METHOCEL™ A4M Food Grade
METHOCEL™ A4M Food Grade is a medium–molecular weight methylcellulose thickener. It yields a viscosity of 4,000 cPs at 2% in water.
METHOCEL™ A4M is a water-soluble methylcellulose polymer used as a thickener, rheology modifier, binder, and film former. This cellulose ether product complies with common food standards and is meant for applications that may contact food, such as packaging. Thus, it may be used as a binder for thickening additives in packaging inks and coatings. METHOCEL™ A4M solutions are thixotropic in nature, create good lubricity and workability, and exhibit outstanding stability in extreme pH.
Specifications
Methoxyl, %: 27.5–31.5 Sodium chloride, max %: 1.5 Viscosity (2% in water at 20°C), cPs: 3,500–5,600
Primary Chemistry: Methylcellulose (MC)
Features & Benefits
Food contact approved Yields optimum performance at a lower concentration Water-soluble No ionic charge pH stable Exhibits reversible thermal gelation High lubricity Superior binding properties Thermoplastic polymer Excellent stability in pH 2–13
Problems Solved
Insufficient viscosity or storage stability of inks or coatings Inadequate certifications for food-contacting applications Defects in extruded ceramics caused by low green strength Loss of viscosity during storage of acidic or alkaline formulations Poor cling of adhesives or paints to vertical or overhead surfaces
Applications
METHOCEL™ A4M Food Grade is ideal for ink, coating, cleaner, and ceramic applications. Learn more about METHOCEL™ A4M Food Grade applications and functionality on our dedicated cellulosics website. Click Here!
