Blending & Packing

Butynediol ethoxylate is manufactured via precision-controlled alkoxylation (ethylene oxide addition), ensuring batch-to-batch consistency. The process undergoes multiple quality checkpoints:

Raw material analysis (purity >99.8%, heavy metal ISO 17025 lab)
Ethoxylation: Catalyst optimization for chain length control (proprietary process, US patent referenced)
Fractional distillation separates desired molecular weight
QC: GC-MS, FT-IR, and ISO 9001/14001 compliance

BEO is available in multiple EO grades according to client requirements; customized chain length and purity are also supported.
