Generally utilized additives in plastic shade matching include dispersants, lubricating substances, diffusion oils, coupling representatives, compatibilizers, and so on. Frequently come across resin ingredients include fire retardants, strengthening agents, brighteners, UV preventions, antioxidants, antibacterial agents, antistatic representatives, and so on. The most usual ones are fillers for expense decrease or physical adjustment, such as light calcium carbonate, heavy calcium carbonate, talc, mica, kaolin, silica, titanium dioxide, red mud, fly ash, diatomaceous earth, wollastonite, glass beads, barium sulfate, calcium sulfate, etc, in addition to natural fillers, such as wood flour, corn starch, and other agricultural and forestry spin-offs. Filling and strengthening products consist of glass fiber, carbon fiber, asbestos fiber, artificial natural fiber, and so on
Suppose the above additives are added to the product’s resources. In that situation, they need to be included in the material raw materials in the same percentage in the color-matching proofing so as not to create a color difference in the succeeding manufacturing.

Dispersant
Dispersant types include fat polyurea, hydroxy stearate, polyurethane, oligomeric soap, etc
At present, the commonly utilized dispersant in the industry is lubricant. Lubricants have excellent dispersibility and can also enhance the fluidity and demolding performance of plastics during molding.
Lubricants are divided into inner lubricating substances and exterior lubricating substances. Internal lubricating substances have a certain compatibility with resins, which can decrease the communication between material molecular chains, minimize melt thickness, and improve fluidity. Exterior lubes have poor compatibility with materials. They abide by the surface of molten materials to develop a lubricating molecular layer, thereby minimizing the rubbing in between materials and processing devices.
Lubricants
According to the chemical framework, they are primarily divided into hydrocarbons, metal soaps, lubricating substances that play a demolding function, fats, fatty acid amides, and esters.
Such as plastic bis ceramide (EBS)
EBS (Ethylene Bis Stearamide), also called plastic bis stearamide, is an extremely efficient internal and external lubricant and dispersant extensively utilized in the plastic handling industry. It is suitable for all polycarbonate and thermosetting plastics, consisting of yet not restricted to polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyamide (), polyester (PET/PBT), polyurethane (PU), phenolic material, epoxy resin, and so on. Here are a few of the major roles of EBS in these plastics:

Dispersion
As a dispersant, EBS can aid evenly spread fillers and pigments during plastic handling, prevent jumble, and boost the dispersion and stability of pigments and fillers. This assists boost the shade harmony and mechanical homes of the end product. As an example, in masterbatch production, EBS can guarantee that pigment particles are evenly distributed in the service provider resin to make sure that constant color is exhibited in succeeding plastic products.
Inner lubrication
In the plastic melt, EBS can decrease the friction in between particles and the shear stress of the plastic melt, thus lowering the melt thickness and making the thaw circulation smoother. This helps reduce stress during extrusion or injection molding, decreases handling temperature levels, and shortens molding cycles, while likewise reducing energy intake, improving processing effectiveness, and improving the life span of tools.
External lubrication
EBS creates a thin lubricating film on the plastic surface area, which can reduce the friction in between the plastic thaw and the metal mold, enhance demolding efficiency, and stop sticking of plastic items during molding. This not only helps to boost the surface coating of the item and lower issues but likewise streamlines the post-processing process and enhances manufacturing effectiveness.
Other functions
In addition to the above major functions, EBS can additionally be used as an antistatic representative to enhance the antistatic properties of plastic items and decrease problems such as dirt adsorption brought on by fixed power. In some applications, EBS can also enhance the weather resistance and chemical resistance of plastic items.
In the shot molding process, when dry coloring is used, surface treatment representatives such as white mineral oil and diffusion oil are normally added during mixing to play the role of adsorption, lubrication, diffusion, and demolding. When readjusting the shade, it must also be contributed to the raw products in proportion. Initially, add the surface therapy agent and tremble well, then include the color powder and shake well.
When choosing, the temperature resistance of the dispersant need to be determined according to the molding temperature level of the plastic resources. From a price point of view, in concept, if a medium and low-temperature dispersant can be utilized, a high-temperature resistant one needs to not be selected. High-temperature dispersants need to be immune to greater than 250 ° C.
