Patents and research
Six decades of polyurethane development, protected by patents and validated by published research.
Active research directions
- Biocongruent Chemistry™ — materials engineered for durable service life and predictable end-of-life
- Halogen-free flame retardancy for PIR, spray foam, and rigid systems
- Reactive renewable polyols with primary hydroxyls for full network incorporation
- Catalyst and VOC reduction without losing cure speed or demold time
- Low-carbon polyurethane routes and measured bio-content by ASTM D6866
Patents and disclosure
MCPU holds patents covering reactive modifier chemistry, flame-retardant systems, and specialty polyurethane formulations. Customer-specific work is normally held as know-how under NDA rather than published.
For a current list of issued patents relevant to a product line, or for the technical basis behind a claim, contact us and we will provide what is public along with the supporting method.

Start with a non-confidential summary. We'll take it from there.
Tell us the performance target in non-confidential terms. If it is a fit we put an NDA in place, review your existing formulation and specification, then move to bench development, testing, customer trial and scale-up.
