This white paper addresses when and how to use performance additives. When properly selected, performance additives bring value and clear benefits to the application. They address manufacturing and process concerns to help maintain quality and consistency during compounding. The number of available additive options can be overwhelming to compounders and plant chemists. Therefore, a systematic approach to performance additive selection should use to define objectives clearly, such as better throughput, precise control of critical ingredients, lower costs with shortened mixing cycles, timely and complete dispersion, worker safety, and color control, to name a few.
