Long Glass Reinforced Molding Compound PU is a subcategory of Polyurethane. The additative is added during the manufacturing process. Its elastic modulus ranges from 1700 to 2500 MPa. Its flexural modulus ranges from 1500 to 2200 MPa. Its tensile strength ranges from 27000 to 33000 MPa at break. Its flexural strength ranges from 45000 to 57000 MPa. Its Izod Impact strength ranges from 8 to 16 J/cm. Its coefficient of thermal expansion ranges from 0.6 to 0.8 x 10-6/°C.
Polyurethane, also known as PU, is a thermoplastic or thermoset, (typically reinforced), polyadduct. Common trade names are Estane and Pellanthane. thermoplastic It has high impact resistance, dielectric strength, chemical resistance, and abrasion resistance. It can be made into films, solid moldings, or flexible foams. However, it becomes brittle with prolonged outdoor exposure. It is often used in automotive structural members, computer housings, furniture, and packaging foams.
Other common Polyurethane (PU) include Casting Resin, Liquid PU, Casting Resin, Unsaturated PU, Unreinforced Molding PU, 30% Long Glass Fiber Reinforced PU, and 30% PAN Carbon Fiber EMI Shielding (conductive) PU.
