Titanium oxide PNR-616
TiO2 PNR-616 has fine particle size and low oil absorption ability which makes it suitable for plastic extrusion process, such as polyolefin, PVC rolling film, ABS, PS, tube and emulsion paints.
Easy Colour pigment (ECP)
Easy Colour is the tradename for our highly concentrated single pigment dispersion. The single pigment dispersion contains pigment concentration around 60% in a low molecular weight polyethylene. The product is supplied as a fine powder with particle size approximately 0.20 – 0.30 mm. Easy Colour is suitable for PE, PP, EVA, PS, POM, PET and many more resin. It is used in fibre, film, injection molding and blow molding applications.
Nano pigments
Solvent dyestuffs
Most suitable for various plastic materials coloring, with greater color strength, better fastness to heat, light, acid and alkali. This range is generally used in coloring domestic plastic materials, cop tube materials, fat dyeing, lacquers, inks and master batches dyeing. Some of them are suitable for dyeing chemicals fibre such as dacron, nylon and cellulose acetate fibre.
The dye is dissolved in plastic in molecular-distribution. Before molding or preplasticizing, add dyes into plastic materials in proportion and stir thoroughly. The shade can be adjusted in demand.

Near Infrared Reflective Black Masterbatch
The most common black colorant used in plastics has been carbon black, as it is low in cost and has high tint strength. The black colour provides a contrasting background and allows the colours in the food to stand out. However, black plastics that are coloured with carbon black colourants present a problem for NIR detectors as carbon black strongly absorbs infrared radiation as well as visible light, so the NIR light is not reflected into the detectors. This means that the black items remain undetected and end up in the residual fraction from the sorting processes and are disposed to landfill.
The alternative black pigments should reflect in the NIR spectrum but absorb in the visible spectrum.
Advantages:
- Recovery of black plastic packaging to be used in new application instead of virgin plastic
- Increase recycling revenue
- Reduce carbon emissions and landfill volumes
Features:
- The final product has the similar black colour and shade as the ones made with carbon black
- Can be produced in industrial scale
- Low risk of colour migration
- Good colour stability
