ASA and Luran® S: the perfect choice for long-lasting performance

Built for extremes, ASA (acrylonitrile styrene acrylate) is the material of choice for outdoor applications that need to withstand sun, heat, and time − while keeping products strong, reliable, and visually appealing.

Why ASA

Beyond its durability outdoors, ASA offers a balanced property profile that combines mechanical strength with design flexibility and is available in a wide range of colours. What sets it apart from many other plastics is its ability to maintain both durability and appearance under prolonged exposure to weather. While other polymers may lose colour or toughness when exposed to prolonged sun, heat, or moisture, ASA maintains its strength, gloss, and vibrant appearance over time. This makes it particularly well-suited for applications where long service life and surface quality are critical.

ASA‘s overall chemical robustness makes it the material of choice for automotive and construction components exposed to challenging weather conditions. Its acrylate rubber content further improves resistance to stress cracking, ensuring reliable performance even under chemical exposure.

Key benefits of ASA

· Design freedom: easily processed and available in a wide range of grades and finishes
· Reliable aesthetics: surfaces retain colour, gloss, and texture even after years of exposure
· Durability in use: resists mechanical stress, cleaning agents, and environmental factors
· Long-lasting appearance: butyl acrylate content prevents yellowing and aging, ensuring a stable property profile even under demanding conditions
· Proven performance outdoors: trusted across industries from automotive to construction where longevity matters
