Cost: It can be more expensive than other general-purpose plastics like polystyrene, which can increase the overall manufacturing cost for some applications and potentially make it less competitive in cost-sensitive markets.
Environmental concerns: It is less recyclable than other plastics, which can contribute to environmental waste if not properly managed, and poses a challenge to sustainability efforts.
Processing Challenges: Although SAN/AS is forex dataseteasy to process, maintaining precise control of processing conditions is essential to avoid defects such as
SAN/AS Changes
To improve the properties of SAN plastic, manufacturers can modify it or blend it with other materials. These modifications aim to improve mechanical properties, chemical resistance and thermal stability, thereby expanding the range of applications of SAN.
Mixing with rubber
Composition : Manufacturers may mix it with rubber to improve its impact resistance.
Improved Properties : The addition of rubber increases the strength and flexibility of SAN, making it less likely to crack.
Applications : This modified SAN is used in applications requiring high impact resistance, such as electronic enclosures and consumer goods.
Fiberglass reinforcement
Composition : It can be reinforced with glass fibers to improve its mechanical properties.
Improved properties : This modification increases the stiffness, impact resistance and dimensional stability of the material. The transparency of SAN/AS is maintained, which allows for high-quality surfaces.
Applications : Glass fiber reinforced SAN is used in demanding environments, such as automotive parts and high performance electrical components.

Co-polymerization with acrylics
Composition : Manufacturers can copolymerize this material with acrylics such as PMMA (Polymethyl Methacrylate).
Improved Properties : This copolymerization improves the UV resistance, chemical resistance and optical clarity of SAN.
Applications : SAN-Acrylic copolymers are used in exterior applications, optical lenses and products requiring high transparency and durability.
