RXSOL is one of the leading Sodium hypophosphite  Exporters, Manufacturers, Suppliers, and Producers in Vadodara, Chennai, Ahmedabad, Haldia, Kochi, Visakhapatnam, Kolkata, surat, Mumbai India.

Sodium hypophosphite (NaPO2H2, also known as sodium phosphinate) is the sodium salt of hypophosphorous acid and is often encountered as the monohydrate, NaPO2H2·H2O. It is a solid at room temperature, appearing as odorless white crystals. It is soluble in water and easily absorbs moisture from the air.

10039-56-2 (monohydrate) check

Sodium hypophosphite should be kept in a cool, dry place, isolated from oxidizing materials. It decomposes into phosphine which is irritating to the respiratory tract and disodium phosphate.

Uses

Sodium hypophosphite is mainly used for electroless nickel plating (Ni-P). With this method, a durable nickel-phosphorus film can coat objects with irregular surfaces, such as in avionics, aviation, and the petroleum field.

Sodium hypophosphite is capable of reducing nickel ions in solution to metallic nickel on metal substrates as well as on plastic substrates. The latter requires that the substrate is activated with fine particles of palladium. The resulting nickel deposit contains up to 15% phosphorus.

It can be used as a food additive.

APPLICATION

1. electroless plating agent: through electroless plating metal surface with corrosion resistance, wear resistance, uniform density, solid nickel-phosphorus alloy coating, can replace stainless steel materials, widely used in electronics, machinery, petroleum, chemical, aviation, navigation, food and medicine, and other industries.

2. Metallize the surface of non-metallic materials such as plastics, ceramics, glass, and quartz.

3. water treatment, preparation of various industrial preservatives, and oil field scale inhibitors.

4. food, industrial boiler water additives.

5. can be used as a catalyst for chemical reaction, and stabilizer.

6. It can be used as an antioxidant, anti-decolorization agent, dispersant, textile finishing, and pharmaceutical industries.

Application: 

Mainly used as a reductant in the chemical plating process, AdSense and uniform nickel-phosphorus film can be obtained on both large equipment and tiny components, as well as articles with complicated external shapes such as convex-concave lines or internal walls with deep hollows. Also used on the surface of non-metals such as plastics, ceramics, glass, Etc. The film possesses surface hardness and abrasion resistance. Widely used in electronics, aviation mechanisms, and petroleum fields. Additionally used as an interface activator, an M.W. Moderator, a Thermo-stabilizer for synthetic resins.
