Impact of Soft Foam Catalysts on Foam Open-Cell Structure

Introduction The open-cell structure of polyurethane (PU) foams is a critical property that significantly affects their performance in various applications. Soft foam catalysts play an essential role in influencing this structure by affecting the reaction kinetics and gas evolution during foam formation. This article explores how different types of soft foam catalysts impact the open-cell nature of PU foams, examines the mechanisms behind these effects, discusses…
