10 - 20% Glass Fiber Reinforced PP is a subcategory of Polypropylene. The additative is added by weight during the manufacturing process. Its flexural modulus ranges from 355 to 510 MPa. Its tensile strength ranges from 5000 to 8000 MPa at break. Its flexural strength ranges from 7000 to 11000 MPa. Its compressive strength ranges from 5500 to 5600 MPa. Its Izod Impact strength ranges from 0.95 to 2.7 J/cm. Its elongation at break ranges from 3 to 4 %. Its hardness ranges from 100 to 103 Rockwell R. Its specific gravity ranges from 0.98 to 1.04. Its melting temperature ranges from 160 to 168 °C.
Polypropylene, also known as PP, is a thermoplastic, (crystalline), polymer. Common trade names are Marlex HGL and Fortilene 1800 series (FDA materials). copolymer Its key attributes are high lubricity, high resistance to flexing (excellent material for living hinges), excellent dielectric strength and chemical resistance, good impact strength, and high solvent resistance. It is inexpensive and electroplatable, but it is difficult to paint, print on, or bond to. It will be attacked by fuming nitric acid and degraded by UV and ionizing radiation. PP can be used to make medical syringes, beakers, and parts for auto interiors.
