Ethyl Cellulose K70 K100 for cable coating
The coating material that protects wires and cables to meet the requirements of various use environments is called coatings for wires and cables.
There are many types of coatings. At present, coatings for wires and cables can be divided into four categories:
Protective coating-mainly used for waterproof, moisture-proof and corrosion-proof. Such as asphalt paint, rubber paint and nitrocellulose paint paint.
Fire-retardant coatings are mainly used as flame retardants, that is, to prevent the spread of flames. Such as non-expandable fireproof coating, intumescent fireproof coating, etc.
Anti-biological coatings---The main function is to prevent biological damage or growth. Such as anti-rodent paint, anti-termite paint, anti-mildew paint, etc.
Semiconductor coating-the main function is to shield or as the external electrode of the cable. Such as graphite paint.
The use of paint should be based on the requirements of the use environment, and comprehensive consideration should be given to its economic and manufacturability. When using organic solvents as diluents, you also need to pay attention to safety. It should be pointed out that in the wire and cable, the above-mentioned coating is not used as insulation, but it has a great effect on improving the service life or safety of the wire and cable and cannot be ignored.
Name: Ethyl Cellulose
In the formula , n stands for degree of polymerization and R for –H or –C2H5 .
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 .
