Phenolic resin for electronic materials

  • General product
  • Special product

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.

Comparison with general novolak.

Item Result
T.g. 30%up
Water absorption 40%down
Curing shrinkage 30%down
incombustibility Up to V-0

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.

Comparison with Xyloc

Item Result
Tg 20%up
Water absorption 20%down
Curing shrinkage 30%down
incombustibility Higher V-0
