Styrene-Acrylonitrile (SAN)
Description (definition)
SAN (styrene acrylonitrile) is a transparent, thermoplastic material characterized by high chemical resistance, rigidity and surface hardness. It is inexpensive and easy to process, making it suitable for a wide range of applications such as household goods, packaging and technical components. SAN also offers excellent dimensional stability and optical clarity.
Example
A typical example is the use of SAN in transparent containers for household appliances such as coffee machines or blenders. Its high chemical resistance makes it ideal for contact with food and cleaning agents.
What advantages does SAN offer compared to polystyrene (PS)?
SAN has a higher chemical resistance, better heat resistance and increased rigidity compared to pure polystyrene. SAN is also less susceptible to stress cracking and offers a better surface quality.
Where is SAN used in the industry?
SAN is used in the household appliance industry for containers, lids and transparent components. In the cosmetics industry, it is used for bottles and packaging that require high optical quality.
Is SAN recyclable?
Yes, SAN is recyclable and is often reused in closed loops. Recycled SAN is often used in less demanding products such as containers or technical housings.
