• Because of the low melt viscosity of Durastrength® 200 impact modifier, extrusion temperatures are lower, resulting in enhanced compound stability and output.
• Vinyl formulations employing Durastrength® 200 impact modifier exhibit reduced melt viscosity which helps to reduce extrusion pressures, prolonging screw and barrel life.
• The low melt viscosity of Durastrength® 200 impact modifier allows higher output without increasing extruder amps.
• The wide processing window of Durastrength® 200 impact modifier assures a consistently flawless surface finish.

Durastrength® 200 impact modifier is recommended for applications such as vinyl siding, window profiles and fencing where good outdoor weathering and low-temperature impact resistance are critical properties. Durastrength® 200 impact modifier is also ideally suited for impact modification of pipe, conduit and injection molded goods. Its low melt viscosity and rapid fusion characteristics are ideal for custom injection molding applications. Use of Durastrength® 200 impact modifier in injection molding formulations imparts excellent flow and high gloss to finished products.

Durastrength® 200 impact modifier may be used in formulations serving many end-use applications, including some flexible PVC applications. Customers should evaluate Durastrength® 200 impact modifier in their own laboratories to establish optimum conditions for use in their processes and applications. Arkema’s Technical Service Team is available to diskuss your application requirements, provide formulation guidance and laboratory testing as needed.

Durastrength® 200 impact modifier is packaged in 50lb bags and 1000lb bulk bags.
