  • Product Description
  • Function: This specification applies to the sulfur-promoting effect of natural rubber, synthetic rubber, and latex. It exhibits strong activating properties and, when used in combination with fatty acids, significantly enhances the activity of sulfur promoters.
    Process Description: Our company’s manufacturing process is the wet-process method. Before the reaction, toxic metals such as lead and cadmium are removed, resulting in a lower heavy-metal content in our zinc oxide compared to that of the highest-grade zinc oxide produced by the dry-process method.

    Product Description:
    Assay [(ZnO)x(ZnCO3)y] 85 ± 0.3%
    Lead (Pb) 5 ppm ↓
    Cadmium (Cd) 5 ppm ↓
    Iron (Fe) 200 ppm ↓
    Manganese (Mn ≤ 5 ppm)
    Copper (Cu) 5 ppm ↓
    Moisture (105℃) 2.0% ↓
    Appearance: White to slightly yellowish-green powder
    Specific gravity: 4.38.
    Specific surface area (BET method): 30–50 (㎡/g)
    Residue on 325-mesh sieve %: 0.1%

    Testing method:
    1. The zinc content of zinc oxide shall be determined according to the testing method specified in (CNS General No. 2203 K6175).
    2. Lead, cadmium, iron, manganese, and copper are directly analyzed by atomic absorption spectroscopy (A.A.).
    Packaging: 25 kg/bag.
    Storage conditions: Store in a cool and dry place; shelf life up to 2 years. The product must be stored sealed in a cool, dry, and well-ventilated area, and protected from direct sunlight.
