chloride is a wonderful material which can be compounded to produce
soles in various hardnesses and can be compact or microcellular. But
its higher weight maker is least preferred choice in high value high
performance shoes. With the advent of SUPER -EXPANDED PVC now it is
possible to reach a specific weight of 0.5, but this presents a poor
resistance or abrasion and hence it is used only for seasonal articles
such as beach, sandals and slippers. The soles are produced on air
blown machines using a foamed PVC compound.
