An Overview of SAN Polymer Properties

Styrene Acrylonitrile Resin (SAN) polymer exhibits a comprehensive range of properties that contribute to its widespread utility across various industries. Here are the main SAN Polymer properties listed below!

The Main SAN Polymer Properties

Optical Clarity: Styrene acrylonitrile resin (SAN) is known for its excellent clarity. This makes it suitable for applications where transparent or translucent elements are required.

High Rigidity: It offers high rigidity, providing structural integrity and dimensional stability to the products manufactured using SAN polymer. This rigidity makes it suitable for applications that require stiffness and stability.

Flexible Design Features: With SAN Polymers, its ability to be easily coloured, moulded, and shaped allows for tailored design solutions, meeting specific application requirements.

Stays the Same Size: Have you ever seen something get all squished or warped when it gets hot or cold? SAN polymers don’t do that! They stay the same size no matter what temperature it is, which is handy for making things that need to keep their shape.

Improved Chemical Resistance: SAN polymer’s ability to withstand a broad spectrum of chemicals makes it more suitable for products that are subjected to different kinds of exposure. This property is especially important in applications where the polymer is in contact with solvents, acids, or other corrosive materials.
