Hydroxypropyl Methylcellulose (HPMC) Product Details
Product Description
Hydroxypropyl Methylcellulose (HPMC) is a non-ionic cellulose ether derived from natural polymer materials through chemical modification. It appears as a white or off-white powder and is widely used as a thickener, emulsifier, stabilizer, film-forming agent, and water-retention agent in industries such as construction, pharmaceuticals, food, and personal care.
HPMC is known for its excellent water solubility, thermal gelation properties, and high viscosity, making it a key ingredient in tile adhesives, wall putty, self-leveling compounds, and pharmaceutical tablets.
Production Process
The manufacturing of HPMC involves the following steps:
- Alkalization – Natural cellulose (wood pulp or cotton) is treated with sodium hydroxide to swell the fibers.
- Etherification – The alkalized cellulose reacts with methyl chloride and propylene oxide to introduce hydroxypropyl and methyl functional groups.
- Neutralization & Washing – The reaction product is neutralized and washed to remove impurities.
- Drying & Grinding – The purified product is dried and ground into a fine powder.
- Quality Control & Packaging – The final product undergoes rigorous quality testing before being packaged.

Frequently Asked Questions (FAQ)
Q1: What is Sodium Gluconate, and how does it differ from other chelating agents?
A: Sodium Gluconate is a highly effective chelating agent that binds with metal ions, preventing scale formation and enhancing the performance of cleaning and industrial products. It is derived through the fermentation of glucose, making it a natural and eco-friendly alternative to synthetic chelating agents. Unlike other chelating agents, Sodium Gluconate is biodegradable and has low toxicity, making it a sustainable option for water treatment, concrete admixtures, and cleaning solutions. Its superior stability and versatility make it the preferred choice for industries seeking both high performance and environmental safety.
Q2: What is the minimum order quantity (MOQ)?
A: Our MOQ is 1 ton, with bulk pricing available for larger orders.
