摘要:
A rubber-modified phenolic resin composition contains a novolak-type phenolic resin in which at least one modifying agent selected from the group consisting of an ABS resin and an MBS resin is homogeneously dispersed. The composition has good impact resistance and thermal shock resistance. The composition is prepared by adding at least one modifying agent described above to a novolak-type phenolic resin which is heated and melted at its softening point or more, so that the modifying agent is homogeneous dispersed in the resin. The resin composition is suitably used as a curing agent for an epoxy resin encapsulant for sealing electronic devices.
摘要:
An epoxy resin composition for encapsulation of semiconductor device comprises the components (a), (b), (c) and at least one of the components (d) and (e) as shown below:(a) 100 parts by weight of an epoxy resin having at least 2 epoxy groups in one molecule;(b) 8 to 65 parts by weight of a novolak type phenolic resin with an ortho ratio less than 50%;(c) 1.2 to 40 parts by weight of a polyvinyl acetal compound;(d) 0.8 to 30 parts by weight of a silicone oil; and(e) 4 to 80 parts by weight of a rubber-modified phenolic resin.The described epoxy resins composition for encapsulation of semiconductor devices can retain its high glass transition temperature in the cured product and also has low modulus of elasticity, as well as excellent humidity resistance and thermal shock resistance.
