Conductive Plastic Masterbatch China Suppliers and Factory for EMI Shielding
Our Conductive Plastic Masterbatch is a high-performance industrial additive engineered from high-strength ultra-fine stainless steel fibers integrated with specialized resins and adhesives. This advanced composite is designed to impart superior electrical conductivity to plastic components through a single-step injection molding process, eliminating the need for costly and time-consuming secondary treatments.
By bypassing traditional electroplating and conductive coating brushing, this solution significantly reduces production costs and material consumption while maintaining lightweight properties. Its versatile design allows for custom dyeing and seamless integration into a wide range of engineering plastics, making it an ideal choice for EMI shielding and anti-static applications in precision electronics.

Frequently Asked Questions
The primary advantage is the reduction in production steps. By integrating the conductive stainless steel fibers directly into the resin, you eliminate the need for secondary electroplating or brushing, which lowers labor costs and production time.
The HT-CH60-T12 model is designed for compatibility with TPE, TPU, PE, PVC, POM, PP, and PS resins.
Yes, it is specifically recommended for the structural parts of explosion-proof products to provide the necessary anti-static and conductive properties to prevent spark ignition.
The proportion (60% vs 75%) determines the level of conductivity and EMI shielding effectiveness. Higher proportions generally provide better electrical performance for more demanding industrial applications.
Absolutely. It is ideal for EMI shielding shells used in automotive electronics, ensuring that sensitive onboard computers and communication systems are protected from interference.
Standard packaging is 25kg per plastic bag with an outer carton box. However, we offer fully customized packaging solutions based on specific customer requests.
