HPMC for gypsum-based building materials
1. Introduction to HPMC Hydroxypropyl methylcellulose (HPMC) is an important water-soluble polymer compound widely used in construction, medicine, food, daily chemicals and other fields. It is made from chemically modified natural cellulose and has good water solubility, thickening, water retenti...Read more -
How does HPMC improve gypsum-based building materials?
Hydroxypropyl Methylcellulose (HPMC) is a non-ionic cellulose ether chemically modified from natural cellulose. Due to its excellent water retention, thickening and film-forming properties, HPMC has been widely used in the construction industry, especially in gypsum-based building materials. Gyps...Read more -
Effect of redispersible latex powder on the quality of putty powder
Redispersible polymer powder (RDP) is an important building material additive, widely used in putty powder, tile adhesive, mortar and other fields. It is a powder made of polymer emulsion by spray drying technology, which can be redispersed in water when used to form an emulsion with high bonding...Read more -
Necessity of adding cellulose to mortar and gypsum based products
Hydroxypropyl methylcellulose, referred to as: HPMC or MHPC. The appearance is white or off-white powder; the main use is as a dispersant in the production of polyvinyl chloride, and it is the main auxiliary agent for the preparation of PVC by suspension polymerization. In the construction proces...Read more -
Why is cellulose ether being widely used in pharmaceutical excipients?
Pharmaceutical excipients are excipients and additives used in the production of medicines and prescriptions, and are an important part of pharmaceutical preparations. As a natural polymer derived material, cellulose ether is biodegradable, non-toxic, and cheap, such as sodium carboxymethyl cellu...Read more -
Do you know about hydroxypropyl methylcellulose plant soft capsules and its colloid mill?
At present, the mature raw materials of plant capsules are mainly hydroxypropyl methylcellulose (HPMC) and pullulan, and hydroxypropyl starch is also used as raw materials. Since the beginning of the 2010s, HPMC has been applied in the Chinese plant capsule manufacturing industry, and based on it...Read more -
Do you know the performance of hydroxypropyl methylcellulose?
Hydroxypropyl methylcellulose is a kind of non-ionic cellulose mixed ether. Unlike ionic methyl carboxymethyl cellulose mixed ether, it does not react with heavy metals. Due to the different ratios of methoxyl content and hydroxypropyl content in hydroxypropyl methylcellulose and different viscos...Read more -
How does the smell of hydroxypropyl methylcellulose affect the quality?
What are the effects of odor size on hydroxypropyl methylcellulose: Synthesis of hydroxypropyl methylcellulose: Treat refined cotton cellulose with lye at 35-40°C for half an hour, press, crush the cellulose, and age properly at 35°C, so that the average degree of polymerization of the obtained a...Read more
