Main Types of Our Products
Indirect Method / French Process: Zinc Oxide 99.5%, 99.7%
Direct Method / American Process: Zinc Oxide 90%, 92%, 93%, 95%, 96%, 97%, 98%, 99%
Application
Zinc Oxide can be added into various materials and products, including plastics, ceramics, glass, cement, rubber, lubricants, paints, ointments, adhesive, sealants, pigments, foods, batteries, ferrites, fire retardants, etc.
Characteristics
1. The particle size is very small and well-proportioned so that it can be soluted with other elements very well, and lower the physical parametererror of the electronic component.
2. High purity, it is convenient to operate and better for the efficient use.
3. Other elements is very little, little affect for the electronic component, can reduce the error for the practical parameter.
