How to Evaluate an Alternative Impact Modifier Grade
How to compare an existing reference grade with an RC grade without implying chemical identity or universal interchangeability.
Short Answer
Evaluate an alternative grade in the same resin, formulation and processing conditions used for the current material. A similar result in one controlled formulation supports only formulation-specific evaluation and does not establish chemical identity or universal interchangeability.
Evidence hierarchy
Properties to compare
Evidence boundary
Use “Comparable Grade for Evaluation” or “Formulation-Specific Comparative Evaluation.” Comparative evidence does not establish chemical identity.

Controlled Evidence and Related Resources
Evidence scope: Application and comparative results are formulation-specific and are not guaranteed product specifications. Final grade selection and dosage must be validated in the customer's resin, formulation and processing conditions.
