Q1: What is the primary function of DIC PEONY L-618 Masterbatch in polymer processing?
A: DIC PEONY L-618 Masterbatch is a high-performance, thermally stable color masterbatch formulated for polyolefin applications, particularly polypropylene and polyethylene. Its main function is to deliver consistent, vibrant coloration while maintaining excellent dispersion, melt stability, and minimal impact on mechanical properties.
Q2: Is DIC PEONY L-618 suitable for food-contact or medical-grade applications?
A: DIC PEONY L-618 is designed with non-migrating, high-purity pigments and carrier resins compliant with general regulatory expectations for indirect food contact in polyolefins. However, final compliance depends on the complete formulation, processing conditions, and end-use requirements—users must conduct their own verification per applicable regional regulations.
Q3: How should DIC PEONY L-618 be incorporated into the base polymer?
A: It is typically added via gravimetric or volumetric dosing directly into the hopper of extruders or injection molding machines. Good mixing is achieved at standard processing temperatures for polyolefins; pre-drying is generally not required unless ambient humidity is exceptionally high or extended storage has occurred.
Q4: What is the typical dosage range for optimal performance?
A: Dosage depends on the desired color intensity, base resin, and processing method—but it is generally used at low concentrations, typically ranging from 0.1% to 2% by weight relative to the base polymer.
