ASA+ characteristics similar to ABS, but it offers better resistance to ultraviolet light and harsh weather conditions, with enhanced toughness, rigidity, and high impact resistance. Its excellent weatherability and mechanical properties enable it to better withstand the effects of environmental aging, making it commonly used for outdoor applications.
eSun ASA+ is an upgraded version of eSun eASA, offering improved UV resistance, higher heat tolerance, and enhanced mechanical strength—ideal for demanding outdoor and functional applications where durability matters most.
