What Are the Five Things to Confirm Before Selecting a Rubber Grade?
Quick AnswerConfirm the application and operating conditions, incumbent raw rubber grade, critical quality specifications, actual mill and procurement authority, then compare delivered cost and validation lead time.
Technical Sequence
The incumbent system serves as the comparison baseline: record whether compounding is in-house, the current grade, quality specifications, process changes unacceptable to the customer, and end-product standards. Assess substitutability first, then calculate the price differential.
Supply Sequence
Verify the producing mill and consecutive COA, availability by month, packaging, delivery lead time, quantity, and logistics routing. Candidate grades must map to clearly assigned sample testing and approvers.
