From Plating to Polymers: HPA & SHP That Perform
Hypophosphorous acid (HPA, H₃PO₂) is a versatile inorganic acid with applications across a wide range of industries. At Wintzell & Fried, we supply high-quality, fully REACH-registered HPA, ensuring full compliance with EU chemical regulations. In metal treatment, HPA is commonly used in electroless plating to reduce metal ions and create uniform coatings, resulting in smooth, high-quality finishes and consistent performance. Its reducing properties also make it valuable in chemical synthesis, where it aids in the production of specific organic compounds. In agriculture, HPA derivatives are sometimes used as stabilizers in plant growth regulators, improving formulation stability and shelf life while supporting higher crop yields and quality. Additionally, HPA can serve as a stabilizer in polymer and resin production, enhancing the durability, reliability, and overall performance of the final products.
The sodium salt of HPA, sodium hypophosphite (SHP, NaH₂PO₂), is another key compound widely used in electroless nickel plating. As a reducing agent, SHP ensures uniform nickel deposition on a variety of substrates, making it critical for applications in electronics, automotive, and other industrial sectors. Beyond plating, SHP is also used in polymer stabilization and flame retardant formulations, providing additional versatility for industries that demand high-performance materials. At Wintzell & Fried, we also provide REACH-registered SHP, ensuring safe and compliant use.
HPA is highly reactive and should always be handled with care. It is important to follow safety guidelines and use appropriate protective equipment. At Wintzell & Fried, we are committed to supporting our customers with comprehensive documentation, including SDS, TDS, and CoA, to ensure HPA can be used safely and efficiently.
