The front and rear bumpers of Renault's new offering, Renault Laguna Coupe, features ExxonMobil Chemical's Exxtral™ performance polyolefins. Exxtral BMU131 performance polyolefin is being used for the front bumper, front grille and headlight trim, and Exxtral BMU133 polyolefin for the rear bumper. The Laguna Coupe application is an excellent example of collaboration between the automotive original equipment manufacturer (Renault), the Tier One supplier (Plastic Omnium), and the specialty compound supplier (ExxonMobil Chemical) to meet expectations across the supply chain.
Exxtral BMU131 polyolefin is a UV-stable grade exhibiting excellent aesthetics because of its broad processing window that helps to eliminate large-part injection molding challenges such as "tiger stripes." Requiring no mixing or blending at the molding presses, these ready-to-inject, fast-cycling grades can improve productivity and deliver cost-savings. As per the company, both grades are characterized by a unique impact strength that provides the essential balance between stiffness and toughness required for bumper applications. They offer a low coefficient of linear thermal expansion (CLTE) for excellent dimensional stability.
