What are the advantages of automotive coatings treated by plasma surface treatment equipment:
For some brands of car interiors, for the sake of beauty, comfort, sound insulation and noise prevention, they often choose genuine leather or artificial leather for surface coating. There are high requirements for quality, durability and environmental protection before pretreatment and coating, and it is an inevitable trend for plasma surface treatment equipment to replace the flame method.
Due to the wide variety of automotive interior parts, different shapes and different materials, only one type of plastic includes ABS, PC, PA, PVC, TPO, PET, PP, EPDM, etc. As consumers are concerned about health and safety , With the improvement of comfort requirements, the proportion of PP materials used in automotive interior parts is increasing, such as instrument panels, door panels, central control seats, luggage boxes, etc. Below, let’s take PP as an example. What are the advantages of using plasma surface treatment equipment before coating automotive interior parts? What is special about the plasma surface treatment process?

PP, or polypropylene, is a thermoplastic resin polymerized from propylene. It has high crystallinity and regular structure. It is a non-polar polymer with a weak boundary layer on the surface of the material. The introduction of impurities during the polymerization process, the low-molecular components of the polymer itself, the various additives added, and the contaminants introduced during the storage and transportation process, etc., will cause the existence of a weak boundary layer, thereby greatly reducing the bonding strength of the joint. Therefore, special surface treatment must be carried out before the car interior coating.
The pretreatment of ordinary polypropylene material interior parts is flame burning. Due to the high flame temperature, it is easy to cause color change and deformation, and the efficiency is low, and there are hidden safety hazards. The appearance of plasma surface treatment technology has changed this situation. .
Advantages of using plasma surface treatment equipment technology before covering polypropylene interior parts:
1. The shape, material, and size of the processed material are not restricted, so that the surface of the material can be uniformly cleaned and activated.
2. The plasma surface treatment technology is reliable, the product consistency is good, and the parts will not be thermally deformed or degraded.
3. This product is dry cleaning and does not contain any residual substances, which can reduce the VOC content of interior parts.
4. There are no chemical consumables and it is more environmentally friendly.
5. The safety during operation will not affect the health of the operator.
