Product Description

Product Description

Name: Ethyl Cellulose
Abbreviation: EC
Structural formula:

In the formula , n stands for degree of polymerization and R for -H or -C2H5 .

Characteristics:

Ethyl Cellulose is a kind of white grains or powder, having no smell or tastes . Its 5% soliquoid shows neutral to litmus test paper.It is resistant to alcali , dilute acid and salting liquid , soluble in some organic solvents , such as alcohol , ether, ketone , ester, aromatic hydrocarbon and halohydrocarbon , etc , and compatible to many celluloses , resin and nearly all plasticizers . Ethyl Cellulose has low combustibility, small hydroscopicity and good electric behavior . Its thin film and plastics have good mechanical strength and flexibility in a wide range of temperature .
 

Properties of Ethyl Cellulose used in conductive paste

 

Ethylcellulose is the ideal binder for conductive paste inks, due to its high purity, clean burn-out, adjustable rheological performance and outstanding batch-to-batch consistency

• Best performing ethyl cellulose with unique organo-solubility and outstanding stability due to advanced production process
• Good solubility and low impurities allows reduction of filtering costs
• Narrower and higher electrodes with sharper edges that contribute to high conversion rates for photovoltaic cells
• Formulation flexibility and reduced rheology adjustment costs

 

 

 

Properties of Ethyl Cellulose used in conductive paste Inks

Ethyl Cellulose is widely used in printing ink such as screen printing ink , magnetic ink , flexographic and gravure printing ink; Ethyl cellulose is used as an additive to control the viscosity and improve performance of ink formulations. Ethyl cellulose can also be used as a binder in these solvent based ink formulations. Ethyl cellulose forms films with remarkably good flexibility at low temperatures with excellent impact toughness. Ethel cellulose improves flexographic and gravure ink's abrasion and scuff resistance.
