Q1: What types of polymer systems is Colanyl Yellow FGL 132 VP3539 compatible with?
A: This color paste is specifically formulated for use in polyolefins (e.g., PP and PE), as well as engineering thermoplastics such as ABS, PS, and certain polyamides. It demonstrates good thermal stability during standard melt processing conditions and offers consistent dispersion without agglomeration.
Q2: How should this color paste be incorporated into the base polymer?
A: Colanyl Yellow FGL 132 VP3539 is designed for direct addition via gravimetric or volumetric dosing systems into extruders or injection molding machines. Pre-blending with carrier resin is not required, though masterbatch dilution may be used for fine-tuning shade intensity in high-precision applications.
Q3: Is this product suitable for food-contact applications?
A: Colanyl Yellow FGL 132 VP3539 is developed to meet general regulatory expectations for indirect food contact in plastics, subject to final formulation compliance and end-use processing conditions. Customers must verify suitability against applicable regional regulations and perform full migration testing as part of their own compliance process.
Q4: What is the recommended dosage range for achieving standard yellow shades?
A: Dosage depends on the target shade strength, polymer type, and processing method, but typical usage generally ranges from 0.1% to 2% by weight relative to the base polymer. Lower concentrations are often sufficient for bright, saturated yellows due to the high tinctorial strength of this pigment system.
