    Application
    Acrylonitrile Styrene (AS or SAN) serves as a versatile copolymer widely utilized for its balance of physical properties in various applications. Available in the form of clear white pellets, AS is commonly extruded into thin tubing and can undergo processes such as biaxial stretching. This material is characterized by its notable tensile strength of approximately 15,000 psi (103 MPa) and its high transparency, making it an ideal choice for protective uses. Its high coefficient of static friction (0.95) also contributes to its effectiveness in packaging and protective applications, particularly in the household sector for food wrapping. Additionally, AS exhibits low permeability to gases like oxygen and nitrogen, enhancing its utility in maintaining freshness and extending shelf life. The polymer's compatibility with organic solvents allows for its application as a solution coating, improving both vapor resistance and printability on substrates like polyethylene and cellophane. These attributes highlight its contribution to increasing mechanical strength and functionality, particularly when processed through methods such as cold drawing, which can significantly enhance its tensile strength.
