Hydroxypropyl methyl cellulose is a non-ionic polymer compound with good water retention properties, which is widely used in textiles, food, cosmetics and other fields. Refined cotton, on the other hand, has become an important raw material for many textiles because of its consistent length, moderate fineness, softness and breathability. Since hydroxypropyl methyl cellulose and refined cotton are often mixed in the textile production process, what are the benefits of refined cotton.

Hydroxypropyl methyl cellulose (HPMC) raw material is refined cotton benefits mainly include the following aspects:

Improve water retention performance

Refined cotton can improve the water retention rate of hydroxypropyl methylcellulose mixture. The experimental results showed that when the content of refined cotton was 20%, the mixture had the highest water retention rate of 73.2%. As the content of refined cotton increased, the water retention rate gradually decreased, but still remained at a high level.

Gypsum based putty

Improvement of viscosity properties

At low contents, refined cotton is able to increase the molecular weight of the blends, thus improving their viscosity. However, when the refined cotton content exceeds 30%, the viscosity of the mixture decreases, as the high content of refined cotton may affect the intermolecular forces of the mixture, leading to its loose structure.

Improved thermal stability

The addition of refined cotton also improves the thermal stability of hydroxypropylmethylcellulose. Experiments have shown that the mixture shows better thermal stability with less weight loss after being heated to 240°C and maintained for 10 minutes.

Plastering mortar

Enhance product quality

The quality of refined cotton directly affects the quality of hydroxypropylmethylcellulose. High-quality refined cotton produces cellulose with a whiter colour, less ash and better water retention. In addition, the number of washes and the addition of medium and small materials to the finished product also affect the quality of the final product.

In summary, the use of refined cotton as a raw material for hydroxypropylmethylcellulose can significantly improve the water retention, viscosity properties and thermal stability of the product, as well as the quality of the final product.

Hpmc manufacturer using refined cotton

Mikem is one of the most influential hpmc manufacturers, The raw materials of its products are high quality refined cotton to ensure that construction projects can be carried out smoothly, we focus on product development and upgrading, in the latest hpmc products, the upgraded HPMC has good anti-slip effect, good anti-sagging effect, good mechanical pumping performance, anti-slip function and ultra-long open time of construction, which make our products more competitive, which is one of the reasons why they are popular with customers, for more questions or direct order, please contact us!
