Phenolic resin for refractory materials
Phenolic resin for refractory materials (Part one )
PF9180 Series
These resins can be divided into two series: thermoplastic and thermosetting, have the characteristics of high temperature resistance, high intensity etc, which can be used in the production of modified resin and bulk refractory materials such as coating and dry materials etc. Also can be used as the extender to improve the property of liquid resin. They can be applied to the plug, stopper, water gap, magnesia carbon brick, alumina-magnesia-carbon products etc, in order to improve the demanded wet strength.

Packing and storage
Powder: 20 kg or 25 kg/bag. Packed in woven bag with plastic liner inside, or in kraft paper bag with plastic liner inside. Resin should be stored in a cool, dry and well ventilated place far away from heat source to avoid moisture and caking. The storage life is 4-6 months below 20℃. Its color will become dark with long storage time, but will do not influence on the resin grade.
