Acicular Titanium Dioxide, FTL series
Characteristics of Acicular Titanium Dioxide, FTL series
ISK has developed rutile-type acicular titanium dioxide by its own proprietary technology.
Utilizing its unique shape and hardness, the acicular titanium dioxide has been applied for reinforcing materials in plastics.
Due to physical strength of titanium dioxide, it can be hardly broken under strong mixing with resins.
Due to its small size and high aspect ratio, it is expected to be applied for small and thin devices to reinforce them.
Owing to neutral pH and extremely low impurities, it can be applied for various resins.
Reinforcement of plastics and ceramics
Paint, paper, rubber and catalysts
Friction material, filtration material

Table 2 Physical strength of acicular titanium dioxide
As it is difficult to evaluate strength of the very small particles of acicular titanium dioxide, Young's modulus of titanium dioxide is compared with other materials in the following table.
|Quartz||Potassium Titanate||Titanium Dioxide (Rutile)|
|Young's modulus (GPa)||52～111||27.6||289.4|
It is considered that strength of acicular titanium dioxide is larger than potassium titanate by ten times and quartz by 3-5 times.
