Product Description
Ethyl Cellulose For Conductive Silver Paste
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 uesed in conductive photovoltaic paste inks
Ethyl cellulose 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
