Woodflour Filled Molding Compounds PF is a subcategory of Phenol-formaldehyde Plastic. The additative is added during the manufacturing process. Its elastic modulus ranges from 800 to 1700 MPa. Its flexural modulus ranges from 1000 to 1200 MPa. Its tensile strength ranges from 5000 to 9000 MPa at break. Its flexural strength ranges from 7000 to 14000 MPa. Its compressive strength ranges from 25000 to 31000 MPa. Its Izod Impact strength ranges from 0.2 to 0.6 J/cm. Its elongation at break ranges from 0.4 to 0.8 %. Its hardness ranges from 100 to 115 Rockwell M. Its specific gravity ranges from 1.37 to 1.46. Its coefficient of thermal expansion ranges from 30 to 45 x 10^-6/°C. Its molding pressure ranges from 2 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.
