Cellulose Filled MF is a subcategory of Melamine formaldehyde. The additative is added during the manufacturing process. Its elastic modulus ranges from 1100 to 1400 MPa. Its tensile strength ranges from 5000 to 13000 MPa at break. Its flexural strength ranges from 9000 to 16000 MPa. Its compressive strength ranges from 33000 to 45000 MPa. Its Izod Impact strength ranges from 0.2 to 0.4 J/cm. Its elongation at break ranges from 0.6 to 1 %. Its hardness ranges from 115 to 125 Rockwell M. Its specific gravity ranges from 1.47 to 1.52. Its coefficient of thermal expansion ranges from 40 to 45 x 10^-6/°C. Its molding pressure ranges from 8 to 20 MPa.

Melamine formaldehyde, also known as MF, is a thermoset polycondensate. Common trade names include Bakelite, Isomin, Melaicar, Melbrite, Melmex, Melopas, Resart, and Ultrapas. It has high surface hardness and is scratch resistant. It is also highly resistant to creep, heat, moisture, and boiling water. Due to its high shrinkage rate, it is relatively easy to crack in formation. MF is commonly used in molding compounds and food containers such as bowls and dishes.
