We have succeeded in forming needles of titanium oxide for the first time in the world using our unique technology, and have developed rutile-type white needle-shaped titanium oxide.
Taking advantage of its shape characteristics and hardness of titanium oxide, it is being applied to reinforcing materials, friction materials, etc.
Since it has the strength peculiar to titanium oxide, it is hard to break even against a strong share such as when kneading plastic, and maintains good performance such as reinforcing effect.
Although the long axis is short, the aspect ratio is high, so it is effective for small parts, thin-walled parts, etc. and has excellent surface smoothness.
Since it is neutral and contains almost no impurities, it can be applied to resin systems that dislike alkalis.

Technical Details & Test Data
- Strength Of Needle-shaped Titanium Oxide
Since needle-shaped TiO 2 is small in size (maximum major axis diameter is several µm), it is difficult to measure the strength of itself, so compare Young's modulus, which correlates with strength, with other materials. I will.
quartz Potassium titanate Titanium oxide (rutile crystal) Young's modulus (GPa) 52-111 27.6 289.4 There is a relationship between strength and Young's modulus by the following equation, and it can be said that a material with a large Young's modulus has high strength.
Strength = Young's modulus / 100-Young's modulus / 1000 formula (1)
Therefore, from the above table, titanium oxide is considered to have about 10 times the strength of potassium titanate and about 3 to 5 times the strength of quartz, and it can be estimated that this tendency also occurs in the fiber shape.
