Investigation of non-acoustical parameters of compressed melamine foam materials

A series of careful non-acoustical parameters measurements using 5 ‘Illtec’ melamine foam and 10 ‘Basotect TG’ melamine foam samples have been made. Flow resistivity, tortuosity, porosity, viscous characteristic length and thermal characteristic length of two types of compressed melamine foam materials with different foam magnifications have been investigated. It has been found that a relationship between the flow resistivity, fibre equivalent diameter and bulk density exists for each of the compressed melamine foam materials. This paper also discusses relationships between the non-acoustical parameters and compression rates in the compressed melamine foam media.
