Black Masterbatch
High Concentrate Black Masterbatch
- Black Masterbatch is a concentrated mixture of high-purity carbon black pigments uniformly dispersed in a polymer carrier resin, such as Polyethylene (PE) or Polypropylene (PP). It is primarily used for efficiently coloring a wide range of plastic products through processes like injection molding, blow molding, and film extrusion, serving industries from packaging and automotive to agriculture and construction.
- Excellent Dispersion: Provides a smooth, consistent black color without specks or streaks.
- Superior Color Strength: Offers intense blackness and hiding power at low addition rates.
- Outstanding Thermal Stability: Withstands high processing temperatures without degrading.
- Good Compatibility: Ensides seamlessly with the base polymer matrix (e.g., PE, PP, PC, ABS,PS etc).
- High Weathering & UV Resistance: Ensures long-term color fastness and product durability outdoors.

Black Masterbatch Composition
- Black masterbatch is a precision-engineered concentrate composed of three essential components, each critical to the final performance and quality
- High-Purity Carbon Black Pigment is the primary coloring agent. We select specific grades of carbon black based on the target application. For instance, a high-color furnace black provides jetness for premium packaging, while a larger particle size channel black offers superior UV resistance for agricultural films. The purity and particle size distribution are strictly controlled to ensure rich, consistent color depth and desired functional properties like conductivity or weather resistance.
- Polymer Carrier Resin acts as the delivery vehicle for the pigment. The carrier resin is specifically chosen to be chemically compatible with the base polymer of the end product (e.g., LDPE for polyethylene films, Homo-PP for polypropylene containers). This compatibility is vital for ensuring seamless integration, excellent dispersion, and maintaining the mechanical properties of the final plastic article.
- Dispersing Agents coat the pigment particles, reducing their surface tension to prevent agglomeration and ensure a speck-free, homogeneous dispersion within the polymer melt.
- Thermal Stabilizers protect both the pigment and the polymer from degrading at high processing temperatures, preventing yellowing or loss of properties.
- Lubricants improve the flow characteristics of the melt, reducing viscosity for easier processing and higher production output.
Wide Application of Black Masterbatch
Blown Film
This involves extruding a molten polymer tube through a circular die, which is then inflated by air into a thin, continuous bubble, cooled, and collapsed into lay-flat film. The process requires exceptional pigment dispersion to prevent gel formation and ensure uniform optical density and mechanical strength across the film web.
- High-strength trash bags, carrier bags, shrink films, and flexible food packaging (often requiring food-contact compliant grades).
- Black mulch films (for weed suppression and soil warming), silage stretch films, and greenhouse covers.
- Protective packaging films, geomembranes for landfill liners and pond capping.
Injection Molding
This high-speed, high-pressure process involves injecting molten plastic into a closed mold cavity. The material must fill the mold completely before solidifying into the desired shape. Cycle time and surface finish are critical. Low viscosity ensures easy flow into intricate mold details. Prevents thermal degradation during potential residence time in the heating barrel.
- Interior automotive components (dashboards, console panels), exterior parts (bumpers, mirror housings), and under-the-hood components.
- Housings for appliances, power tools, televisions, and computers.
- Pallets, crates, containers, toys, and furniture components.
Extrusion Product
This continuous process involves forcing molten plastic through a die to create long products with a fixed cross-sectional profile, such as pipes, sheets, or window frames. Consistency over long production runs is paramount. Critical UV resistance for outdoor applications to prevent fading and maintain material integrity. Protects the polymer from environmental stress cracking.
- Pressure pipes for potable water, sewer and drainage pipes, gas distribution pipes.
- Window and door frames, fencing, decking, and siding.
- Corrugated roofing sheets, industrial sheets, and thermoforming substrates.
Blow Molding
A parison (a hollow tube of molten plastic) is extruded downward into a mold. The mold closes, and air is blown into the parison, inflating it to take the shape of the mold cavity. This is used for creating hollow objects. The parison must have sufficient strength to hold its shape without sagging before inflation. Prevents the accumulation of pigment or additives on the mold surface, which would mar the product's appearance.
- Bottles for cosmetics, household chemicals, and automotive fluids (e.g., motor oil bottles).
- Large containers, drums, and automotive fuel tanks.
Fiber Spinning
Polymer is melted, extruded through a spinneret (a die with numerous tiny holes), and the resulting continuous filaments are drawn (stretched) to orient the polymer molecules, enhancing tensile strength. This is a highly demanding process. Essential to prevent nozzle clogging and fiber breakage during high-speed spinning. Any agglomerates will cause filament rupture, leading to production downtime.
- Clothing, sportswear, and home textiles.
- Geotextiles for road construction, filtration fabrics, and non-wovens for hygiene products.
- Bulked Continuous Filament yarn for carpeting.
Cast Molding
Rotomolding is a unique high-temperature, low-pressure process used to create large, hollow, seamless products. Fine plastic powder (or liquid) is placed inside a hollow mold. The mold is then heated and rotated biaxially (on two axes), causing the material to gradually melt and coat the interior walls of the mold cavity. The process places very specific demands on colorants.
- hemical storage tanks, water tanks, septic tanks, and agricultural containers.
- Bulk shipping containers (IBCs), pallets, and large industrial bins.
- Ducts, fuel tanks, and other large hollow parts.
