In terms of technology and quality, PVC foaming regulator can improve the solution elasticity of the product during calendering and make smooth rolling; in pipe extrusion, it can improve the apparent quality, eliminate the phenomenon of "shark skin", and improve extrusion. out rate.
As a common additive, the use of PVC foaming regulators can be said to be very common, but what role can PVC foaming regulators play in the processing process?
Specifically for the process and products, the PVC foaming regulator can improve the melt elasticity during the calendering process, so that the remaining material between the two rolls smoothly; in the pipe extrusion, it can improve the apparent quality and eliminate the "shark skin" phenomenon. Increase extrusion rate; greatly reduce the number of "fish eyes" in the product when extruding transparently.
Increasing melt elasticity in injection molding, thereby reducing injection volume, reducing the "white streak" phenomenon, improving surface gloss, improving weld strength, and adding lubricity processing aids can improve release efficiency, speed up injection cycles, and increase output, to prevent the phenomenon of "blooming" caused by the precipitation of external sliding; in blow molding, it can improve plasticization, reduce the fish-eye phenomenon, improve the elasticity of the melt, and make the molding thickness more uniform.
