SI6501 Transparent Silicone gel for IGBT modules,ECU, Sensor,Connector Potting
GEL 6501 is a transparent two-component self-healing silicone gel, which is formed into a solid gel material with strong cushioning and flexibility after curing. It is used to insulate circuit boards from moisture and other harmful contaminants, and to provide insulation against high voltages. Another use is to provide stress relief to protect circuits and interconnectors from high temperature and mechanical stress.
l 1:1 addition molding, good blistering
l Excellent flexibility, eliminate mechanical stress
l Very low oil permeability after curing, excellent resistance to toxicity
l High temperature electrical insulation is excellent, to provide protection against high pressure
l Excellent aging resistance and weather resistance
l Excellent waterproof, anticorrosive, moisture-proof, chemical medium resistance
l It can be used in semiconductor modules, connectors, sensors, etc
Typical Applications
Power semiconductor IGBT, load sensor, automotive ECU integrated module and other package protection IC chip, power telecommunication waterproof connector potting and sealing.
