High-quality hydroxyethyl methyl cellulose (HEMC)

图片
H igh-quality hydroxyethyl methyl cellulose   (HEMC) Product Description HEMC (hydroxyethyl methyl cellulose)   is a common polymer compound that has many outstanding properties and applications. HEMC is a water-soluble, high molecular weight, powdered compound. HEMC is non-ionic and has good compatibility and stability. HEMC has excellent viscosity, flowability and solubility and can be used in a wide range of applications. With high water retention and durability, HEMC can improve the performance and stability of coatings, construction materials and other products. HEMC is mainly used in coatings, paints, adhesives, cement mortars, paper pulp, ceramics and pharmaceuticals. In coatings and paints, HEMC is commonly used as stabilizers, thickeners and anti-drip agents. In cement mortar, HEMC is usually used as a binder, water retainer and thickener. In medicine, HEMC is usually used as formulation and surfactant. Specification parameters The viscosity of HEMC Cellulose   u...

Hydroxypropyl Methylcellulose Product Description Hydroxypropyl Methylcellulose (HPMC for short) is an important chemical and building material additive obtained by chemical modification of natural cellulose, which has a variety of excellent physical and chemical properties and application characteristics. The main properties of HPMC  are as follows. Good solubility: HPMC has good solubility and swelling in water, which can be fully dispersed and dissolved in cement-based, lime-based, gypsum-based and other cement-based materials, increasing the fluidity and processability of the materials. Good viscosity adjustment ability: The viscosity of HPMC can be adjusted according to different production processes and application requirements, which can control its fluidity and processability in cement-based materials, and also improve its crack resistance and durability. Excellent water retention: HPMC has good water retention and moisture retention properties, which can slow down the evap...
