Heliogen Blue

Updated: 2026-07-15

Overview

Heliogen Blue, also known as Phthalocyanine Blue (PB15), is a synthetic organic pigment widely recognized for its intense blue color and superior performance in industrial applications. It belongs to the phthalocyanine family, which is known for its excellent lightfastness and chemical stability. The pigment is commonly used in plastics, coatings, inks, and textiles due to its vibrant hue and durability. First synthesized in the early 20th century, Heliogen Blue has become a staple in the colorant industry. Its molecular structure includes a copper-phthalocyanine complex, which contributes to its stability and resistance to fading. The pigment is available in various forms, including powder and dispersions, to suit different manufacturing processes.

Physical and Chemical Properties

Heliogen Blue is a deep blue powder with a density ranging from 1.50 to 1.70 g/cm³. It has a high melting point, exceeding 300°C, and is insoluble in water but soluble in concentrated sulfuric acid. The pigment exhibits excellent lightfastness, making it suitable for outdoor applications where exposure to sunlight is a concern. Its chemical stability ensures resistance to acids, alkalis, and solvents, which is critical for industrial uses. The pigment's particle size and surface treatment can be adjusted to enhance dispersion in various matrices, such as polymers and resins. These properties make Heliogen Blue a versatile choice for demanding applications.

Main Applications

Heliogen Blue is extensively used in the plastics industry to color products such as packaging, toys, and automotive parts. Its thermal stability allows it to withstand high processing temperatures without degradation. In coatings, the pigment provides long-lasting color for architectural and industrial paints, including those exposed to harsh environmental conditions. The printing industry relies on Heliogen Blue for inks used in packaging, publications, and textiles. Its vibrant shade and resistance to bleeding make it ideal for high-quality prints. Additionally, the pigment is used in artistic paints and dyes, where color consistency and durability are paramount.

Safety and Storage

While Heliogen Blue is generally considered safe for industrial use, precautions should be taken to minimize exposure. Inhalation of pigment dust can irritate the respiratory system, and skin contact may cause mild irritation. Personal protective equipment (PPE), such as gloves and masks, is recommended during handling. Storage conditions are critical to maintaining the pigment's quality. It should be kept in a cool, dry place, away from direct sunlight and moisture. Containers should be tightly sealed to prevent contamination and dust formation. Proper labeling and adherence to safety data sheets (SDS) are essential for safe storage and handling.

B2B Procurement Guide

When procuring Heliogen Blue, B2B buyers should prioritize quality and consistency. Key factors to consider include purity, particle size, and dispersion properties, which can affect the pigment's performance in specific applications. Requesting product samples and technical data sheets can help evaluate suitability. Suppliers should provide certifications such as ISO or REACH compliance to ensure regulatory adherence. Pricing varies based on quantity and purity, with bulk purchases typically offering cost savings. Lead times and logistics should also be considered to align with production schedules. Establishing long-term relationships with reputable suppliers can ensure reliable supply and consistent quality.
