Our PE-based high concentration black masterbatch is precisely formulated and produced with high-purity carbon black raw materials and mature production technology, greatly superior to ordinary black masterbatches in market in terms of blackness, tinting strength and covering power. It can perfectly cover the original background color of plastic substrates, endowing finished plastic products with pure, uniform and glossy black appearance without gray tone or color deviation. The product boasts excellent comprehensive stability, including outstanding weather resistance and high-temperature resistance up to 260°C, which enables it to adapt to various high-temperature processing environments of film blowing, injection molding and extrusion molding. It will not decompose, fade or produce harmful substances during processing, ensuring stable molding quality of plastic products.
With superb molecular dispersion technology, this PE black masterbatch achieves uniform pigment distribution inside the carrier, avoiding pigment precipitation, agglomeration and floating problems in the production process. The regular free-flowing pellet design ensures smooth automatic feeding and even mixing with PE resin, effectively improving production efficiency and reducing product defect rates. Our factory implements standardized batch production management, with zero obvious color difference between different batches, completely solving the problem of color instability in continuous large-scale production for B-end industrial customers.
In addition, this eco-friendly black masterbatch has stable chemical properties and will not damage the inherent mechanical properties of PE plastics, such as tensile strength, toughness and impact resistance. With high pigment concentration and strong tinting power, it requires only a low addition dosage of 1%–5% to achieve ideal coloring effects, significantly reducing customers’ overall production costs. It covers a wide range of application scenarios, including food-contact packaging plastics, daily consumer plastic products, industrial plastic accessories, PE pipe extrusion materials and blown film products, meeting the diversified processing needs of various medium and high-end plastic products.
| Carrier Material | PE (Polyethylene) |
| Pigment Concentration | High concentration |
| Appearance | Uniform black free-flowing solid pellets |
| Heat Resistance | ≥260°C |
| Dispersion Performance | Excellent, no agglomeration, no precipitation |
| Recommended Addition Ratio | 1%–5%, adjustable according to target blackness and product specifications |
To ensure optimal coloring effect, evenly premix the PE black masterbatch with pure PE resin before formal processing. The product is slightly hygroscopic; please keep the processing and storage environment dry and ventilated. Seal and store the unused masterbatch in a cool, dry place away from moisture and dust pollution to maintain stable dispersion and coloring performance for subsequent use.
The recommended addition ratio is 1% to 5%, which can be adjusted depending on your target blackness requirement and specific product specifications.
It is suitable for multiple high-temperature processing environments, including film blowing, injection molding, and PE pipe extrusion molding.
This product features excellent thermal stability with a high-temperature resistance of up to ≥260°C without decomposing or fading during processing.
No, it has stable chemical properties and does not compromise the inherent mechanical properties of PE plastics, such as tensile strength, toughness, or impact resistance.
Since the masterbatch is slightly hygroscopic, unused products should be sealed and stored in a cool, dry, and ventilated place away from moisture and dust pollution.
