Q1: What is the primary application field for FF-12 EVA Organic Pigment?
A: FF-12 is specifically engineered for coloration of ethylene-vinyl acetate (EVA) copolymers, especially in solar module encapsulants, footwear soles, adhesives, and flexible packaging films where thermal stability and dispersion performance in EVA matrices are critical.
Q2: Is FF-12 compatible with standard EVA processing conditions?
A: Yes — FF-12 exhibits excellent thermal stability during typical EVA melt processing (e.g., extrusion, calendering, and lamination), maintaining color integrity without significant degradation or gas evolution up to 180–200 °C for standard residence times.
Q3: How should FF-12 be dispersed in EVA resin?
A: For optimal results, pre-mix FF-12 with a portion of EVA resin using high-shear blending, followed by melt compounding. Masterbatch dilution is recommended for precise dosing and uniform distribution; direct addition to molten EVA may lead to agglomeration if not adequately pre-dispersed.
Q4: Does FF-12 meet regulatory requirements for food-contact or photovoltaic applications?
A: FF-12 is formulated without heavy metals or known restricted aromatic amines, supporting compliance with general industry expectations for non-food-contact EVA applications such as solar encapsulation. Regulatory suitability for specific end uses must be confirmed through final formulation testing and applicable regional assessments.
Q5: What is the typical dosage range for FF-12 in EVA formulations?
A: Dosage depends on the desired shade strength and opacity, but FF-12 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to the EVA matrix — due to its high tinctorial strength and efficient dispersion behavior.
