Metton® LMR M15XX

About
The Metton LMR reaction injection molding process can provide large parts in low pressure molds with the mechanical property performance similar to injection molded engineering thermoplastics. The combination of Metton LMR’s process and material capabilities result in a new design freedom for replacing traditional materials such as metal, wood and fiberglass. Fiber reinforced products tend to have poorer durability, but higher equivalent section modulus. In most semi-structural applications, Metton LMR can be designed to provide equivalent part stiffness for performance and generally at a significant weight reduction. This section contains polymer property data necessary to initially assess the compatibility of Metton LMR with a particular application. The Metton LMR product family includes a standard M15XX product line and a flame-retardant product which meets the requirements for classification as U.L. V-O. The Metton M15XX includes the products M1534, M1537, M1539 and M1540. The Metton V-0 product uses a special three stream RIM injection machine.&&
