Recycling with CompoundsIn the recycling sector, exceptional investors need to make the right investment that will differentiate them from their competitors by recycling with the Monomex twin screw extruder.
Calcite Use In Plastic IndustryCalcite is known as a filling material in the plastic industry and is often used by mixing (Compounding) into high proportions of plastic materials to cheapen plastic materials.
What is Compound?Mixing different materials together under pressure by melting at high temperature is used as a Compound in the plastic industry.
Masterbatch
Monomex, the great power behind masterbatch manufacturers, works in the sector to continuously ensure higher quality and more efficient production. The necessary support is provided by monomex for smart investors who want to make more profitable production. You can make better investments by discussing the chemistry of production with our expert engineer staff on masterbatch.
General processes where masterbatches are used; injection, blow molding, film, extrusion (sheet, profile), calender, rotation.
Masterbatches can be used as colorants and property changers in Polyethylene, Polypropylene, Polystyrene, ABS, EVA, engineering plastics and special compounds.
Masterbatches; Various productions are available as organic pigment masterbatches, inorganic pigment masterbatches and mineral fillers, additive masterbatches, black masterbatch, white masterbatch. Please contact us for information on how these productions are carried out and how to choose the right machine.
If we explain what Masterbatch is and give the real recipe for Masterbatch production:
Masterbatches are produced with a combination of high-performance organic and inorganic pigments and original polymer raw materials. In antisplit masterbatch production, it is the masterbatch obtained by loading a high amount of filler material into the main carrier raw material, as in normal masterbatch production. The filling materials used here are generally Calcite (CaCO3) and talc materials. It is difficult to reconcile two different materials with each other. For this reason, the choice of machine and the additives used are important factors in facilitating production, increasing the amount of filling materials loaded and product quality. Various additives are used in making antisplit masterbatch. These are PE wax, Zinc stearate, calcium stearate. Particularly the solvent in the wax should be taken into consideration and wax with a solvent with a high auto-ignition temperature should be used.
To give an example formulation:
- 25% LLDPE (50MFI)
- 70% Calcite (CaCO3)
- 2.5% PE Wax
- 1.5% Zinc Stearate
- 1% Optical Additive
In all formulations, the fluidity of the masterbatch must be higher than the fluidity of the raw material to be dyed. The masterbatch production process is divided into two parts: Mono and tailor made. In mono production, primary colors are used. In tailor made, that is, color matching, colors are mixed and production is made according to the desired color code.
Three methods in masterbatch production
- Pre- mix, most widely spread production process, a premix consisting of polymer, pigment and dispersion additives is fed to the extruder. Normally, these premixes are produced in batches in a previous mixing step.
- Great importance must be given to this premix process. If a mistake happens here, unfortunately, oftentimes it is very difficult to make corrections during the extrusion step. Due to the usage of volumetric feeders, there is a high operational reliability, handling is quite uncomplicated, and the process is very popular as well as low priced.
2. Split-feed version of masterbatch production, the polymer is plastified first. Then the other formulation components (pigments, fillers and if needed dispersion aids) are added via one or two side stuffers (hot melt extrusion).
Feeding is done via separate gravimetric feeders. The handling of the formulation via the extruder or feed control is relatively uncomplicated and does not need elaborate premixing. This makes big scale masterbatch production much easier.
3. Custom Colouring uses an exact mixture of standard colours (monobatches) to produce the required colour match.
Via a multi-component gravimetric feed system (generally 5 to 8 components) and predefined standard colours, the colour required by the customer is produced. The setup of the extrusion line is similar to the premix system.
We can offer the perfect machine configuration for your range of masterbatch formulations, Whether premix or split-feed or color-matching process, with our twin screw extruder.
