Q1: What is the primary chemical composition of Cathay Masterbatch Red EP2300VA?
A: Cathay Masterbatch Red EP2300VA is based on a high-performance inorganic red pigment system, typically incorporating iron oxide or mixed metal oxide chemistries. It does not contain organic dyes or heavy-metal-based pigments such as cadmium or lead.
Q2: Is this masterbatch suitable for food-contact plastic applications?
A: Yes — EP2300VA is formulated to meet general regulatory expectations for food-contact plastics in major markets, including compliance with FDA 21 CFR §178.3297 for colorants in polyolefins and similar resins. Final compliance depends on the full formulation, processing conditions, and end-use requirements.
Q3: What is the typical dosage range when incorporating EP2300VA into polypropylene or HDPE?
A: Dosage is formulation-dependent but generally ranges from 0.1% to 2% by weight, depending on desired shade intensity, opacity requirements, and base resin characteristics. It is typically used at low concentrations due to its high tinting strength and excellent dispersion stability.
Q4: How does EP2300VA perform under elevated processing temperatures?
A: This masterbatch exhibits excellent thermal stability, maintaining consistent color and minimal degradation during standard extrusion and injection molding processes up to 280°C. Its inorganic pigment base ensures resistance to thermal fading and oxidation under typical industrial processing conditions.
