Commonly used ingredients in plastic color matching include dispersants, lubes, diffusion oils, combining agents, compatibilizers, and so on. Generally encountered resin ingredients consist of flame resistants, toughening agents, brighteners, UV inhibitors, antioxidants, antibacterial representatives, antistatic agents, etc. The most usual 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 planet, wollastonite, glass beads, barium sulfate, calcium sulfate, and so on, in addition to organic fillers, such as wood flour, corn starch, and various other agricultural and forestry byproducts. Filling and strengthening materials consist of glass fiber, carbon fiber, asbestos fiber, synthetic natural fiber, and so on
Mean the above additives are included in the product’s raw materials. Because situation, they should be added to the resin basic materials in the same proportion in the color-matching proofing so as not to generate a shade distinction in the subsequent manufacturing.

Dispersant
Dispersant types consist of fat polyurea, hydroxy stearate, polyurethane, oligomeric soap, etc
Presently, the commonly used dispersant in the sector is lube. Lubes have good dispersibility and can additionally improve the fluidity and demolding performance of plastics throughout molding.
Lubricating substances are separated right into interior lubes and outside lubricants. Internal lubricating substances have a certain compatibility with materials, which can lower the communication in between material molecular chains, decrease thaw thickness, and boost fluidness. Outside lubricating substances have poor compatibility with materials. They adhere to the surface area of liquified materials to develop a lubricating molecular layer, therefore reducing the friction in between resins and processing tools.
Lubricants
According to the chemical structure, they are primarily divided into hydrocarbons, metal soaps, lubricating substances that play a demolding function, fatty acids, fatty acid amides, and esters.
Such as vinyl bis ceramide (EBS)
EBS (Ethylene Bis Stearamide), also known as vinyl bis stearamide, is a highly reliable inner and exterior lubricant and dispersant commonly made use of in the plastic handling sector. It is suitable for all thermoplastic and thermosetting plastics, including however not limited to polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyamide (), polyester (PET/PBT), polyurethane (PU), phenolic material, epoxy resin, and so on. Right here are some of the main functions of EBS in these plastics:

Diffusion
As a dispersant, EBS can help equally spread fillers and pigments throughout plastic handling, avoid load, and improve the diffusion and stability of pigments and fillers. This assists improve the color harmony and mechanical buildings of the final product. For instance, in masterbatch production, EBS can make sure that pigment particles are equally distributed in the carrier resin to ensure that regular color is displayed in succeeding plastic products.
Interior lubrication
In the plastic thaw, EBS can decrease the friction between molecules and the shear stress and anxiety of the plastic melt, thus reducing the thaw viscosity and making the thaw flow smoother. This helps reduce stress during extrusion or injection molding, decreases processing temperature levels, and shortens molding cycles, while also reducing power intake, improving processing effectiveness, and improving the service life of equipment.
Outside lubrication
EBS develops a thin lubricating film on the plastic surface area, which can decrease the rubbing in between the plastic melt and the steel mold, improve demolding efficiency, and stop sticking of plastic products throughout molding. This not only aids to improve the surface area coating of the item and minimize defects but additionally simplifies the post-processing process and improves production efficiency.
Other functions
In addition to the above main functions, EBS can also be used as an antistatic representative to boost the antistatic homes of plastic items and decrease issues such as dirt adsorption brought on by static power. In some applications, EBS can additionally improve the weather condition resistance and chemical resistance of plastic items.
In the injection molding procedure, when dry coloring is used, surface treatment representatives such as white mineral oil and diffusion oil are usually included throughout mixing to play the function of adsorption, lubrication, diffusion, and demolding. When readjusting the color, it should additionally be added to the raw materials in proportion. First, add the surface treatment agent and drink well, after that add the shade powder and drink well.
When selecting, the temperature resistance of the dispersant ought to be established according to the molding temperature level of the plastic raw material. From a price point of view, in concept, if a medium and low-temperature dispersant can be used, a high-temperature resistant one needs to not be selected. High-temperature dispersants need to be immune to greater than 250 ° C.
