Phenol [phenol formaldehyde resins (PF)]

Uniquely Kashima

Phenolic resin is a material with special features which make it very popular for plastic bearings. 

Overview of Phenol

Phenol plastic ( i.e., Bakelite, formaldehyde resin, carbolic acid resin )

Phenolic resin consists of phenol and formaldehyde thermosetting resin as raw materials, which are artificially synthesized from non-plant materials; first in the world of plastic.

Since it is produced from resins similar to phenols cresol, producers are frequently called phenol plastics including these “phenolic resins”.

Insulating, non-magnetic, highly resistant to oils and chemicals; strong heat resistance, but weak in alkalis.

Relatively inexpensive considering its superior performance
