Zinc Oxide AY Grade

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.

• Powder type

Sodium Formaldehyde Sulfoxylate (Rongalite )-Powder Type

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.
