Chlorinated polyethylene (CPE) is a high molecular elastomeric material that produced by chlorinating HDPE.
It has excellent properties as flame-retardancy, weather-ability, lower-temperature flexibility, and high impact strength. It can be blended with other plastics and rubbers, and is mainly used at PVC impact modifier.
Titanium dioxide (TiO2) is the most widely used white pigment because of its brightness and very high refractive index.
The most important application areas of TiO2 are paints and varnishes as well as paper and plastics. Other pigment applications are printing inks, fibers, rubber, and cosmetic products.
