Hydroxypropyl Methyl Cellulose (HPMC) for Tile Adhesive - Shijiazhuang Gaocheng District Yongfeng Cellulose Co., Ltd.

Hydroxypropyl Methyl Cellulose (HPMC) is a versatile chemical additive widely used in the construction industry, particularly for tile adhesives and plaster applications. As a key component in cement mortars, ceramic tile cements, and refractory coatings, HPMC enhances workability, water retention, and adhesion properties. This article provides an in-depth analysis of the product's features, technical specifications, applications, and the company behind this innovation.

Product Overview

Hydroxypropyl Methyl Cellulose (HPMC) is a modified cellulose ether derived from highly purified cotton fibers. The production process involves etherification under alkaline conditions, resulting in a white or milky white powder with exceptional functional properties. HPMC is renowned for its thickening ability, salt resistance, and dimensional stability, making it an indispensable ingredient in modern construction materials.
