1.2. What is ASA?

ASA plastic, also known as Acrylonitrile Styrene Acrylate, is a thermoplastic polymer developed as an alternative to ABS plastic. ASA exhibits greater flexibility and higher hardness compared to ABS, and it has better weather resistance. ASA plastic excels in its ability to resist aging and yellowing.

ASA plastic is a copolymer blend of acrylic rubber, acrylonitrile, and styrene. Specifically, ASA is formed from three monomers: acrylonitrile (AN), styrene (St), and acrylic (Ac).

2. The differences between ABS vs ASA plastics

ABS vs ASA plastics are both engineering plastics with numerous outstanding characteristics, widely applied in various fields. However, these two types of plastics also exhibit fundamental differences, including:

• Flexibility: ASA plastic possesses greater flexibility compared to ABS, meaning that ASA is better at resisting impacts and is less prone to deformation when subjected to external forces.
• Hardness: ASA plastic has higher hardness than ABS, which means it can withstand compressive forces better.
• UV resistance: ASA plastic offers superior UV resistance compared to ABS, which implies that ASA is less prone to discoloration or damage from UV radiation.
• Water resistance: ASA plastic has better water resistance than ABS, allowing it to be used in damp environments without water penetration.
• Glossiness: ASA plastic has a higher glossiness level compared to ABS, making it suitable for applications that demand a higher aesthetic appeal.
• Melting temperature: The melting temperature of ASA plastic is higher than that of ABS, allowing ASA to be processed at higher temperatures.

Both ABS vs ASA plastics are engineering plastics with numerous outstanding properties, and the choice between them depends on the specific requirements of each application.

3. Differences between ABS vs ASA filaments used in 3D printing

ABS vs ASA filament are two common materials used in 3D printing. Both are thermoplastic polymers, meaning they can be heated and molded into various shapes. However, there are several significant differences between them, including:

• 3D printing performance: ASA filament generally offers improved 3D printing performance compared to ABS filament. This is because ASA filament has lower shrinkage, resulting in higher precision in 3D printed models. Additionally, ASA filament is less prone to warping, leading to smoother and more aesthetically pleasing 3D printed surfaces.
• UV resistance: ASA filament excels over ABS filament in terms of UV resistance. This means that 3D printed products from ASA filament will not yellow or fade over time when exposed to sunlight.
• Chemical resistance: ASA filament also exhibits better chemical resistance compared to ABS filament. This makes ASA filament a better choice for applications requiring contact with corrosive chemicals.

Both ABS vs ASA filaments are suitable for 3D printing. However, ASA filament offers superior advantages in terms of UV resistance, chemical resistance, and improved 3D printing performance. Therefore, ASA filament is a better choice for applications that demand these properties.
