Abstract: With the wide application of polyethylene wax (PE wax) in epoxy molding compound (EMC), the problem of poor mold release due to its oxidation under high temperature environment has become more and more prominent. Starting from the suppression of high temperature oxidation of PE wax, the effect of the addition of antioxidants on mold release and EMC product performance was studied. The results show that adding AO-60 or AO-412S these two antioxidants to EMC materials not only does not have a serious impact on the performance of the material itself, but also can effectively improve the problem of reduced mold release after a long time. With the increase in the amount of antioxidants, the improvement of mold release properties is first improved and then remains basically unchanged, and good results can be achieved when the addition amount is 5 phr.
