How to reduce the density of PVC Foaming Board?
Density is a very important index for PVC foaming board. Many customers come to us for lower density but same dosage and mechanical property at the same time. We highly recommend foaming regulator from Shandong Polymer additives, P-530, P-600, P-700.
Foaming regulator is a kind of PVC processing aid which much higher molecular weight. The function of general processing aid is to promote fusion and improve processability.
Foaming regulator can give your foaming board with small and uniform cell structure, high melt strength and melt flowability at the same time. The finish products will get lower density when using foaming regulator from Polymer additives .
P-530 can be used in thin foaming board with thickness below 5mm.
You can choose P-600 for your 5-15mm thickness foaming board.
If you are searching additives for your foaming board higher than 15mm, P-700 is the most suitable choice.
