Electrical & Electronic Insulation: ATH Selection Guide for High-Reliability Systems
PF-1 and PF-AD1 Grades for Electronic Encapsulation, Potting Compounds, and Power Electronics Applications
Qingdao Pengfeng New Material Co., Ltd. supplies high-purity precipitated Aluminum Hydroxide (ATH) grades designed for electrical insulation, electronic encapsulation, and resin-based protection systems.
PF-1 and PF-AD1 are commonly used in electronic encapsulation compounds, electrical potting materials, industrial control systems, power electronics modules, and moisture-resistant insulation formulations where flame retardancy, chemical purity, electrical reliability, and processing consistency are important considerations.
When selecting ATH for electrical and electronic insulation applications, engineers typically evaluate factors such as particle size distribution, conductivity profile, chemical purity, bulk density, resin compatibility, and processing requirements according to the needs of the final formulation.
