PU Foam Expansion Ratio

Polyurethane PU foam Expansion ratio is a versatile polymer essential to industries ranging from automotive and furniture to construction and insulation. The expansion ratio is a critical parameter that dictates the foam’s final density, mechanical strength, and overall performance. Accurately measuring this ratio is vital for quality control and maintaining manufacturing consistency. This guide details the methods, calculations, and factors necessary to master PU foam expansion measurement. What is PU Foam Expansion Ratio? PU foam expansion occurs when a liquid polyurethane mixture undergoes a chemical reaction, transforming into a solid foam with a significantly increased volume. Monitoring this process helps prevent defects such as shrinkage or uneven cell formation. How […]
