1. **Introduction to EVA Color Masterbatch:** This series of masterbatches is formulated with specific carrier resins and high-concentration composite colorants, processed through high-speed mixing and twin-screw extrusion compounding. It is suitable for coloring resins such as PE, PP, EVA, PS, and ABS, and is widely used in the processing of plastic products including extrusion, injection molding, cast film, blow molding, hollow blow molding, and coating. 2. **Main Technical Specifications of EVA Color Masterbatch:** - Appearance: Uniformly colored cylindrical, round, or flat-round granules. - Dispersibility: No color spots or streaks. - Heat Resistance: 200-300°C. - Migration Resistance: ≥4 grades. - Lightfastness: 4-8 grades. 3. **Usage Ratio and Method for EVA Color Masterbatch:** Mix the masterbatch with raw resin at a ratio of 1:10-50 (depending on specific product requirements) and use after thorough mixing (drying may be necessary). 4. **Advantages of Using EVA Color Masterbatch:** - Ensures optimal dispersion of pigments and achieves color stability across different batches of colored products. - Maintains the chemical stability of pigments and other additives, reducing thermal degradation of plastic materials. - Easy operation, environmentally friendly, significantly reduces labor intensity, and facilitates the automation of plastic product processing.
