What are the main raw materials for the production of reinforced wax-based carbon strips?

The main raw materials for the production of reinforced wax-based carbon strips mainly include the following aspects:

1. Polyester Film (PET)

Function: Mylar is the base material of the carbon belt, as the base material of the carbon belt, carrying the ink coating and other functional layers.

Importance: The quality of polyester film directly affects the physical properties, printing effect and service life of the carbon strip.

Remarks: According to the report of Every channel network, some enterprises producing carbon belt, such as digital World, the raw materials for the production of carbon belt products are mainly polyester film, and polyester film accounts for more than 50% of the raw material cost.

2. Wax materials

Type: The wax-based carbon strip contains a high percentage of wax-based raw materials, and these wax-based materials determine the melting point of the carbon strip, which affects the energy level required for printing. Common wax materials include carnauba wax, fully refined wax, etc.

Function: The wax material gives the carbon strip good printing performance and adhesion, making the printed text and images clear and bright.

3. Resin material

Type: One of the main differences between the reinforced wax-based carbon strip and the ordinary wax-based carbon strip is that it contains nearly 20% resin composition. These resin materials may include vinyl resins, petroleum resins, polypropylene resins, etc.

Action: The addition of resin improves the scratch resistance, wear resistance and chemical corrosion resistance of the carbon strip, making the enhanced wax-based carbon strip perform well in a variety of application environments.

Step 4: Paint

Function: pigment is one of the important components of the carbon strip ink coating, which determines the color and brightness of the printed text and image.

Type: Depending on the specific needs, the type of pigment may vary, but it usually needs to have good dispersion and stability.

5. Dispersants and other additives

Role: Dispersant plays a key role in the preparation of ink coating, which helps the solid particles such as pigments and resins to disperse evenly in the solvent, forming a stable ink system. In addition, other additives may be added to improve the performance of the carbon strip, such as anti-stick agents, leveling agents, etc.

Note: It should be noted that with the advancement of technology and optimization of formulations, dispersants may no longer be required in the preparation of some new enhanced wax-based carbon strips, but the uniform dispersion of ink coatings can be achieved by adjusting the reasonable composition of resins and waxes.

In summary, the main raw materials for the production of wax-based carbon strips include polyester film, wax materials, resin materials, pigments, dispersants and other additives. The selection and proportion of these raw materials directly affect the performance and quality of the carbon strip.
