MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202541078044 A) filed by Vivek. R. Musrif; and Echo Friendly Acoustics Private Limited, Bangalore, Karnataka, on Aug. 17, for 'synthesis of nano-polyurethane foam from recycled polyethylene terephthalate for soundproofing applications.'
Inventor(s) include Vivek. R. Musrif.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to the development of a process for the synthesis of Nano-Polyurethane foam for soundproofing applications. It specifically relates to the development of a process for the synthesis of Nano-Polyurethane foam for soundproofing applications from recycled waste using Polyethylene Terephthalate (PET) plastic bottles and bio-based polyols via a Glycolysis Reaction. It particularly relates to the development of an optimized process for the synthesis of Nano-Polyurethane foam for soundproofing applications from recycled waste using Polyethylene Terephthalate (PET) plastic bottles and bio-based polyols via a Glycolysis Reaction, and a PU foam material which incorporates nanomaterials (Graphene or Graphene Oxide) that has substantially better properties than regular PU foam (without a catalyst for de-polymerization). It also pertains to the development of an optimized process for the synthesis of Nano-Polyurethane foam for soundproofing applications that can be scaled up to industrial standards."
