EMS-Grivory Grivory® TR90 Transparent Nylon 12, As Conditioned (Unverified Data**)
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 12 (PA12)
Material Notes:	Grilamid TR 90 is a transparent polyamide with good heat resistance and excellent fatigue behavior. Grilamid TR 90 also exhibits low moisture absorption and dimensional stability. Grilamid TR 90 was developed for use in filter bowls, eye glass frames, tooth brushes and optical fiber containing cables. It may also be considered for a variety of consumer and industrial applications in which chemical resistance, transparency and toughness are desired. Because Grilamid TR 90 contains no plasticizer and resists cosmetic chemicals and perspiration, it can enhance the design and performance of personal products such as sport and safety spectacle frames. Grilamid TR 90 is NSF Standard 61 Listed. Information provided by EMS-Grivory
