Pigment masterbatches
Description
Masterbatches for polymers mass colouring are concentrates that transform thermoplastic and thermoset polymers from colourless and opaque materials to brilliant and coloured. The craft of polymer colouring is not only a matter of knowing the basics of the colours perception optical phenomena, but also understanding the reactions that pigments and dyes can have with base resin, mineral fillers and additives as well as the material final application and the processes undertaken. There are soluble colorant substances (dyes) and insoluble substances (pigments) that can be organic or inorganic, natural or synthetic. Combinations of these types of ingredients are contained in the modern masterbatches along with other non-colouring additives. It is through this complexity that it is possible to develop strength, depth and resistance to colours.
Characteristics
Some of the masterbatch must-have characteristics required by the market are:
- High concentration for a high coverage capacity with low impact on the polymer’s properties
- Uniform distribution for high-throughput processes
- Easy dosing for process automation
- Stability at process conditions
- Stability at employment conditions
- Transparency or opacity based on request
- Possibility to create special effects such as fluorescence, opalescence, glittering etc.
- Absence of heavy metals or harmful ingredients for the manufacturing of articles in contact with food, potable water or medical devices, etc.
Processing
Among the different colouring technologies available to process polymers, MESGO Iride Colors can supply masterbatches in granules pastes, liquid and predispersed powders. In all these four cases, the dispersion of different components is obtained at high shear by using available technologies to process the polymers. Another important aspect is the colour matching, mainly obtained by preparing a countertype on customer’s request and by imitating from the reference colour table (RAL or Pantone) or transferring one colour from one material to another.
Some applications
- Color and conductive masterbatches for VMQ: HCR, LSR and RTV Coloring solutions for any silicone rubber application for extrusion, moulding and calendaring. Customized and ready to go solution in compliance with the international standard in order to achieve every customer need.
- Color and additive masterbatches for: Thermoset & Thermoplastic A wide range of masterbatch for extrusion and moulding suitable for EPDM, NBR, SBR, FKM, EVA, LDPE, PP, PVC, GPPS, ABS together with taylor made solution to better meet the request of the market. A broad range of additives masterbatch for a complete solution set.
- Color pastes in plasticizers: Many solutions for different market applications available with phthalate based plasticizers or phthalate-free.
- Additive masterbatches for VMQ: HCR Product specifically designed to modify and improve properties and performances of silicone-based compounds. A complete set of additives, from flame retardant to polymer modifier suitable for different market and application.
