Dow introduced Dowsil EG-4175 Silicone Gel, a enormously reliable preventive solution for next-generation separated gate bipolar transistor (IGBT) modules that perform at higher voltages. This latest superior material oppose the higher temperatures related with these IGBTs and helps more reliability, reduce power losses and higher power efficiencies in electric vehicle (EV) batteries and inverters for photovoltaic (PV) panels and wind turbines.
Dow’s recent DOWSIL EG-4175 Silicone Gel withstands temperatures as much as 180°C and increasing Dow’s developing portfolio of solutions for power electronics. The material additionally absorbs vibrations and has self-recovery properties that restore small cracks without external intervention. It attributes self-priming adhesion for improved module safety and treatment plans at room temperatures for remarkable energy performance. Heat-expanded healing will also be used to reduce cycle times.
“Dow is improving our IGBT materials portfolio to speak the rising trend closer to reaching higher power densities,” stated Cathy Chu, international strategic advertising director, Consumer & Electronics, Dow. “With its better-temperature resistance as contrasted to incumbent substances, this latest silicone gel will allow our customers to design and produce better-density IGBT modules with more power system performance. This shows Dow’s dedication to advancing the EV and renewable energy sectors, both of which make contributions considerably to worldwide carbon reduction.”
The release of DOWSIL EG-4175 Silicone Gel helps main traits in EVs and renewable energy. In EVs, battery voltages are boosting from 400V to 800V to permit more efficient main inverter and faster battery charging. In PV panels and wind turbines, the energy densities of inverters are growing. This advancing of power efficiency and helps the coping with of more electric loads. With better junction temperature related with higher voltages and more electrical loads of the 7th generation IGBT technology, a silicone gel require to have strong dielectric features and more improved thermal resistance.
Dow’s portfolio of silicone-based dielectric gel products gives thermal resistance, electrical insulation, encapsulation, stress comfort, and mechanical and environmental protection. The corporations advanced DOWSIL EG-4175 Silicone Gel builds on those houses to give numerous different advantages, inclusive of high-temperature resistance, low stages of silicone oil bleed and adhesion without a primer. Gels are a unique class of encapsulant that could treatment to an extremely soft material at the same time as giving the dimensional stability of an elastomer.
