The Black Masterbatch 2050 is a purpose-built colorant solution engineered specifically for the polyolefin pipe and tubing industry. Recognizing the critical need for cost-efficiency in large-scale infrastructure projects, this model utilizes a scientifically balanced formulation of 25% Carbon Black and 43% Filler ($CaCO_3$) within a recycled carrier matrix.
Designed for the rigorous demands of extrusion, Model 2050 excels in manufacturing Water Supply Pipes, Agricultural Irrigation Systems, and Corrugated Bellows. It guarantees that the final pipe product retains its essential "toughness" and flexibility while providing a uniform, jet-black finish that is resistant to UV degradation and environmental stress cracking.

The core challenge in pipe extrusion is maintaining the mechanical integrity of the pipe wall while ensuring uniform color. The 2050 overcomes this through advanced rheological engineering:
Our formulation incorporates a specific grade of Low-Molecular-Weight Polyethylene Wax. In the extrusion barrel, this wax acts as a processing aid that significantly outperforms standard carriers.
Viscosity Reduction: The wax lowers the viscosity of the masterbatch melt, ensuring it flows more easily than the carrier resin. This prevents the "drag" that often causes flow marks.
Shear Force Activation: Under the high shear force of the screw, the wax facilitates the breakdown of carbon black agglomerates into micro-particles. This results in improved dispersion, eliminating weak points in the pipe wall that could lead to bursts under pressure.
Processing temperatures in pipe extrusion can be volatile. The 2050 is formulated with high-thermal-stability additives that prevent the carbon black from degrading or "browning" at temperatures up to 280°C. This ensures consistent color quality even during long production runs or when using regrind material.
At YHM Masterbatches, we understand that pipe failure is not an option. Although the 2050 uses a recycled carrier to optimize cost, we subject it to rigorous Quality Control (QC) protocols:
Melt Flow Index (MFI) Testing: To ensure lot-to-lot consistency.
Ash Content Analysis: To verify the precise 43% filler ratio.
Dispersion Testing: Film blowing tests are conducted to check for un-dispersed aggregates.

Crucially, the 2050 is designed to "sit" within the polyolefin matrix without disrupting the polymer chains. This ensures that the hoop stress resistance and tensile strength of the pipe—critical for passing pressure tests—remain within industry standards.
Superior Hiding Power: Despite the economical filler content, the high-grade carbon black ensures complete opacity, effectively blocking sunlight to prevent algae growth inside water pipes.
Smooth Surface Finish: The specialized wax additives ensure a glossy, smooth exterior and interior pipe surface, reducing friction loss for fluid transport.
Corrosion & Weather Resistance: Engineered for underground and outdoor use, the masterbatch enhances the pipe's resistance to soil acidity, moisture, and long-term UV exposure.
Cost-Effective Sustainability: By utilizing a high-quality recycled PE/PP carrier, the 2050 helps manufacturers lower raw material costs while contributing to circular economy goals.

The Black Masterbatch 2050 is the industry standard for non-pressure and low-pressure pipe applications:
Requirement: Pipes must withstand constant UV exposure and varying water pressures without becoming brittle.
Solution: The 2050 reinforces the PE resin’s natural flexibility, preventing cracking during bending or installation in rough terrain.
Requirement: Long-term corrosion resistance against soil chemicals and moisture.
Solution: The carbon black creates a barrier against environmental degradation, extending the service life of buried drainage systems.
Requirement: High melt strength to form the corrugated structure without tearing.
Solution: The optimized flowability of the 2050 ensures the complex ribs of the bellows are fully filled and structurally sound.
To achieve optimal results with the 2050 in a Single Screw or Twin Screw Extruder:
Feeding: The masterbatch granules are uniform (2*3mm) and can be fed via volumetric or gravimetric dosers.
Mixing: For standard pipe extrusion, a ratio of 2% to 4% is recommended. Ensure the masterbatch is tumble-mixed thoroughly if not using a dosing unit to prevent color surging.
Temperature Profile:
Feed Zone: 160°C - 170°C
Compression Zone: 180°C - 200°C
Metering Zone/Die: 200°C - 220°C
Note: Do not exceed 280°C to maintain the integrity of the carrier wax.
Screen Pack: The 2050 is filtered during manufacturing (water ring granulation), but we recommend using a 60-80 mesh screen pack on your extruder to ensure perfect homogeneity.
