Iron Oxide Black 730 – High Tinting Strength Pigment

Product Description

Iron Oxide Black 730 is a high tinting strength pigment developed specifically for film applications. The product delivers strong coloring performance, enabling manufacturers to achieve deep black coloration with lower pigment dosage compared to conventional black pigments.

This iron oxide black pigment is formulated for agricultural films and packaging plastic films, helping reduce material costs while maintaining uniform color performance. The optimized coloring efficiency makes it suitable for large-volume film production where cost control is essential.

High Coloring Efficiency

The primary advantage of Iron Oxide Black 730 is its exceptional tinting strength:

Strong Tinting Strength: The pigment provides intense coloration capability, allowing manufacturers to achieve desired black color intensity with reduced pigment addition to film formulations. (Tinting strength: 20-30% higher than standard iron oxide black, tested per ISO 787-24)

Cost-Effective Coloration: Due to high tinting strength, lower pigment quantities are required to achieve the same color depth as other black pigments, reducing material costs in film production. (Typical dosage: 0.5-2.0% for film applications, compared to 1.0-3.0% for standard pigments)

Dosage Optimization: Manufacturers can optimize pigment dosage while maintaining consistent black coloration, supporting efficient material usage in film manufacturing.

Reduced Pigment Consumption

Iron Oxide Black 730 helps minimize material requirements:

Lower Addition Levels: The high tinting strength enables manufacturers to use less pigment to achieve the target black color, directly reducing material costs per unit of film produced.

Material Cost Reduction: Reduced pigment consumption translates to lower overall material costs for large-volume film production operations.

Storage and Handling Efficiency: Lower pigment requirements reduce storage space and handling requirements for manufacturing facilities.

Uniform Appearance in Thin Films

The pigment provides consistent color quality in film applications:

Even Color Distribution: Iron Oxide Black 730 disperses uniformly in film matrices, ensuring consistent black coloration throughout the film without patchiness or streaking. (Particle size distribution: D50: 0.3-0.6 μm, D90: < 1.0 μm)

Thin Film Performance: The pigment maintains color uniformity even in thin film applications where color consistency can be challenging with conventional pigments.

Surface Appearance: Films containing Iron Oxide Black 730 exhibit smooth, uniform black appearance without color variations or defects.

Compatibility with Film Processing Requirements

The pigment is designed for integration into film production processes:

Film Processing Compatibility: Iron Oxide Black 730 is compatible with standard film processing conditions and equipment used in agricultural film and packaging film manufacturing.

Extrusion Process Integration: The pigment can be incorporated into extrusion processes used for film production without causing processing difficulties or affecting film quality.

Thermal Stability: The pigment maintains color integrity during film processing temperatures, ensuring consistent color development. (Thermal stability: ≤ 220°C for 30 minutes, ISO 787-22)

Agricultural Mulch Films

Iron Oxide Black 730 is suitable for agricultural film applications:

Black Mulch Films: The pigment provides deep black coloration for agricultural mulch films used in crop production, helping optimize film performance and cost.

Greenhouse Films: Black greenhouse films utilize the high tinting strength of Iron Oxide Black 730 for cost-effective light control and temperature regulation.

Agricultural Ground Covers: The pigment can be used in black agricultural ground cover films for weed suppression and soil moisture retention.

Packaging Plastic Films

The pigment serves various packaging film applications:

Flexible Packaging Films: Iron Oxide Black 730 provides black coloration for flexible packaging films used in consumer goods and industrial packaging. (Note: For food contact packaging applications, manufacturers must ensure compliance with applicable food contact regulations such as EU Regulation 10/2011 or FDA 21 CFR for the intended use case)

Shrink Films: Black shrink films benefit from the high tinting strength and cost efficiency of this pigment.

Stretch Films: The pigment can be used in black stretch films for industrial and commercial packaging applications.

Flexible Plastic Products

Beyond films, the pigment can be used in other flexible plastic applications:

Plastic Bags and Sacks: Iron Oxide Black 730 can be used for coloring plastic bags and sacks requiring black coloration.

Flexible Tubing: The pigment may be suitable for black flexible tubing applications where cost-effective coloring is needed.

Thin Plastic Sheets: The high tinting strength makes it suitable for thin plastic sheet applications requiring black coloration.

Production Cost Optimization

Iron Oxide Black 730 supports cost-efficient film manufacturing:

Lower Pigment Costs: Reduced pigment consumption directly decreases material costs per unit of film produced, improving profit margins in film manufacturing.

Large-Scale Efficiency: The cost benefits are particularly significant in large-volume film production where small per-unit savings accumulate to substantial total cost reduction.

Competitive Pricing: The high tinting strength allows manufacturers to offer competitively priced colored film products in the market.

Material Efficiency

The pigment enables efficient material utilization:

Optimized Formulations: Manufacturers can optimize film formulations to achieve desired color with minimal pigment content, reducing material waste.

Batch Consistency: The consistent tinting strength of Iron Oxide Black 730 supports stable production processes and predictable material usage.

Inventory Management: Lower pigment requirements simplify inventory management and reduce storage costs for film manufacturers.

Iron Oxide Black 730 maintains consistent quality for film applications:

Color Consistency: Each production batch maintains consistent tinting strength and color characteristics, ensuring uniform results across production runs. (Color difference ΔE ≤ 1.5 vs. reference standard)

Film Performance: The pigment does not adversely affect film properties such as flexibility, transparency requirements, or mechanical performance.

Processing Reliability: The pigment provides consistent performance during film processing without causing equipment issues or processing interruptions.
