Covestro Baydur® 426 IMR RIM system
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Solid RIM
Material Notes:	Characterization: Baydur 426 IMR is a polyurethane high density structural RIM (HD SRIM) system. Properties / Applications: Baydur 426 IMR is a polyurethane high density structural RIM (HD SRIM) system used for automotive and light truck applications. This system is well suited for load bearing truck beds, tailgates, bumper beams, load floors, etc. It has excellent heat stability performance. Baydur 426 IMR composites can be used to replace steel or structural plastics for significant weight reduction ad lower tooling costs. Due to its inherent nature, this system is corrosion and abrasion resistant. The Baydur 426 IMR system can be processed with either a closed mold or open mold. This system is combined with a variety of glass reinforcements to make a structural composite. Glass mats, directed chop preforms or glass rovings can be used for reinforcement. This system has the appropriate reaction rate so that it can be used with a chopped glass fiber RIM machine. The Baydur 426 IMR system has an exceptionally long gel time, yet fast cure time, that makes it well suited for large automotive parts. Information provided by Covestro
