HYDROXYPROPYL CELLULOSE
Product DescriptionSIDLEY H-HPC is a series of off-white powders that is non-ionic cellulose ether. It is soluble in water below 38ºC and many polar organic solvents. It has different viscosities. It has many excellent properties. For example,It has organic solvent solubility, thermoplasticity, and surface activity with the thickening and stabilizing properties.And Its solution has low surface and interfacial tensions.
