Choosing the Right ASA Material for Demanding Outdoor Applications

The King of the Hill: Luran® S 777 K SE

Often considered the gold standard, this ASA material boasts an impeccable reputation. It is the benchmark for long-term weatherability, offering exceptional resistance to UV radiation and heat. For a guarantee of five years without fading or losing mechanical properties, even in consistently high temperatures, this ASA material is a proven and reliable choice. Its performance is backed by extensive real-world data, making it a safe bet for critical applications like automotive exterior parts.

The Powerful Contender: SABIC GELOY™ ASA XTWM206

SABIC's offering is a direct and formidable competitor. This high-performance ASA material is engineered to deliver outstanding color retention and durability against the elements. It matches the key requirements of high heat resistance and long-term UV stability, making it an excellent candidate for your five-year outdoor lifespan. For global projects, SABIC's extensive supply chain is a significant advantage.

The High-Value Performer: CHIMEI PW-978W

Don't overlook this exceptional ASA material from one of Asia's leading polymer producers. CHIMEI's PW-978W is formulated to provide excellent weatherability and thermal performance at a highly competitive price point. It confidently meets the stringent criteria of five-year outdoor use with minimal color fade. A key strength of this grade is its superb processability, which can lead to higher production efficiency and lower overall costs for high-volume manufacturing.

Making the Final Decision

All three of these advanced ASA material grades are more than capable of meeting the challenge of long-term outdoor exposure. Your choice may ultimately come down to:

• Brand Preference and Historical Data: Luran S is the established benchmark.

• Supply Chain and Support: SABIC offers robust global support.

• Cost-Efficiency and Processing: CHIMEI provides outstanding value.

The best practice is to obtain samples of each ASA material, conduct accelerated weathering tests (like QUV), and run trial molds. Seeing the data and the finished parts for yourself is the only way to make the perfect choice for your specific application.
