ZB-730 ZB-740 ZB-750 ZB-760
 Brief Introduction
PVC foam adjustment agent 7 series be made from acryl ate monomer by emulsion polym erization process, The Main characteristic is High melt strength and good plasticity lt is mainly used to improve the uniformity of the foaming hole, promote fusion and melt, improve the surface quality of the finished product.
When it is used as processing aid,it can enhance the melt strength,endow with better surface brightness.
It is white powder, it can be dissolved in ketene and chloroform, but not in water and alcohol.
