Commonly utilized additives in plastic color matching include dispersants, lubricating substances, diffusion oils, coupling agents, compatibilizers, etc. Generally come across material ingredients consist of fire retardants, toughening representatives, brighteners, UV preventions, antioxidants, anti-bacterial agents, antistatic representatives, etc. The most usual ones are fillers for expense decrease or physical alteration, such as light calcium carbonate, hefty 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 agricultural and forestry spin-offs. Loading and enhancing materials include glass fiber, carbon fiber, asbestos fiber, synthetic organic fiber, etc
Suppose the above additives are contributed to the item’s raw materials. In that case, they have to be added to the material raw materials in the very same proportion in the color-matching proofing so as not to create a color distinction in the succeeding manufacturing.

Dispersant
Dispersant types consist of fat polyurea, hydroxy stearate, polyurethane, oligomeric soap, etc
At present, the commonly utilized dispersant in the market is lubricating substance. Lubes have excellent dispersibility and can also enhance the fluidness and demolding efficiency of plastics throughout molding.
Lubricating substances are divided right into internal lubes and exterior lubes. Interior lubricating substances have a specific compatibility with resins, which can decrease the communication between resin molecular chains, reduce melt thickness, and improve fluidity. External lubricating substances have poor compatibility with resins. They follow the surface of liquified materials to develop a lubricating molecular layer, therefore lowering the rubbing in between materials and handling equipment.
Lubricants
According to the chemical structure, they are mostly divided into hydrocarbons, metal soaps, lubes that play a demolding function, fatty acids, fat amides, and esters.
Such as plastic bis ceramide (EBS)
EBS (Ethylene Bis Stearamide), additionally called vinyl bis stearamide, is a very efficient internal and external lubricating substance and dispersant commonly used in the plastic processing industry. It appropriates for all polycarbonate and thermosetting plastics, including however not restricted to polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyamide (), polyester (PET/PBT), polyurethane (PU), phenolic material, epoxy resin, etc. Right here are several of the primary duties of EBS in these plastics:

Dispersion
As a dispersant, EBS can aid evenly distribute fillers and pigments during plastic handling, stay clear of jumble, and boost the dispersion and security of pigments and fillers. This assists boost the color harmony and mechanical buildings of the end product. For instance, in masterbatch production, EBS can make certain that pigment particles are equally dispersed in the service provider resin to make sure that constant shade is displayed in subsequent plastic products.
Internal lubrication
In the plastic melt, EBS can minimize the friction between molecules and the shear anxiety of the plastic thaw, therefore lowering the thaw thickness and making the melt flow smoother. This helps reduce stress during extrusion or shot molding, lowers handling temperatures, and reduces molding cycles, while additionally lowering power usage, improving handling effectiveness, and enhancing the service life of equipment.
Outside lubrication
EBS creates a slim lubricating film on the plastic surface, which can decrease the rubbing in between the plastic thaw and the metal mold, improve demolding performance, and avoid sticking of plastic items throughout molding. This not just helps to improve the surface area coating of the item and minimize defects yet additionally simplifies the post-processing process and boosts production effectiveness.
Other features
In addition to the above major functions, EBS can likewise be utilized as an antistatic agent to boost the antistatic residential or commercial properties of plastic products and reduce troubles such as dust adsorption caused by fixed power. In some applications, EBS can also enhance the weather condition resistance and chemical resistance of plastic products.
In the injection molding procedure, when completely dry tinting is made use of, surface treatment agents such as white mineral oil and diffusion oil are normally included during blending to play the duty of adsorption, lubrication, diffusion, and demolding. When changing the color, it should additionally be contributed to the raw products in proportion. Initially, add the surface treatment representative and tremble well, then add the color powder and shake well.
When selecting, the temperature level resistance of the dispersant must be identified according to the molding temperature of the plastic raw material. From a price viewpoint, in concept, if a medium and low-temperature dispersant can be made use of, a high-temperature resistant one should not be chosen. High-temperature dispersants require to be resistant to more than 250 ° C.
