Q1: What is the primary application area for Colanyl Red FGRD 500?
A: Colanyl Red FGRD 500 is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers intended for food contact applications — where high thermal stability and excellent dispersion are required during extrusion or injection molding.
Q2: Is this color paste compatible with PP and PE processing conditions?
A: Yes, Colanyl Red FGRD 500 is formulated to withstand typical polypropylene and polyethylene processing temperatures (up to approximately 260 °C), offering good melt stability and minimal plate-out during high-output extrusion or blow molding operations.
Q3: How should the paste be incorporated into the polymer matrix?
A: It is recommended to introduce Colanyl Red FGRD 500 directly into the base polymer via gravimetric or volumetric dosing systems prior to extrusion. Pre-mixing with a portion of carrier resin may improve homogeneity, especially in high-viscosity or low-shear compounding setups.
Q4: Does this product meet regulatory requirements for food-contact applications?
A: Colanyl Red FGRD 500 is designed to comply with major global food-contact regulations for plastics, including FDA 21 CFR and EU Framework Regulation (EC) No 1935/2004, subject to final formulation and processing conditions. Confirmation of compliance for a specific end-use requires evaluation by the compounder or converter.
Q5: What is the typical dosage range for achieving target shade intensity?
A: Dosage depends on the base polymer, desired shade depth, and processing method, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the polymer — with optimal dispersion achieved using standard masterbatch incorporation practices.
