Windbond PF 101 L

General

Phenol formaldehyde resins (PF) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Phenol resins are mainly used in the production of circuit boards. They are better known however for the production of molded products including pool balls, laboratory countertops, and as coatings and adhesives. In the form of Bakelite, they are the earliest commercial synthetic resin..

1. Application of Phenol Formaldehyde Resin

Phenolic resins are found in myriad industrial products and laminates are made by impregnating one or more layers of a base material such as paper, fiberglass or cotton with phenolic resin and laminating the resin saturated base material under heat and pressure. The resin fully polymerizes (cures) during this process. The base material choice depends on the intended application of the finished product. Paper phenolics are used in manufacturing electrical components such as punch-through boards and household laminates. Glass phenolics are particularly well suited for use in the high speed bearing market. Snooker balls as well as balls from many table-based ball games are also made from phenol formaldehyde resin. Phenolic resins are also used for making exterior plywood commonly known as WBP (Weather & boil proof) Plywood because Phenolic resins have no melting point but only a decomposing point in the temperature zone of 220 degree Celsius & above.
