Chrome Iron Brown Hematite (PBr29)
Pigment Brown 29 (C.I. 77500) is a complex inorganic pigment of black mixed oxide of Iron (III) and Chrome (III) with chemical formula (Cr, Fe)2O3 and a hematite structure. It is a brownish to bluish black pigment.
We are a leading global manufacturer of Chrome Iron Brown Hematite (PBr29) black pigments that are opaque to visible light with high NIR reflectance ("cool" pigment).
Ferro PBr29 offers ease of dispersion and excellent dimensional stability, resulting in no warping or shrinkage.
Our pigment 24-3950 FCP (PBr29) is an ideal replacement to carbon black colorants used in plastics, specifically for use in recycling processes that utlize NIR sorting devices. It has been formulated to reflect light from the emitter, allowing the sensor to properly identify and sort various plastics.
Formulated to Meet Rigorous Food Contact Regulations
24-3950 FCP is part of our complete FCP product range that is AP89(1) certified for each lot (even at lower limits than the AP89(1) standard), and complies with the requirements established by EU 10/2011 regarding plastic packaging in contact with food and has acquired FDA approval (FDA 21 CFR 178.3297) to be used up to 5% in the final plastic material.
Ferro FCP black pigments are not only designed specifically to meet the requirements of individual polymer sorting via NIR reflection technologies, they also provide the color, processing, and surface finish properties needed across the diverse polymers required for food contact applications.

VALUE ADDED SERVICES
Advanced Color Matching
Ferro technicians combine their talents with today's most advanced computer color analysis equipment to offer our customers precise color-matching services. Our spectrophotometry process minimizes metamerism, speeds up color matching, ensures consistent quality and helps identify the pigment combination that produces any given color for the lowest possible cost and right performance characteristics, including outdoor durability and NIR reflectance.
Ferro can match your color chip/drawdown or we can refer to complete files of OSHA, Munsel, RAL, Federal Standard 595 Series or Pantone® matching systems to achieve your reference number. All of our colors are matched to Ferro standards or your reference sample, ensuring precise color reproduction from order to order.
Providing Formulation Guides/Assistance with Startup Formula Creation
We assist customers in their product development efforts to ensure regulatory compliance (e.g., usage in food, cosmetics) and desired performance including anticorrosion, outdoor durability and NIR reflectance.
Our laboratory facility teams support customers’ production and development activities, including accelerated corrosion testing, weatherability testing, heat build-up and total solar reflectance testing and migration testing.
Custom Formulations
We work closely with our customers to co-innovate and develop customized high-performing and economical coloring solutions based on application requirements and operational processing needs, including custom formulations for paints, coatings, cement, concrete, inks, ceramics, glass, leather, metal and plastics.
