should not be interchanged based on price or grade name alone.
Actual Procurement
Verify the producing mill, color shade, quality parameters, lot-to-lot consistency, packaging, and delivery schedule. If the customer designates the source or mill of the incumbent 3L, use it as the baseline for second-source verification.
