Hydroxypropyl Methylcellulose (HPMC) in Ceramics

HPMC plays a crucial role in the ceramics industry as a binder, plasticizer, thickener, and water retention agent. It enhances the workability, strength, and shaping properties of ceramic materials during processing.

Key Functions of HPMC in Ceramics:

  1. Binding Agent – Improves the adhesion of ceramic powders, ensuring uniformity and preventing cracks or deformation during shaping.
  2. Plasticizer – Enhances the plasticity of ceramic pastes and slurries, making them easier to mold and shape.
  3. Thickener & Rheology Modifier – Controls the viscosity of ceramic slurries, ensuring stable suspension and preventing sedimentation.
  4. Water Retention – Reduces water evaporation during drying, minimizing cracking and defects in the final ceramic product.
    Improved Green Strength – Provides mechanical strength before sintering, reducing handling damage and improving production efficiency.

Due to these benefits, HPMC is widely used in ceramic glazes, tile production, sanitary ware, and advanced ceramics, optimizing both processing performance and final product quality.

”Celopro®Cellulose Ether-Multi-functional additives”

Celotech’s cellulose ethers are versatile, water-soluble, and highly efficient. They have excellent burnout characteristics.

In ceramics, they act as binders that gel at high temps to boost cohesion, increase green strength, and prevent binder migration. They also serve as lubricants, emulsifiers, suspending agents, and surfactants.

In the production of honeycomb ceramics, the application of cellulose ether significantly improves the operability and dimensional accuracy of the product, reduces the scrap rate, and improves the overall quality of the product. These properties make cellulose ethers an indispensable additive in the ceramic industry. Celopro® cellulose ethers are mainly used as process auxiliaries for high-performance ceramics, with specific grades depending on the application.
