Commonly used ingredients in plastic color matching include dispersants, lubes, diffusion oils, combining representatives, compatibilizers, and so on. Generally encountered resin ingredients include flame retardants, toughening agents, brighteners, UV preventions, anti-oxidants, antibacterial representatives, antistatic agents, 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 grains, barium sulfate, calcium sulfate, etc, as well as natural fillers, such as wood flour, corn starch, and various other agricultural and forestry spin-offs. Filling and strengthening materials consist of glass fiber, carbon fiber, asbestos fiber, artificial natural fiber, and so on
Intend the above ingredients are added to the product’s raw materials. In that situation, they have to be contributed to the resin resources in the very same percentage in the color-matching proofing so as not to produce a shade distinction in the succeeding manufacturing.

Dispersant
Dispersant types include fat polyurea, hydroxy stearate, polyurethane, oligomeric soap, and so on
At present, the typically utilized dispersant in the industry is lubricating substance. Lubricating substances have good dispersibility and can additionally enhance the fluidity and demolding efficiency of plastics throughout molding.
Lubricating substances are divided into interior lubricants and external lubricants. Inner lubricants have a specific compatibility with materials, which can lower the cohesion between resin molecular chains, lower thaw viscosity, and enhance fluidness. Outside lubes have poor compatibility with resins. They stick to the surface of liquified materials to form a lubricating molecular layer, consequently minimizing the friction between materials and processing devices.
Lubricants
According to the chemical framework, they are mainly divided into hydrocarbons, metal soaps, lubricating substances that play a demolding function, fats, fat amides, and esters.
Such as plastic bis ceramide (EBS)
EBS (Ethylene Bis Stearamide), also known as vinyl bis stearamide, is a very reliable inner and exterior lube and dispersant widely used in the plastic handling industry. It is suitable for all polycarbonate and thermosetting plastics, consisting of however not limited to polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (COMPUTER), polyamide (), polyester (PET/PBT), polyurethane (PU), phenolic resin, epoxy resin, etc. Below are some of the main functions of EBS in these plastics:

Diffusion
As a dispersant, EBS can aid evenly spread fillers and pigments throughout plastic processing, avoid jumble, and enhance the diffusion and security of pigments and fillers. This helps boost the color harmony and mechanical residential or commercial properties of the end product. For example, in masterbatch production, EBS can guarantee that pigment particles are evenly dispersed in the carrier material to ensure that constant shade is shown in subsequent plastic products.
Internal lubrication
In the plastic melt, EBS can minimize the rubbing in between particles and the shear anxiety of the plastic melt, thereby decreasing the thaw viscosity and making the melt flow smoother. This helps reduce stress during extrusion or injection molding, decreases processing temperatures, and reduces molding cycles, while additionally lowering energy usage, improving handling effectiveness, and improving the life span of devices.
Outside lubrication
EBS forms a slim lubricating film on the plastic surface area, which can lower the rubbing in between the plastic melt and the steel mold and mildew, improve demolding performance, and prevent sticking of plastic items throughout molding. This not only helps to enhance the surface finish of the product and reduce defects but likewise streamlines the post-processing process and boosts production effectiveness.
Other features
Along with the above primary functions, EBS can also be made use of as an antistatic representative to improve the antistatic homes of plastic items and reduce troubles such as dirt adsorption caused by static power. In some applications, EBS can also boost the weather condition resistance and chemical resistance of plastic items.
In the shot molding procedure, when dry tinting is utilized, surface therapy representatives such as white mineral oil and diffusion oil are normally added during mixing to play the duty of adsorption, lubrication, diffusion, and demolding. When readjusting the color, it needs to also be contributed to the raw materials in proportion. First, add the surface treatment agent and shake well, then include the shade powder and tremble well.
When picking, the temperature level resistance of the dispersant should be determined according to the molding temperature level of the plastic resources. From a cost point of view, in principle, if a medium and low-temperature dispersant can be utilized, a high-temperature resistant one must not be picked. High-temperature dispersants require to be immune to greater than 250 ° C.
