Hydroxypropyl starch ether (HPS) is a white fine powder obtained from natural plants through modification, high etherification and spray drying, without plasticizer.

Hydroxypropyl Starch Ether (HPS) serves several key functions. It is a white fine powder derived from natural plants, commonly abbreviated as HPS, and is widely used in industrial and construction fields. Its primary roles include:

For our country, the demand for polyvinyl alcohol remains relatively stable, with current apparent consumption at around 500,000 tons. In industries such as adhesives and PVB fibers, the application volume of polyvinyl alcohol is significant. With the sustained development of China's economy, the market demand and export volume for high-count, high-density, and high-grade textiles continue to grow. At the same time, the high-end papermaking industry and oil extraction sector are also experiencing rapid growth.

Polyvinyl alcohol (PVA), as an important polymer, has a wide range of applications. It is commonly used in coatings, adhesives, fiber sizing solutions, and paper manufacturing industries.

The application of redispersible latex powder in water-based coatings is an important breakthrough in the field of building materials. This innovation not only improves the performance of coatings, but also contributes to the cause of environmental protection.
