Most insulation foams don't perform to the highest specifications because their cell structure causes poor dimensional and heat stability. The EMS Griltex range of copolyesters improves the long-term thermal stability, the dimensional stability (by reducing shrinkage and expansion) and compatibility with common adhesives like EVA. What's more, the Griltex range can be used to replace PVC in NBR/PVC compounds, reduce water vapour permeability end encourage the formation of smaller cells. The EMS Griltex range is available exclusively in the UK through Fibrecore.uk.com. For details, contact Tom Mallens on tom@fibrecore.uk.com.
