Q1: What types of polymer systems is Colanyl Blue B2G 500 compatible with?
A: Colanyl Blue B2G 500 is formulated for use in polyolefins—including PP and HDPE—as well as certain engineering thermoplastics such as ABS and PS. It demonstrates good thermal stability during standard extrusion and injection molding processes.
Q2: How should this color paste be incorporated into a polymer formulation?
A: The paste is typically added directly to the base polymer using standard masterbatch dilution techniques—such as twin-screw extrusion or high-speed mixing—ensuring uniform dispersion. Pre-drying is not required, but handling under low-humidity conditions is recommended to maintain consistency.
Q3: Is Colanyl Blue B2G 500 suitable for applications requiring regulatory compliance for food contact or toys?
A: This product is designed for industrial and general-purpose applications. For regulated end-uses—including food-contact plastics or children’s products—formulators must conduct full system-level compliance verification, as regulatory approval depends on final composition, processing conditions, and intended application.
Q4: What is the typical dosage range when using this paste in polyolefin applications?
A: Dosage depends on the desired shade intensity and base polymer characteristics, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the total formulation.
