EMI Shielding Plastic
Next-generation lightweight shielding material that blocks electromagnetic interference
Overview
As vehicles incorporate more electronic devices and communication modules, EMI (Electromagnetic Interference) shielding has become essential for safe and stable data transmission. Traditional metal components are heavy and lack processing flexibility, limiting weight reduction and cost efficiency.
LG Chem’s EMI Shielding Plastic delivers approximately 30% weight reduction and cost savings compared to metal, while maintaining excellent EMI shielding performance. Its injection molding process enables complex structures, ensuring both design flexibility and productivity. This allows customers to achieve secure data protection and improved vehicle efficiency simultaneously.
