High Strength Glass Fiber Reinforced Molding Compounds PF is a subcategory of Phenol-formaldehyde Plastic. The additative is added during the manufacturing process. Its elastic modulus ranges from 1900 to 3300 MPa. Its flexural modulus ranges from 1150 to 3300 MPa. Its tensile strength ranges from 7000 to 18000 MPa at break. Its flexural strength ranges from 12000 to 60000 MPa. Its compressive strength ranges from 16000 to 70000 MPa. Its Izod Impact strength ranges from 0.5 to 18 J/cm. Its hardness ranges from 54 to 101 Rockwell E. Its specific gravity ranges from 1.69 to 2. Its coefficient of thermal expansion ranges from 8 to 34 x 10^-6/°C. Its molding pressure ranges from 1 to 20 MPa.

Phenol-formaldehyde Plastic, also known as PF, is a thermoset polycondensate. The most common trade name is Bakelite. phenol-formaldehyde 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.
