High-Quality Aliphatic Polyurethane Acrylate Oligomer Suppliers & Factory serving Osaka

Aliphatic polyurethane acrylates utilize non-aromatic diisocyanates (such as IPDI, HDI, or H12MDI) that do not possess benzene ring conjugated systems. When exposed to prolonged sunlight, high operating temperatures, or UV irradiation, aromatic resins oxidize rapidly into quinoid structures that trigger severe yellowing and brittleness. Aliphatic grades maintain pristine optical transparency, superior elastomeric recovery, and long-term weatherability essential for exterior automotive plastics, smartphones, and optical films.

Ever Ray operates an automated DCS synthesis plant with rigorous raw-material qualification. Every batch undergoes Gel Permeation Chromatography (GPC) to verify narrow molecular weight distribution, Fourier-Transform Infrared Spectroscopy (FTIR) to ensure 100% isocyanate reaction termination, and Brookfield viscometry control within a narrow ±5% deviation. Certificates of Analysis (COA) specifying exact parameters accompany each shipment.

Direct ocean freight routes from Pearl River Delta ports (Nansha/Hong Kong) reach Osaka Port within 5 to 7 days. Standard export packaging comprises 200kg sealed steel drums or 1,000kg IBC totes, secured on fumigated ISPM-15 compliant pallets with complete weather-shrink wrapping, shock indicators, and moisture-barrier covers to protect resin integrity during marine transport.

Yes. We regularly supply oligomers pre-cut with specialized reactive diluents such as IBOA (for high Tg and low shrinkage), TPGDA, DPGDA, TMPTA, or HDDA. For VOC-free applications demanding low application viscosity, our synthetic chemists can modify polyol chain backbones or integrate hyperbranched topologies to lower native oligomer viscosity without sacrificing mechanical modulus.
