Hydroxypropyl Methyl Cellulose (HPMC) is a versatile chemical additive that plays a critical role in modern construction materials, particularly in tile adhesives and plaster formulations. This article explores the technical specifications, functional advantages, and industrial applications of HPMC, while highlighting its significance in construction innovation. For more information, visit the official HPMC product page.
HPMC is a modified cellulose ether derived from high-purity cotton fibers through a specialized etherification process under alkaline conditions. It is widely used as a chemical auxiliary agent in construction due to its exceptional properties such as thickening ability, salt resistance, and water retention. The product is available in white to off-white powder form, with a particle size of 100 mesh (98.8% pass rate) and special specifications ranging from 40-60 mesh. Its apparent density is typically 0.25-0.70 g/cm³, while its specific gravity ranges between 1.26-1.31.
