Introduction
High purity linear phenolic resin has the characteristics of narrow molecular weight distribution, low content of free phenol and foreign ion (ppm grade). It provides excellent heat resistance and stable mechanical properties for electronic devices, and can also be used as an intermediate of special epoxy resin.
