The demand for gelatin capsules/HPMC capsules for oral consumption has risen considerably due to its universal use without any fillers. In 2014, around 10%-15% of the USA’s supplements and medications were launched in capsule form, compared to just 5% in 2007.

HPMC is produced through the etherification of cellulose, a natural polymer obtained from plant fibers. By introducing hydroxypropyl and methyl groups, HPMC exhibits unique solubility and viscosity properties. The degree of substitution of these groups influences its behavior in different applications. HPMC is generally soluble in cold water, forming transparent and viscous solutions, which makes it particularly useful in formulations requiring thickening or stabilizing agents.

In recent years, the construction industry in China has undergone significant transformation, fueled by advancements in materials science and the growing demand for sustainable building practices. One of the key players in this evolution is Hydroxypropyl Methylcellulose (HPMC), a versatile cellulose ether widely used in various construction applications. As a crucial component of many building materials, HPMC has been pivotal in enhancing the quality and performance of products in China’s construction sector.

RDPs can be formulated from a variety of polymers, including styrene-acrylics, vinyl acetate-ethylene, and other copolymers. Each type of polymer confers different properties to the resulting mortar or adhesive. For instance, styrene-acrylic RDPs typically provide excellent adhesion and weather resistance, while vinyl acetate-ethylene powders are known for enhancing flexibility and elongation.

Hydroxypropyl methylcellulose (HPMC) is a versatile cellulose ether that has gained significant attention across various industries due to its unique properties and multifaceted applications. As a non-ionic polymer, HPMC is derived from cellulose, and its modification introduces different functional groups, making it suitable for a wide range of uses. The different grades of HPMC have varying physical and chemical properties, which allow them to cater to specific applications in pharmaceuticals, food preparation, construction, and many other fields.

The degree of substitution (DS) of HPMC, which indicates the amount of hydroxyl groups replaced with hydroxypropyl and methyl groups, can be tailored according to specific requirements. This customization allows manufacturers to create grades of HPMC that offer varying viscosity, solubility, and gelation properties, making it a truly adaptable compound.
