 TR28 titanium dioxide Guide 

 Tioxide TR28 is designed specifically for the plastics industry as a fine crystal rutile pigment with its surface coating makes it easy to spread and improve production efficiency and low amount of moisture absorption characteristics. 

 TioxideTR28 recommended for polyolefin masterbatch including polyethylene cast film production because of TR28 has excellent thermal stability, it is the ideal choice for high-temperature processing of plastics, can prevent mold mouth blemish left and the hole and so on.
