- Low glass transition temperature: Our impact modifier has a glass transition temperature considerably below 0°C, which ensures that it stays flexible and impact resistant even in cold weather applications. This is critical for PA6 parts that must sustain impacts and prevent cracking or shattering in freezing temperatures.
- Anhydride Modification: The anhydride functional groups on our polyolefin backbone provide a high interfacial adhesion between the impact modifier and the PA6 matrix. This improves stress transfer during impact events, allowing the ductile elastomer phase to absorb and disperse impact energy.
- Superior impact performance: The combination of low Tg and anhydride functionality offers our impact modifier an extraordinary capacity to toughen PA6. Even with loadings as low as 10 wt%, we’ve seen over 100% increases in Charpy impact strength compared to unmodified PA6, with good impact resistance maintained down to -30 °C.
- Excellent processability: Our impact modifier is intended for simple inclusion into PA6 during compounding or injection molding. It has a low melt viscosity, making it easily distributed, and it has no substantial impact on the overall melt flow of the PA6 compound. This simplifies the process while also significantly improving toughness.
- Broad Compatibility: In addition to PA6, our impact modifier is compatible with a variety of other engineering thermoplastics, such as PC, PBT, and PET. This adaptability enables producers to use the same impact modifier in numerous resin systems, simplifying material handling and inventory management.
Advantage
mechanical properties are balanced: In addition to its remarkable impact performance, this impact modifier helps to maintain a balanced set of mechanical properties in PA6 compounds. It helps to retain the PA6 resin’s inherent stiffness and tensile strength while greatly increasing its impact resistance and toughness. The PA6 compound’s well-rounded mechanical qualities make it adaptable and suited for a wide range of applications that require a combination of strength, flexibility, and impact resistance.
Improved thermal and chemical resistance: This impact modifier contains anhydride-modified polyolefin elastomer, which improves the heat and chemical resilience of the PA6 compound. The anhydride activity increases the compatibility and adherence of the impact modifier to the PA6 matrix, resulting in a more cohesive and durable material system that can tolerate exposure to high temperatures and chemicals.
Diverse application possibilities: The low Tg anhydride-modified impact modifier for PA6 is used in a variety of sectors and end products. Its versatility and improved performance make it an excellent choice for automobile components such as bumper systems, interior trim, and under-the-hood elements. It is also suitable for recreational items, household appliances, and industrial applications that require high impact, durability, and temperature tolerance.
Customizable Formulations: This impact modifier can be further tailored to the unique requirements of various applications by adjusting its composition, molecular weight, and other factors. This adaptability enables formulators and manufacturers to customize the material’s qualities to obtain the ideal combination of mechanical, thermal, and processing attributes for their specific needs.
