ZnO
Zinc oxide AY powder is produced by Cathay Chemical using state-of-the-art equipment, calcined at a high temperature of 1200°C. Utilizing a sophisticated production process, it delivers exceptional quality and ultra-high purity, as the volatile matter typically contained in zinc oxide powder has been completely incinerated. It serves as an essential raw material for the manufacturing of premium black and dark-colored tires, rubber cables/wires, and insulation equipment. Furthermore, it acts as a vital vulcanization activator for rubber, as well as a high-purity, feed-grade ZnO additive that provides an indispensable essential trace element to promote animal growth. It is also highly suitable for the production of high-grade ceramics, tiles, mosaics, sanitary ware, and enamelware, being particularly renowned as an excellent flux for glaze and glass manufacturing.

NaHSO2 • CH2O·2H2O
CATHAYLITE-C is a proprietary brand of Cathay Chemical, with the chemical name Rongalite C or Sodium Formaldehyde Sulfoxylate. It is a powdery white crystalline solid containing water of crystallization; if excessively dehydrated, its apparent purity may exceed 100%. When exposed to air, it readily absorbs moisture and decomposes, releasing a characteristic garlic-like or pungent odor during deliquescence. As a powerful reducing and bleaching agent, CATHAYLITE-C is ideal for use in liquid solutions below 80°C. It also serves as a polymerization raw material and an additive in synthetic rubber production during organic chemical synthesis.

ZnO
Grade 3A is the premium grade among our Company's zinc oxide product lines, boasting an ultra-high purity of up to 99.8%.
Zinc oxide powder is a fluffy white fine powder with unique properties, manufactured through the high-temperature evaporation and oxidation of metallic zinc.
Exhibiting excellent heat resistance, it serves as a reinforcing agent in rubber formulations to significantly improve their durability and performance. In the glass manufacturing process, zinc oxide powder acts as an essential flux and effectively counteracts the adverse effects of thermal expansion and contraction.
In the electronics industry, zinc oxide powder leverages its unique characteristics; thus, beyond its widespread application in the electronic copying paper market, it is extensively blended as a core ingredient in the raw materials of various electronic components, such as ferrites (electromagnets), semiconductors, and transducers.
