The performance and classification of PVC soles are described

PVC is a polar non-crystalline polymer, there is a strong force between the molecules, is a hard and brittle material; Low impact strength. After adding the impact modifier, the elastic particles of the impact modifier can reduce the total induced stress of the silver stripes, and use the deformation and shear bands of the particles themselves to prevent the expansion and growth of the silver stripes and absorb the impact energy in the body of the transfer material, so as to achieve the purpose of impact resistance. The particles of the modifier are small, so that the number of the modifier per unit weight or unit volume can be increased, so that the effective volume can be increased, thus enhancing the ability to disperse stress. At present, organic impact modifier is widely used.
PVC soles are generally divided into two kinds. One is made of soft PVC mixing, adding an appropriate amount of foaming agent to make sheets, foam molding into foam plastic, made of foam PVC soles; The other is to use injection molding machine with various molds made of PVC soles.
PVC soles have good physical and chemical properties. From an intuitive point of view, it can be said to be a plastic type of material, characterized by light, strong gloss, but lack of texture.
PVC soles are generally suitable for fashion shoes. Because of its thin and light characteristics, the shoes have a strong three-dimensional perception and can highlight the unique smooth lines of fashion shoes, so as to appear more classy.
