Why OEMs choose us
Engineered for direct OEM supply
Core team with national research background
Our R&D and engineering leads come from national research institutes and rail-transit equipment R&D units. We control the full chain from molecular design to engineering validation in-house.
Triple certification · direct OEM access
ISO 9001, IATF 16949 and CRCC all in place; National High-tech Enterprise, contributor to 5 national standards, 30+ core patents.
Cost advantage vs. international benchmarks
Proprietary formulations benchmarked against Sabic / Lanxess / DuPont grades — matched or exceeded performance, 10–30% lower price, shorter lead time.
Owned compounding · custom formulations
Four MD-65D twin-screw lines + MD-35 formulation pilot, imported automatic dosing. 500 kg sampling MOQ, ±5% batch-to-batch stability in mass production.
R&D Frontiers
