PUR system comes stateside

High glass-transition temperatures combined with low smoke and fire spread ratings that made a polyurethane (PUR) resin system well-suited for high-heat applications in the European aerospace, automotive, rail and electrical markets since the 1970s, will now look to propel the technology in the U.S., with a North American launch for the PUR in early September. The Blendur polyurethane resin systems were introduced to the North American market at the CompositesWorld Expo (Sept. 3-5, Schaumburg, IL).


Blendur can be formulated to meet specific composite applications requirements, with one- and two-component systems offering viscosities ranging from 30 to 2500 mPas, and pot life and gel times between 10 minutes and six hours. Blendur can also be made to react at room temperature. Properties include low thermal expansion; chemical and hydrolysis resistance; glass transition of 280°C; heat resistance to 240°C; high long-term thermal stability at over 200°C; and reportedly excellent mechanical and electrical properties up to 200°C.


Composite materials made from Blendur offer inherent fire performance properties and common thermoset manufacturing processes like resin transfer molding, vacuum-assisted resin infusion, filament-winding, pultrusion, prepreg manufacture, mold construction, casting, and injection molding can be used for part creation.
