ULTEM 7801 This RFQ was sourced on www.MFG.com in USA for Thermoplastics We are in need of a source for ULTEM 7801. The qty's listed are in U.S. LBS. Clean Pellet form to be used in the injection molding process of a critical component we use in our product. .125" pellets, Virgin, no re-grind. General Requirements the product should meet or exceed: CHEMICAL RESISTANCE Polyetherimide resists a wide range of chemicals including most hydrocarbons, alcohol’s, and fully halogenated solvents. It resists mineral acids and tolerates short-term exposure to mild bases. Partially halogenated solvents are acceptable to polyetherimide. HYDOLYTIC STABILITY Hydrolytic stability is good with greater than 85% tensile strength retention after 10,000-hr. boiling water immersion and 100% tensile strength retention after 2000 steam autoclaving cycles at 270°F. RADIATION RESISTANCE Polyetherimide has good resistance to UV and gamma radiation, the latter shown by a 94% retention of tensile strength after treatment of 400 megarads of cobalt irradiation. HEAT RESISTANCE Polyetherimide resins are rated for 338°F and 356°F continuous-use temperatures by Underwriters Laboratories, and are UL 94-VO listed down to 10 mils thickness depending on grade. Oxygen index is 47%. Polyetherimide complies with FAA flammability and heat release requirements for aircraft interior applications. Glass transition temperatures of 419°F and greater allow intermittent use at 392°F. and short-term excursions to higher temperatures. At 356°F., the tensile strength and flexural modulus are more than 6,000 and 300,000 psi, respectively. Higher strength and stiffness at elevated temperatures to the material’s glass transition (Tg) are obtained with glass or carbon fiber reinforcement. Long-term resistance to creep at high temperatures and stress levels allows polyetherimide to replace metal and other materials in many structural applications. ELECTRICAL Electrical properties show very good stability under variable temperature, humidity, and frequency conditions. OTHER PROPERTIES Low dissipation factor at GHz frequencies makes polyetherimide highly transparent to microwaves. The material also has low levels of ionic contaminants with conductivity of the water extract staying above 20 megaohms after 120 hr. extraction at 250°F., 100% RH, and 30 p.s.i.g., making it suitable for use as an insulation material for sensitive electrical components.
