SEMINC Silicon Nitride Plates(Si3N4)
Using ultra-pure silicon nitride powder as raw material, combined with unique sintering technology, it can perfectly exert the characteristics of the material. Physical properties such as bending strength, thermal conductivity, CTE and breakdown voltage can reach theoretical values. (Product Specifications for details)


High Strength: Enabling thinner & lighter components. Improving heat dissipation efficiency.
High Thermal Conductivity: Extended service life and improved energy efficiency.
Low CTE: Matched with silicon (Si) and silicon carbide (SiC), it’s the most reliable choice.
High Breakdown Voltage: The performance of insulation is good, and no risk of leakage in high-power use.

UMP series products, which are granular type, have good fluidity. It has good operability, can be used for direct molding and injection molding machines. Molded products have a smooth and bright appearance, good dimensional stability, excellent mechanical strength and electrical properties. UMP series products passed UL flame-resistant certification for all colors, which can meet customers' needs for different colors. The following table shows the naming rules of UMP series products:
