Industrial Grade Ethyl Cellulose

Ethyl Cellulose K70 K100 for aviation industry

The most important sector for the application of adhesive bonding technology is the aviation industry. Since the aircraft structure adopts the bonding process, it has obviously received a series of good effects such as reducing the structural quality, improving the fatigue life, and simplifying the process. Therefore, many countries have adopted the bonding technology as a new process for aircraft manufacturing.

In all modern airplanes, there are almost none that do not use the bonding process. In some aircraft, bonding has become the basis of the entire aircraft design. In the B-58 heavy-duty supersonic bomber, bonded wall panels accounted for 85% of the total aircraft area, of which the honeycomb sandwich structure accounted for 90%. The amount of glue used per plane exceeds 400kg, which can replace about 500,000 rivets. Each Boeing 747 jet airliner uses 2500 square meters of adhesive film and 450 kg of sealant.

【Introduction】

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 . Its specific density 1 . 07~1 . 18 , heat distortion point: 135~155degree centigrade , and fire point: 330~360 degree centigrade . Ethyl Cellulose 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 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 .
