We can produce 200,000 tons of chemical fiber oil and 200,000 tons of surfactants annually. We can supply more than one hundred types of products. Especially its polyester POY oil is an exclusively developed product in China and can totally replace imported hi-tech products.
Propylene glycol block polyether, also known as block polyether propylene glycol, is a class of block polyethers polymerised from propylene oxide, typically using propylene glycol as the initiator, with CAS number 9003-11-6.
This product range includes the commonly used Block polyether L61, Block polyether L62, and Block polyether L64. By adjusting the ratio of hydrophilic and hydrophobic segments, these compounds exhibit varying solubility and surface activity, catering to diverse application requirements.
Block polyethers are typically employed as low-foaming detergents, defoamers, dispersants, lubricants, and emulsifiers, finding extensive application in papermaking, fermentation, metalworking, pesticide formulation, coatings, and rubber processing. Owing to their low toxicity and excellent biocompatibility, these polyethers also serve as pharmaceutical excipients and emulsifiers in oral, nasal spray, eye drop, and topical formulations, ensuring uniform drug dispersion and stability. Within the textile industry, it enhances wettability, dyeing uniformity, and provides antistatic effects. In petrochemical applications, it serves as a crude oil demulsifier and pipeline scale inhibitor, concurrently improving secondary oil recovery efficiency.
Furthermore, block polyethers are employed in the defoaming process of artificial heart-lung machine blood circulation systems to safeguard equipment operational safety. Through precise control of molecular weight and hydrophilic-hydrophobic balance, L61, L62, and L64 cater to diverse system requirements ranging from strong defoaming and emulsification to mild wetting.
