PC Masterbatch
PC Masterbatch (Polycarbonate Masterbatch) is a concentrated pellet formed by processing high-concentration pigments, functional fillers, and additives through specific techniques using polycarbonate (PC) as the carrier. It exhibits high compatibility with PC substrates, featuring high-temperature resistance and superior transparency. Suitable for engineering plastic products such as electronics, electrical components, and optical parts.

Advantages
Preserves PC Properties: High compatibility maintains PC’s inherent advantages, including high transparency, impact strength, and oil resistance, enhancing competitiveness.
Excellent High-Temperature Resistance: Utilizing PC resin as the carrier, it withstands processing temperatures of 260–300°C without decomposition or discoloration, making it suitable for high-temperature processes like injection molding and extrusion.
High Compatibility with PC Base Material: Matching the melt index of PC resin base material ensures uniform dispersion of pigments in the product, without compromising transparency or mechanical properties.
High Tinting Strength: Exceptional color concentration allows achieving the same effect with 10% masterbatch pigment content compared to 30% conventional pigment, effectively reducing costs and minimizing equipment cleaning frequency.
Easy Handling: PC masterbatch comes in granular form, facilitating precise metering and mixing. No additional process parameter adjustments are required, improving processing flow and saving time.
Excellent Environmental Compliance: Meets international standards such as ROHS, REACH, and FDA as required. Free from heavy metals and odors, suitable for electronic, medical, and food packaging products.
Strong Functional Expansion: Can incorporate functional additives like flame retardants, UV stabilizers, and antistatic agents for multifunctional applications, enhancing the comprehensive performance of finished products.

Production Process of PC Masterbatch
The production process of PC color masterbatch primarily includes the following steps:
1. Raw Material Screening: Typically involves selecting high-temperature resistant inorganic pigments or high-performance organic pigments, premium resins with excellent flow and mechanical properties, and additives meeting specific requirements, such as flame retardants.
2. Formulation Design: Calculate pigment and additive ratios based on target color or functional requirements. Develop precise formulations and pre-mix raw materials in machinery to ensure uniform distribution.
3. Melt Compounding: Pre-mixed materials undergo high-temperature heating and blending via twin-screw extruders. Impurities are removed through screens to enhance PC master batch purity.
4. Cooling and Pelletizing: The extruded PC melt (ribbon form) is typically cooled via water cooling (water bath cooling) or air cooling before being cut into pellets of the desired size.
5. Quality Inspection: Parameters such as appearance, particle size, color difference, melt index (MI), and thermal stability are tested. Non-conforming pellets are screened out to ensure batch consistency and application reliability.
6. Packaging and Storage: Masterbatch meeting quality standards is sealed in packaging, typically woven bags or composite bags, to prevent moisture ingress and maintain performance and appearance.
Common Types of PC Masterbatches
High-Gloss PC Color Master batch: Features high color stability with minimal haze or gloss loss, delivering high brightness, excellent color saturation, and superior surface finish. Commonly used in electronic enclosures, automotive interior components.
UV-Resistant PC Masterbatch (Weather-Resistant): Incorporates UV stabilizers to enhance yellowing resistance and outdoor weatherability. Suitable for outdoor transparent sheets, lighting shades, and security equipment housings.
Transparent PC Color Masterbatch: Utilizes high-transmittance pigment systems to maintain PC’s inherent transparency while achieving subtle tinting. Primarily used in light diffusion components, transparent electronic parts, and optical components.
Flame-Retardant PC Masterbatch: Incorporates halogen-free flame retardants to achieve UL94 V0 or V2 ratings. Widely used in home appliances and electronics to enhance safety standards.
Functional PC Master batch: Offers multiple functional properties including antistatic, antibacterial, scratch-resistant, and light-diffusing effects. Suitable for high-tech applications such as optical components and camera assemblies.
