PVC ball is a kind of ball. Others include rubber ball, Pu ball, leather ball and PVC filled ball. Balls are suitable for playing on cement and asphalt fields.
PVC is polyvinyl chloride, which can be divided into soft PVC and hard PVC. Soft PVC contains softener (the difference between soft PVC and hard PVC), which is easy to become brittle and difficult to preserve; while hard PVC does not contain softener, so it has good flexibility, easy to shape, not easy to be brittle, non-toxic and pollution-free, and has a long shelf life.
PVC has the advantages of flame retardancy (flame retardancy value above 40), high chemical resistance (resistance to concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid and 20% sodium hydroxide), good mechanical strength and electrical insulation. However, its heat resistance is poor, with a softening point of 80¡æ, and it begins to decompose and discolor at 130¡æ, and precipitates HCI.
