MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202521097927 A) filed by Dr. Ankita Mandar Durgawale; and Dr. Supriya Satish Patil on October 10, 2025, for “granular Composite For Wearable Weighted Products And A Method Of Manufacturing Thereof”.

Inventors include Dr. Ankita Mandar Durgawale; and Dr. Supriya Satish Patil.

The application for the patent was published on July 17, 2026, under issue no. 29/2026.

Abstract: ABSTRACT “GRANULAR COMPOSITE FOR WEARABLE WEIGHTED PRODUCTS AND A METHOD OF MANUFACTURING THEREOF” The invention discloses a h-eawveiyght, flexible granular composite and a method for its manufacture. The composite comprises a primary high-density sand component (Zircon sand), a secondary high-density granular component (steel pellets or microspheres), a moisture-curing polyurethane binder, and a silane coupling agent. The components are combined in specific proportions—preferably 55% Zircon sand, 30% steel pellets, 14% PU binder, and 1% silane agent—to achieve a bulk density above 4.0 g/cm³. The process involves precision silane treatment and controlled thin-film coating to ensure the particles remain distinct and flexible, making it an ideal non-toxic filler for wearable weighted products like wrist and ankle cuffs.
