Key performance characteristics of polypropylene color masterbatch!

The performance of polypropylene masterbatch needs to match the processing characteristics of polypropylene material (such as the extremely high requirement for dispersibility in spinning) and application scenarios (such as the need for weather resistance in outdoor products). The core features are as follows

Excellent dispersibility

Through the use of dispersants and special granulation processes (such as twin-screw extrusion granulation), pigments are uniformly dispersed in the carrier. After melting, they can quickly blend with the polypropylene resin, avoiding the appearance of "color spots" and "stripes" on polypropylene fibers/products. This is particularly suitable for polypropylene spinning (long and short filaments) scenarios - if the dispersion is poor, it will lead to filament breakage and uneven fiber dyeing.

Strong coloring stability

Good color reproducibility: The color masterbatch is in granular form, making measurement convenient (the addition amount can be precisely controlled through the feeder, with an error of ≤1%), and the color consistency of polypropylene products produced in different batches is high.

Temperature and weather resistance compatibility: The pigments have been screened and can withstand the high temperatures of polypropylene processing (160-180℃). Moreover, outdoor polypropylene color masterbatches (such as geotextiles and sunshade nets) can achieve a weather resistance of ≥3000 hours (xenon lamp aging test) by adding light-resistant pigments (such as rutile titanium dioxide).

Convenient and environmentally friendly processing

Compared with the direct use of powdered pigments, masterbatches do not produce dust flying, protecting the health of operators and avoiding pollution in the workshop.

Convenient color change: When changing colors, the equipment is easy to clean, reducing downtime (powdered pigments are prone to residue, and color change requires a long time for cleaning).

It does not affect the performance of the polypropylene substrate: The carrier is of the same origin as polypropylene and will not reduce the strength and toughness of polypropylene (for example, the breaking strength of polypropylene fibers decreases by ≤5%).

Wide applicability

The particle size (usually 2-4mm particles) and melt index of the color masterbatch can be adjusted according to the processing technology of the polypropylene product (spinning, injection molding, blown film, extrusion) to meet the requirements of different scenarios (for example, the color masterbatch used in spinning requires finer pigment dispersion, and the color masterbatch used in injection molding requires better fluidity).
