Foaming Regulator for PVC Foaming Shoes
Introduction: PVC foaming regulator is a regulator that increases the pressure and torque of the PVC melt, thereby effectively increasing the cohesion and homogeneity of the PVC melt, and making the resulting PVC products more compact.
Product Description: Foaming regulator for PVC foaming shoes can promote THE melting of PVC, improve the surface finish, improve the elasticity of melt, enhance the elongation and strength of melt.It is beneficial to cover bubble and prevent bubble hole collapse.The molecular weight and amount of foam modifier have a great influence on the density of foam sheet: with the increase of molecular weight, the melt strength of PVC increases, the density of foam sheet can be reduced, which has the same effect as the amount of modifier.However, this effect does not have a linear relationship, and the effect of increasing molecular weight or increasing dosage on decreasing its density is not very obvious, and the density will tend to be constant.PVC foaming regulator and foaming agent, and important relationship between the density of foamed sheet with foaming regulator is a balance, in which a balance, the density of foamed sheet is not affected by the influence of foaming agent content, are held constant, also increase dosage of foaming agent is not reduce its density, the cause of this phenomenon is under a certain amount of foam regulator dosage, PVC melt strength is limited, too much gas bubble hole collapse or merger.The use of PVC foaming regulator has also been introduced to us above. It is essential for us to process PVC products for this product, so we should fully understand it and use it correctly so as to bring us good results
