Glass Fiber Reinforced MF is a subcategory of Melamine formaldehyde. The additative is added during the manufacturing process. Its elastic modulus ranges from 1600 to 2400 MPa. Its tensile strength ranges from 5000 to 10500 MPa at break. Its flexural strength ranges from 14000 to 23000 MPa. Its compressive strength ranges from 20000 to 35000 MPa. Its Izod Impact strength ranges from 0.6 to 18 J/cm. Its specific gravity ranges from 1.5 to 2. Its coefficient of thermal expansion ranges from 15 to 28 x 10^-6/°C. Its molding pressure ranges from 2 to 8 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.
