Hydroxypropyl methylcellulose (HPMC) is a versatile polymer with applications in a variety of industries, including pharmaceuticals, construction, food and cosmetics. The raw materials used in HPMC synthesis are derived from natural sources and undergo a series of chemical modifications to obtain the desired properties.
