Unfilled Casting Resins PF is a subcategory of Phenol-formaldehyde Plastic. The additative is added during the manufacturing process. Its elastic modulus ranges from 400 to 700 MPa. Its tensile strength ranges from 5000 to 9000 MPa at break. Its flexural strength ranges from 11000 to 17000 MPa. Its compressive strength ranges from 12000 to 15000 MPa. Its Izod Impact strength ranges from 0.24 to 0.4 J/cm. Its elongation at break ranges from 1.5 to 2 %. Its hardness ranges from 93 to 120 Rockwell M. Its specific gravity ranges from 1.24 to 1.32.

Phenol-formaldehyde Plastic, also known as PF, is a thermoset polycondensate. The most common trade name is Bakelite. A naturally brittle material in pure form, it is able to be strengthened with fillers such as wood pulp and cellulose. PF is the first volume-produced synthesized polymer resin. It was widely used in early consumer electronic products such as telephones and radios.
