TYNEL U4491 Tyne Plastics LLC. PEI 材料介紹:
玻璃纖維30%增強,耐熱性高POLYETHERIMIDE(PEI)
Advantages1. Continuous use temperature of 365degrees F (180 degrees C)
2. High strength
3. Inherently flame retardant
PERFORMANCE PROPERTIES
LONG-TERM HEAT RESISTANCE
Excellent stability of physicaland mechanical properties at elevated temperatures thanks to high glasstransition temperature of 217 °C. Available with relative thermal indices (RTI)up to 180 °C PERFORMANCEPROPERTIESLONG-TERMHEAT RESISTANCEExcellent stabilityof physical and mechanical properties at elevated temperatures thanks to highglass transition temperature of 217 °C. Available with relative thermal indices(RTI) up to 180 °C
STRENGTHAND STIFFNESS
Outstanding strengthand amorphous thermoplastic among the available alternatives, with predictablestiffness and strength up to 200 °C. Unfilled, transparent grades are equal instrength to other thermoplastics with opacifying fillers.
DIMENSIONAL STABILITY
Among the most dimensionallystable thermoplastics available, offering predictability over a widetemperature range. Filled grades offer exceptionally high-tolerance dimensionalcapabilities.
ENVIRONMENTAL STRESS & CRACKING RESISTANCE
Unlike most other amorphousthermoplastics, Ultem resins retain strength and resist stress cracking whenexposed to automotive and aircraft fluids, aliphatic hydrocarbons, alcohols,acids, and weak aqueous solutions
FLAMMABILITY, SMOKE GENERATION AND TOXICITY
Inherent flame resistancewithout additives in most grades - exceptionally difficult to ignite, with alimiting oxygen index (LOI) of 47%, meeting UL94 V0 specifications in sectionsas thin as 0.41 mm. Generates extremely low smoke per the NBS smoke evolutiontest, with products of combustion no more toxic than those of wood.
PROCESSABILITY
Can be extruded, thermoformed,extrusion blow molded and injection molded, and flowability permits long flowlengths down to 0.2mm thick using conventional injection molding equipment.
