Physicochemical properties of sheet PVC produced by blister machine

The natural color is light yellow, translucent and shiny. The transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the dosage of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. Hard products have higher hardness than low-density polyethylene. Below polypropylene, whitening occurs at the inflection point. Stable; not easy to be corroded by acid and alkali; relatively resistant to heat.
