black pp granules is a partially crystalline thermoplastic polymer, which is obtained from the polymerization of propylene (or propane).
This is the mosted use for packaging our everyday products. Since it is considered the most environmentally friendly plastic and the most recommended for being in contact with food and cooking utensils.
Granules are the result of the plastic recycling process. By recovering plastic waste, we subject it to a rigorous process to be able to turn it into small plastic particles. Thanks to this we obtain different categories of granules such as Polypropylene Granules of Color or Black (PP) by injection.
Features of black pp granules
- Low density
- Easy to process
- Heat resistance
- Chemical resistance
- Precise melting point
- Thermal stability
There are basically two methods for obtaining color parts, injection molded. The simplest is to mix dye pellets (master mix) in a batch of pellets (see Figure 2). When the pellets are heated and compressed for injection into the mold. The base material and the dyestuff pellets melt and mix before being injected into the mold.
Polypropylene (PP) is
- completely waterproof
- resistant to corrosion
- resistant to high temperatures
- and sudden changes in temperature.
Despite their extreme diversity of appearances and sizes, injection molded parts all begin to exist in the same form. Small plastic pellets. The basic colors of these granules vary somewhat depending on the material, but all are on a monochromatic scale ranging from transparent and various shades of natural to black (see Figure 1). Transforming these small, dull granules into a rainbow of colors as they exit the molding press requires the addition of a colorant: a process that can be very simple or very complicated depending on the case. It will be more complex if you are very demanding about your color.
