Abstract

Optical polishing pitch formulations include synthetic polymers or other synthetic resins. As alternatives to traditional optical pitches, these materials offer improved stability in use, storage, and processing. In addition, these pitch compositions may be masterbatched and manufactured with precision to ensure superior reproducibility and quality control in polishing performance.
