Color Masterbatch, also known as a color seed, is a new type of special coloring agent for polymer materials, also known as Pigment Preparation. It consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate obtained by uniformly attaching an extraordinary amount of pigment or dye to the resin, which can be called Pigment Concentration, so its coloring power is higher than that of the pigment itself.

Color Masterbatch is widely used in the coloring of various plastic products, such as injection molding, blow molding, extrusion, calendering, and other processing techniques. Including plastic packaging, building materials, electronic and electrical appliances, auto parts, household goods, and many other industries. In short, a masterbatch is a convenient, stable, and good color effect plastic coloring material, widely used in the production of plastic products to meet the needs of different colors and effects. However, during the processing of color masterbatches, problems such as poor dispersion, poor solute fluidity, and poor surface quality usually occur easily:

Poor dispersion: Pigments or fillers in the color masterbatch may agglomerate during processing, resulting in poor dispersion. This can affect the homogeneity and stability of the color masterbatch.

Poor melt fluidity: the addition of certain pigments or fillers can reduce the fluidity of the polymer melt, leading to problems such as clogging and uneven extrusion during processing.

Poor surface quality: The surface of the color masterbatch may have defects such as air holes, corners, scratches, etc., which affect the appearance quality of the final product.

To solve the problems of color Masterbatch in the process, different additives are usually added in the preparation of color masterbatches, and the commonly used additives include dispersants, lubricants, stabilizers, antistatic agents, flame retardants and anti-UV agents, and so on. Each of these additives has different advantages and disadvantages.

Stabilizers: commonly used stabilizers include light stabilizers, oxidation stabilizers, heat stabilizers, and so on. The main advantage of stabilizers is that they can improve the weather resistance and oxidation resistance of color masterbatches, and prevent pigments or dyes from fading, decomposing, or deteriorating. However, excessive use of stabilizers will lead to a decline in the physical properties of color masterbatches and even adverse reactions.

Dispersants: commonly used dispersants are polyvinyl alcohol, polyethylene glycol, polycarboxylic acid, silicone-based additives, etc. Here we recommend SILIKE hyperdispersant: SILIKE SILIMER6200, SILIKE SILIMER6200 can effectively improve the uniformity and stability of the color of the masterbatch, and reduce the problem of pigment agglomeration.

Processing aids: Processing aids include lubricants (calcium stearate, zinc stearate, linoleic acid amide, etc.), flow improvers, PPA processing aids, etc. Among them, the traditional fluoropolymer PPA aids have been widely used for a long time, but due to their structure with strong polarity and very low surface energy, it is less compatible with polyolefin resin and prone to precipitation in the mouth of the mold, and fluoropolymer PPA aids are prone to be decomposed into small molecules of fluorine compounds at high temperatures, which is harmful to the human body and environment.

To improve the above difficulties, SILIKE has developed a fluorine-free PPA processing aid, SILIKE SILIMER fluorine-free PPA series is the combination of polysiloxane chain segment and polar groups, perfect integration of the excellent performance of the two, which can provide excellent lubrication processing effect, reduce torque, enhance melt flow, etc. It can effectively reduce the adhesion effect of polyolefin resin on metal parts, reduce mold accumulation, and improve melt rupture.

The main roles of SILIKE SILIMER fluoride-free PPA in color masterbatch processing include:

Improved dispersion:  SILIKE PFAS-free Polymer Processing Aids SILIMER 5090

can interact with polymer molecular chains to evenly disperse pigments or fillers in the polymer matrix, thereby improving the dispersion of the color masterbatch.

Improve melt flow: SILIKE PFAS-free Polymer Processing Aids SILIMER 5090 can reduce the melt viscosity of the polymer, improve the flow of the melt, improve the internal and external lubrication properties, make the color masterbatch easier to extrude during processing, and effectively increase the extrusion speed.

Improve surface quality: SILIKE PFAS-free Polymer Processing Aids SILIMER 5090 effectively eliminates melt cracking, improves surface quality, and enhances the finished product’s gloss and texture.

Increase production efficiency: The SILIKE PFAS-free Polymer Processing Aids SILIMER 5090 can extend equipment cleaning cycles, reduce downtime, and greatly improve production efficiency to achieve a lower overall cost.

The action principle of SILIKE SILIMER fluoride-free PPA and fluoride-containing PPA have similarities, so in industrial production, fluoride-free PPA can be completely replaced with fluoride-containing PPA. Since SILIKE SILIMER fluoride-free PPA series does not contain fluorine, is harmless to the human body, and meets the requirements of the EU ban on fluorine, it is also environmentally safe while improving the output and product volume, and is the only alternative to fluoridated polymer PPA additives.

It is worth mentioning that: SILIKE SILIMER fluoride-free PPA masterbatch needs to control the additional amount during use, different additives may affect each other, so it is necessary to carry out formula tuning and test verification to ensure the best color masterbatch or other product performance, so it is recommended: If you have the above problems, you can contact us to take samples, and test and deploy. SILIKE SILIMER fluoride-free PPA masterbatch can be used in a wide range of fields, not only for color masterbatches but also for films, pipes, plates, metallocene, etc. If you are looking for fluoropolymers, and PFAS-containing Polymer Processing Aids alternative, welcome to contact SILIKE!
