Product Description

 

Product Description

Ethyl Cellulose is a non-ionic,water soluble polymer from derived from cellulose through a series of chemical and physical processes. It has good stability to light, heat, oxygen and wetness, and is stable to chemicals.
It is resistant to alcali, dilute acid and salting liquid, soluble in many organic solvents, such as alcohol, ether, ketone, ester, aromatic hydrocarbon and halohydrocarbon etc. And it is 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.

Production Application

Conductive Silver Paste used in solar cells
 
Ethyl cellulose is the ideal binder for conductive silver paste used in solar cell, 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
