NNPB (Non-Nucleated Polymer Blends) technology is primarily associated with the research and development efforts of various organizations and institutions, but it is notably linked to the work of scientists and engineers in fields related to materials science and polymer engineering. There isn't a single "owner" of the technology, as it is often patented or developed collaboratively by multiple entities, including universities and companies specializing in polymer materials. For specific ownership details, one would need to refer to patent filings or industry reports related to NNPB advancements.
