Henan Nayu New Materials Co., Ltd. is a China-based specialty chemical manufacturer specializing in bio-based isocyanates and advanced polyurethane raw materials. Our core product portfolio centers on DDI (dimer diisocyanate, CAS 68239-06-5), a bio-based aliphatic diisocyanate engineered for high-performance polyurethane coatings, adhesives, and elastomers.
With REACH registration in the European Union and comprehensive technical documentation including TDS, COA, MSDS, and SDS, we support formulators and industrial buyers across Europe and Asia. DDI offers distinct advantages over conventional petroleum-derived isocyanates: superior UV stability, excellent weathering resistance (QUV-B 2000+ hours), low viscosity (170 mPa·s), and a low glass-transition temperature (~ -198°C) enabling flexible, crack-resistant films.
In addition to our isocyanate business, our R&D team maintains active research in hydrogen-based energy materials, including α-aluminium hydride, a next-generation solid hydrogen storage material.
We provide 100g evaluation samples with full technical support for qualified industrial buyers. Contact us to explore how bio-based DDI can enhance your formulation performance while meeting sustainability and regulatory targets.
