Features & Applications
Character & Applications
Soft white pigment
▷ Mohs hardness is much lower than TiO2 (about 3) ◁
When used on glass fiber reinforced plastic, it does not damage GF.
There is very little damage to the machine, reducing maintenance costs.
Example of use - Glass Fiber Reinforced Plastic
The addition of rutile TiO2 to PA66 reinforced with glass fiber significantly degrades mechanical properties.
However, the replacement of white pigments with ZnS with a Mohs hardness of 3 minimizes deterioration of properties.

Heat resistance improvement
▷ Helps to act as a metal deactivator ◁
It is the optimal additive for improving the heat resistance of polyolefin resins.
Captures and inhibits harmful metal ions that promote polymer oxidation.
Class that maximizes heat resistance performance: SACHTOTEC MD-300
Example of use - Glass Fiber Reinforced Plastic
The addition of rutile TiO2 to PA66 reinforced with glass fiber significantly degrades mechanical properties.
However, the replacement of white pigments with ZnS with a Mohs hardness of 3 minimizes deterioration of properties.
Solid lubricant
▷ It is a solid lubricant that can replace expensive molybdenum sulfide (MoS2) ◁
Low hardness, spherical particles can be used wherever a solid lubricant is required.
It is used as an additive to improve the performance of brakes and clutch linings.
UV absorption spectrum
▷ Specialized UV absorption wavelength ◁
Efficient and complete UV-curing with less energy; Saving photoinitiators
Example of use - UV Curing Paint
Compared to TiO2, the end of the light absorption spectrum is greatly shifted into the ultraviolet region.
With the efficient activation of the photoinitiator, the curing of the thicker white UV coating is faster and more complete.
