Black and white conductive folding film product parameters:

Specific model:

The black and white conductive hemming film is made of a single layer of carbon-containing polyethylene, and the appearance is opaque, and the conductivity is not affected by humidity. Repeated use will not pollute the components that come into contact, and can be grounded. It is usually used for material handling, packaging and storage in the electronics and chemical industries.

In the plastics industry, black and white conductive hemming films are used to produce conductive or static dissipative products. Since there is almost no inherent conductivity of plastic resins, it is necessary to add special fillers to the polymer matrix to give it the desired conductive properties.

Black and white conductive hemming film has been proven to be one of the most widely used functional fillers for plastics. In addition to providing electrical conductivity for plastic compounds, they also provide long-lasting protection against UV degradation. Carbon black is used as a medium-cost pigment to produce various shades of black in the final product. In many formulations, the masterbatch manufacturer can provide a solution in which several characteristics are combined in one product.
The choice of suitable carbon black for the production of conductive compounds is based on the desired final properties of the particular compound. It depends on the specific properties of carbon black. Including particle size, structure and purity. The selected carbon black can then be mixed with a variety of carrier resins to produce the final compound.
The requirements for effective black and white conductive hemming film compounds include:
1. Excellent dispersibility.
2. The integrity of the carbon black structure or network.
3. Consistent granularity.
4. High specific resistance
5. Conductivity
The electrical conductivity is measured by the surface resistivity (SR) of the conductive film. For a specific conductive black compound, better conductivity will allow design engineers to use the appropriate carbon black loading to achieve the required surface resistivity for the application.
The conductivity depends on:
Polymer matrix
Type of conductive black
Concentration of conductive black
The dispersion quality of the compound
Distribution of conductive black during extrusion
6. Volume conductivity
Increasing volume conductivity usually means decreasing surface resistance. The figure above illustrates the internal resistance of various substances. In order to reduce the internal resistance of polymers, it is very common to add conductive materials such as carbon black. The required amount varies depending on the desired final properties of the polymer film or molded article.
