EMS-Grivory Grilamid? TR55 Transparent Nylon 12, Dry As Molded
Subcategory: Nylon; Nylon 12; Polymer; Thermoplastic
Material Notes:
Grilamid TR 55 is a uniquely versatile material. Based on Nylon 12, Grilamid TR 55 combines? excellent transparency with superior chemical resistance, strength, stiffness, toughness and outstanding process ability.
Transparency at any processable wall thickness is achievable with Grilamid TR 55. The excellent transparency is maintained even after prolonged exposure to boiling water. Grilamid TR 55 is NSF Standard 61 Listed and also complies with the requirements of CFR 21 Part 177, Section 1500 for nylon 12T resins in direct contact with food.
Typical applications for Grilamid TR 55 are fuel, air or water filter bodies, faucet and shower handles, electrical/electronic components and automotive parts.
