Overview
High concentration yellow masterbatch is a pre-dispersed pigment concentrate used to color plastics uniformly. It consists of 20-50% pure pigment embedded in a carrier resin (e.g., PE, PP, or PS), ensuring ease of handling and consistent coloration during processing. Unlike powder pigments, masterbatches reduce dust pollution and improve workplace safety. They are widely adopted in extrusion, injection molding, and other thermoplastic processes due to their cost-effectiveness and scalability.
Physical and Chemical Properties
The masterbatch exhibits high thermal stability (up to 300°C for some grades), making it suitable for high-temperature processing. Its granular form ensures free-flowing properties, preventing clogging in feeding systems. Key chemical properties include lightfastness (resistance to fading under UV exposure) and compatibility with common polymers. The concentrated formulation allows low dosage rates (typically 1-5% by weight), reducing production costs.
Main Applications
Primary uses include packaging films (e.g., food bags, shrink wraps), household products (buckets, containers), and automotive parts (dashboards, trims). The bright yellow shade is also popular for safety equipment and toys. In textile applications, it colors synthetic fibers like polyester. Specialty grades meet FDA/EU food-contact standards for disposable cutlery and beverage bottles.
Safety and Storage
Store in sealed containers at <30°C to prevent moisture absorption. Although non-hazardous under normal conditions, overheating during processing may release volatile organic compounds (VOCs). Use local exhaust ventilation and wear gloves/masks when handling. Spills should be cleaned with dry methods; avoid water to prevent environmental contamination.
B2B Procurement Guide
Industrial buyers should specify pigment concentration, carrier resin type, and end-use requirements (e.g., UV resistance, FDA compliance). Request technical datasheets and samples for trial runs. Bulk purchases (500kg+) often secure 10-15% discounts. Partner with suppliers offering just-in-time delivery to minimize inventory costs. Verify ISO 9001 certification for quality assurance.
