As a white pigment filler of high quality, has a variety of uses. It can be used in plastic profile, paint, emulsion, powder, paper, cosmetics and chemical fiber. It can be used with both water and solvent systems. The different application and application systems have additional requirements in selecting organic coatings agents. Traditional TMP and peg are no longer sufficient to meet these requirements. They also have some negative effects, like the bubble problem. To obtain a satisfactory application treatment, it is important to use different organic treating agents according to the different USES for titanium dioxide. In addition to the different USES for titanium dioxide, there are also differences in titanium dioxide application performance requirements.
Plastics – Requirements on titanium dioxide
1. High viscosity extrusion/dispersion lubricant
As plastic products become stronger and cheaper, they add more color fillers. However, as the resin proportion decreases and compatibility between components becomes more challenging, it can cause the surface to be rough and unattractive. Consider the colormasterbatch that is commonly used in plastics: it’s made by extrusion of titanium dioxide and granulation after being kneaded with high temperature organic resins such as polyethylene wax or high-pressure polyester. It is necessary to use the least amount of carrier resin possible in order to moisten maximum titanium dioxide. This will help to achieve a higher concentration of white masterbatch while avoiding low resin compatibility. In order to produce masterbatches, titanium dioxide must have excellent lubrication and surface wettability properties. If not, it is difficult to granulate or disperse.
2. Temperature/weather Resistance
Before processing or forming, the vast majority of plastics products, regardless of their type, processing method or resin, must be in high-temperature melt with titanium dioxide and additives. Processing temperatures for plastics are around 200 degrees, or higher. The decomposition of some components at this temperature will cause pigment migration, porosity and a serious impact on the physical strength and surface quality of plastic products. Each component of the formula must have excellent temperature resistance. Besides, the UV resistance of most plastic products, such as plastic films, electrical appliances, used outdoors or in a healthy light environment must be taken into consideration. In PVC products, a stabilizer containing lead is added. This type of stabiliser is easily reacted with other active chemical substances at high temperature and produces black substances. Lead stabilizers cannot react with organic coating agents on titanium dioxide surfaces.
3. Dry powder fluidity/moisture resistant
As more and factories adopt continuous production line for plastics products, raw materials related to them (such a resins, fillers or pigments) are also utilizing transmission belts of vibration leakage sieves in order to automate the automatic measurement. Imagine that the flow rate of titanium dioxide dry is low. The powder will then get stuck in the belt of the transmission or block the screen hole. This can lead to titanium dioxide not being accurately measured and added smoothly.
