Röhm ACRYLITE PLUS® ZK-M Impact Acrylic Polymer  (discontinued **)
Categories: Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, General Purpose, Molded; Acrylic, Heat Resistant, Molded; Acrylic, Impact Modified, Molded
Material Notes: ACRYLITE PLUS® ZK-M impact acrylic polymer is an amorphous, impact-modified thermoplastic molding and extrusion compound based on polymethyl methacrylate (PMMA).

Typical properties of ACRYLITE PLUS® impact acrylic polymers are high weather resistance, high light transmission, improved resistance to stress cracking, good melt flow rate, and easy to color.

The special properties of ACRYLITE PLUS ZK-M polymer are medium impact/break resistance and strength, low melt flow rate, high heat resistance, AMECA listed as ZKM (x), and FDA food contact use.

Application: Used for injection molded parts.
