Frequently utilized additives in plastic color matching include dispersants, lubricants, diffusion oils, coupling agents, compatibilizers, etc. Typically experienced resin ingredients include flame retardants, toughening agents, brighteners, UV preventions, anti-oxidants, anti-bacterial representatives, antistatic agents, etc. One of the most common ones are fillers for expense decrease or physical alteration, such as light calcium carbonate, heavy calcium carbonate, talc, mica, kaolin, silica, titanium dioxide, red mud, fly ash, diatomaceous earth, wollastonite, glass grains, barium sulfate, calcium sulfate, and so on, in addition to natural fillers, such as wood flour, corn starch, and various other farming and forestry byproducts. Filling and strengthening products include glass fiber, carbon fiber, asbestos fiber, artificial natural fiber, etc
Suppose the above additives are included in the item’s resources. In that case, they need to be contributed to the resin raw materials in the same proportion in the color-matching proofing so as not to generate a color difference in the subsequent production.

Dispersant
Dispersant types include fat polyurea, hydroxy stearate, polyurethane, oligomeric soap, and so on
Today, the frequently used dispersant in the industry is lubricant. Lubricants have excellent dispersibility and can likewise improve the fluidity and demolding performance of plastics during molding.
Lubricating substances are separated into interior lubricants and external lubes. Interior lubes have a specific compatibility with materials, which can lower the communication between resin molecular chains, minimize thaw viscosity, and boost fluidity. Outside lubricants have bad compatibility with resins. They comply with the surface of molten materials to develop a lubricating molecular layer, therefore lowering the rubbing in between materials and handling tools.
Lubricants
According to the chemical structure, they are mostly split right into hydrocarbons, metal soaps, lubricating substances that play a demolding role, fats, fatty acid amides, and esters.
Such as plastic bis ceramide (EBS)
EBS (Ethylene Bis Stearamide), additionally called vinyl bis stearamide, is a highly efficient interior and external lubricating substance and dispersant widely used in the plastic handling sector. It appropriates for all polycarbonate and thermosetting plastics, consisting of yet not limited to polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (COMPUTER), polyamide (PA), polyester (PET/PBT), polyurethane (PU), phenolic material, epoxy resin, etc. Below are several of the main roles of EBS in these plastics:

Diffusion
As a dispersant, EBS can assist uniformly disperse fillers and pigments throughout plastic handling, prevent load, and boost the diffusion and stability of pigments and fillers. This helps boost the color harmony and mechanical properties of the final product. For instance, in masterbatch production, EBS can ensure that pigment bits are equally dispersed in the carrier material to ensure that constant shade is exhibited in succeeding plastic items.
Inner lubrication
In the plastic thaw, EBS can decrease the friction between molecules and the shear stress and anxiety of the plastic thaw, therefore lowering the thaw thickness and making the thaw circulation smoother. This helps reduce pressure throughout extrusion or injection molding, decreases processing temperature levels, and reduces molding cycles, while also lowering power consumption, enhancing handling efficiency, and boosting the service life of devices.
Exterior lubrication
EBS creates a slim lubricating film on the plastic surface area, which can lower the friction in between the plastic melt and the steel mold, enhance demolding performance, and prevent sticking of plastic products throughout molding. This not only assists to enhance the surface finish of the product and decrease issues yet also simplifies the post-processing process and enhances production efficiency.
Various other features
Along with the above main functions, EBS can also be used as an antistatic representative to enhance the antistatic properties of plastic products and decrease issues such as dust adsorption triggered by fixed electricity. In some applications, EBS can likewise boost the weather condition resistance and chemical resistance of plastic products.
In the shot molding procedure, when completely dry coloring is used, surface area treatment agents such as white mineral oil and diffusion oil are usually included during mixing to play the role of adsorption, lubrication, diffusion, and demolding. When changing the shade, it must likewise be included in the raw products symmetrical. First, add the surface area treatment representative and drink well, after that include the color powder and tremble well.
When selecting, the temperature resistance of the dispersant must be determined according to the molding temperature of the plastic resources. From a cost perspective, in principle, if a medium and low-temperature dispersant can be used, a high-temperature resistant one should not be selected. High-temperature dispersants need to be immune to greater than 250 ° C.
