SAN vs. Polycarbonate (PC)
Transparency : Both SAN and PC are transparent, but PC offers better shock resistance and thermal stability.
Cost : SAN is generally less expensive than PC plastic, making it a more cost-effective choice for applications that don't require extreme durability.
Applications : PC is used for applications requiring high durability and heat resistance, such as safety glasses and electronic enclosures. SAN is used for applications where clarity and chemical resistance are more important.
Table: Comparison of SAN with other polymers
Property SAN ABS PC PS
Chemical resistance High Moderate High Weak
Transparency Excellent Moderate Excellent Excellent
Heat resistance High High Very high Moderate
Cost Moderate Moderate High Weak
Common applications Food containers, cosmetic packaging, medical devices Automotive parts, electronic housings Safety glasses, electronic boxes Disposable items, insulation materials
Conclusion
Styrene-acrylonitrile (SAN) is a versatile and valuable plastic that combines the beneficial properties of styrene and acrylonitrile.

Its rigidity, transparency, and chemical resistance make it suitable for a wide range of applications, from packaging to household products to automotive to medical devices. By understanding the properties and modifications of SAN plastic, designers and manufacturers can effectively use this material to meet their specific needs.

Considering design, processing and environmental factors will ensure optimal use of SANs in various industries, contributing to both high quality products and sustainable practices.
