Polyvinyl alcohol (PVA) is a water-soluble polymer obtained from polyvinyl acetate through alcoholysis, hydrolysis, or ammonolysis, with good biocompatibility and biodegradability. There are hydrogen bonds between PVA molecules, which have good chemical and thermal stability; The molecular chain contains hydroxyl groups, which have strong hydrophilicity, film-forming properties, emulsifying properties, and solvent resistance. PVA microspheres can be used in fields such as blood perfusion, optical recognition, drug release, interventional therapy, encapsulation, and pH controlled release.

Beijing Biotyscience Co. Ltd can provide high-quality PVA microspheres with different particle sizes (5 um - 200 um), as well as PVA microspheres with different surface modifications, such as carboxyl PVA microspheres and amino PVA microspheres. The product has high repeatability between batches and is easy to surface modify and modify. It can meet various personalized material needs of customers, including research and development, experimentation, and production consumption.

 备注：PVA微球为模板法制备，PS为骨架，PET含量在75%以上。目前提供不了100%纯PVA微球。
