Features & Benefits
Exceptional Impact Resistance
XENOY™ Resin 1731 offers outstanding toughness with a notched Izod impact strength of 667 J/m (23°C, ASTM D256). This ensures durability in extreme conditions, making it perfect for automotive exteriors and industrial machinery parts.
Superior Thermal Stability
With a high heat deflection temperature (HDT) of 115°C (0.45 MPa, ASTM D648), this resin maintains its shape and performance under thermal stress. This property is crucial for applications exposed to elevated temperatures, such as under-the-hood automotive components.
UV-Stabilized for Outdoor Use
Engineered with UV stabilization, XENOY™ Resin 1731 resists degradation from prolonged sunlight exposure. This feature is invaluable for outdoor applications such as automotive trims and construction materials, ensuring long-term durability and aesthetic retention.
