MAGNUM™ 555

About
MAGNUM™ 555 ABS resin is low gloss, low flow ABS resin that has a sheet Izod impact strength of 6.6 ft-lb/in. MAGNUM ABS resins are thermoplastic materials that provide an excellent balance of processability, impact resistance, and heat resistance as imparted by the various polymer compositions. MAGNUM ABS resins are available in a wide range of melt flow rates, impact strengths, and heat resistances for both high and low gloss applications manufactured by injection molding, sheet or profile extrusion, and thermoforming. The sheet and thermoforming grades of MAGNUM ABS resins provide excellent high and low gloss aesthetics, good thermal color stability, heat and impact resistance, and stiffness. MAGNUM ABS resins can fill a variety of needs by offering ranges in melt flow rates from 1.0 to 4.0, sheet Izod impacts from 2.5 to 10.5 ft-lb/in and sheet flexural modulus from 285,000 to 300,000 psi. Applications Burial vault liners Tool cases Recreational vehicles Luggage Signs Complies with: U.S. FDA 21 CFR 181.32 Consult the regulations for complete details.&&
