We can provide you not only general phenolic resins but various type of special phenolic resins for electronic materials . You can apply them to electronic materials as epoxy raw material or curing agents, for general and special properties.

1.General phenolic resins 〔PS series〕.

These are high purity products refined to apply for electronic materials.

We have various types of special products but just introduce 2 well-known series.

BNC series

We succeed to increase to the highest content of Naphtol in Naphtol-cresol novolak phenolic resin.

It is expected not only hydrophobicity and high heat resistance, but better incombustibility.

Products and properties

	70	80	90
Softening point （℃）	68-72	77-83	85-95
Melt viscosity （Ps）	0.8-1.2	1.5-2.5	4-12
Hydroxyl equivalent	185-195	195-205	195-205

GPNX series

GPNX(Naphtol-phenol novolak phenolic resin) is improved of Xyloc, especially the feature of low water absorption and incombustibility. It is also expected better curing shrinkage.
