Features & Chemical Properties

Ammonium Per Sulphate is recognized for its high purity, strong oxidizing nature, and water solubility (80 g/100 ml at 25C). The compound decomposes before boiling, releasing gases like ammonia and nitrogen oxides. With a fine powder consistency, APS is also available in lumps or granules on request. Its acidic nature is indicated by a pH of about 1.5 for a 10% aqueous solution.

Safe Storage & Handling

Store APS below 25C in a cool, dry, and well-ventilated area, away from strong acids, bases, reducing agents, and combustible materials. The product is supplied in robust HDPE bags lined with polybags to maintain integrity and minimize moisture (<0.2%). Handle as per local guidelines for oxidizing agents, referencing its Hazard Class: Oxidizing solid (UN No: 1444).

Applications & Usage

APS is widely employed in polymerization as an initiator, in the electronics sector for printed circuit board etching, in laboratory analysis, and as a textile bleaching or cleaning agent. Its ability to decompose and release active oxygen radicals under controlled conditions makes it invaluable across multiple industrial sectors.

FAQs of Ammonium Per Sulphate:

Q: How should Ammonium Per Sulphate be safely stored for optimal shelf life?

A: Ammonium Per Sulphate should be stored at temperatures below 25C in a cool, dry, and well-ventilated space, away from strong acids, bases, reducing agents, and combustibles, to ensure its year-long shelf life and stability.

Q: What are the main industrial applications of Ammonium Per Sulphate?

A: This compound is primarily used as a polymerization initiator, etching agent in electronics (such as in printed circuit board manufacturing), in textile bleaching, as a cleaning agent, and for laboratory analytical procedures.

Q: When does Ammonium Per Sulphate decompose and what by-products are formed?

A: APS decomposes before reaching its boiling point, releasing gases such as ammonia, nitrogen oxides, and sulfur oxides. This decomposition can occur if the compound is subjected to high temperatures or improper storage.

Q: Where is Ammonium Per Sulphate most beneficially utilized?

A: APS is most beneficial in industrial settings, particularly in the chemical, electronics, textile, and laboratory sectors where its strong oxidizing and bleaching abilities are valued.

Q: What processes rely on Ammonium Per Sulphate as an essential component?

A: Processes like the initiation of free-radical polymerizations, printed circuit board etching, textile fiber bleaching, and scientific analysis use Ammonium Per Sulphate as a key reagent due to its ability to deliver active oxygen.

Q: How is Ammonium Per Sulphate typically packed and distributed for industrial use?

A: APS is packaged in 25 kg high-density polyethylene (HDPE) bags that are lined with inner polybags for moisture protection and safe transport; always follow local regulations for handling oxidizing agents.

Q: What are the benefits of using Ammonium Per Sulphate in industrial applications?

A: Its strong oxidizing properties, high water solubility, and ability to release oxygen upon decomposition make Ammonium Per Sulphate highly effective as a cleaner, bleaching agent, and chemical initiator, adding versatility and efficiency to various manufacturing and processing operations.
