1. Excellent impact resistance that is equivalent to or better than alternative non-acrylic impact modifiers.
Typical Impact Resistance [Izod Impact Performance (Siding Substrate Formulation @ 4.5phr Modifier)]
2. Faster fusion than alternative non-acrylic impact modifiers without the need for additional processing aids.
Typical Torque Rheometer Fusion
Torque Rheometer Curves Settings: 175°C, 75 RPM and 100 cc sample size Impact modifiers evaluated at 4.5 phr
3. Substrate applications utilizing Durastrength® 4000 impact modifier maintain important mechanical properties for final PVC product performance.
Typical Mechanical Property Performance (Tensile Evaluation)
Evaluation followed ASTM D-638 Impact modifiers tested at 4.5 phr
4. Durastrength® 4000 impact modifier has traditional acrylic characteristics such as a low melt viscosity which when employed in a vinyl formulation results in good stability, smooth processing, and high output rates.
Applications & Uses
- Plastics & Elastomers End Uses
- Suggested Use Levels
Durastrength® 4000 impact modifier is recommended for applications requiring impact properties in addition to ease of processing such as siding, fence and deck substrate. As with all impact modifiers for PVC, proper formulation is required to develop the necessary shear and mixing during extrusion so that impact properties are optimized.
Prospective clients should evaluate Durastrength® 4000 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 discuss your application requirements, provide formulation guidance, and laboratory testing as needed.- Typical Starting Formulation Recommendations
