Product details

Highly active microsilica for epoxy plastic sealer:This type of silica fume is commonly used in the electronics field to make epoxy plastisols.highly active micro silicon powder filled into the epoxy sealing material can significantly improve the hardness of epoxy resin, increase the thermal conductivity, reduce the exothermic peak temperature of the reaction of the epoxy resin curing material, reduce the linear expansion coefficient and the curing shrinkage, reduce the internal stress, improve the mechanical strength of the epoxy sealing material, reduce the epoxy sealing material of the phenomenon of cracking, thus effectively preventing the entry of external harmful gases, moisture and dust into the electronic components or integrated circuits to slow down the vibration, prevent external damage and stabilise the parameters of the components. vibration, prevent external damage and stabilise component parameters.The main composition of common epoxy encapsulants is 60-90% filler, 18% or less epoxy resin, 9% or less curing agent and 3% or so additives. The inorganic filler used is basically silicon powder, the content of which is up to 90.5%.
