Ceramic Grade CMC: High-Performance Binder & Thickener for Ceramic Industry

Introduction: Trusted CMC Supplier for Ceramic Excellence

Qingdao Unionchem Co.,Ltd. is a leading manufacturer of ceramic grade Carboxymethyl Cellulose (CMC), engineered for glaze suspension, green body reinforcement, and slip casting applications. With ISO 9001 and CE certifications, our CMC delivers exceptional bonding strength, suspension stability, and low sintering residue (<0.5%). As the global ceramic CMC market grows at 4.8% CAGR (2025–2030), we supply 3,000 MT annually to 20+ countries, empowering clients like Porcelanosa and Laufen to achieve 30% higher production efficiency and 25% lower defect rates.

Product Portfolio: Tailored for Ceramic Processes

Grade	Viscosity (2% Solution, cps)	Degree of Substitution (DS)	Key Applications
CR-LV	300–500	0.7–0.9	Slip casting, sanitary ware注浆成型
CR-MV	1000–2000	0.8–1.0	Glaze suspension, tile glazing
CR-HV	2000–3000	1.0–1.5	Green body reinforcement, dry pressing

Technical Advantages: Elevating Ceramic Quality

1. Superior Suspension & Stability

• Glaze Uniformity: CR-MV grade prevents pigment settling by 90%, ensuring consistent color distribution and reducing batch variations .

• Shear-Thinning Rheology: Thins under shear (spraying/agitation) for easy application, then rethickens to prevent sagging.

2. Enhanced Green Body Performance

• Strength Improvement: CR-HV grade increases dry billet flexural strength by 25%, reducing handling breakage during production.

• Low Shrinkage: Controls drying shrinkage to 1.5%, minimizing cracking in large-format tiles .

3. Cost-Efficient & Eco-Friendly

• Low Dosage: 0.1–0.5% addition level achieves optimal results, reducing raw material costs by 20% vs. gum arabic .

• Clean Burning: Burns out completely at 600°C with no residual carbon, ensuring glaze clarity and reducing kiln pollution .

Industry-Specific Solutions

Glaze Formulations

• Tile Glazing: CR-MV grade improves flow properties, resulting in smooth, pinhole-free surfaces with 30% higher gloss (Case Study: Spanish Tile Manufacturer, 2024).

• Fancy Glaze: Enhances print definition in silk-screen printing, with sharp patterns and reduced color bleeding.

Green Body & Slip Casting

• Dry Pressing: CR-HV grade reduces die wear by 40% in porcelain tile production, extending equipment lifespan.

• Sanitary Ware: CR-LV grade enables complex shape casting with uniform wall thickness, reducing firing warpage by 25%.

Technical Ceramics

• Electronic Ceramics: Ultra-pure CR-HV (purity ≥99.5%) ensures minimal impurity introduction, critical for dielectric properties.
