Main characteristics of PEI:
1. PEI's Chinese name (polyetheryl) is an amber transparent solid with good flame retardancy and low smoke, with a combustion rating of UL94-V-0.
2. PEI has strong high-temperature stability High temperature resistance, with a thermal deformation temperature of up to 220 ℃, can be used for a long time at a working temperature of -160 to 180 ℃.
3. Good hydrolysis stability, high temperature resistance, and steam resistance
4. Polyether acyl has excellent resistance to UV and Y rays.

PEI is a thermoplastic engineering resin with excellent stability. PEI resin can withstand long-term high temperature tests. This high heat resistance, combined with excellent flammability and UL laboratory certification, makes PEI resin meet the demanding requirements of high-temperature applications. 3 . PEI resin has both high strength and high modulus characteristics, as well as ductility. Its yield tensile extension allows it to freely combine various snap fit designs that are easy to assemble. Even with only 10% glass fiber reinforcement added, PEI 2100 resin can maintain ductility in the temperature range below zero to 200 ℃. 4 . PEI 1000 resin has excellent practical impact resistance. Given that PEI resin exhibits notch sensitivity, it is recommended to follow standard design principles. The application force concentration points (such as sharp corners) in injection molded parts should be minimized to provide high impact strength. PEI AT * 100 resin is specifically designed for applications that require high impact performance. The Izod impact of this series can reach 15km/m. 5 . Fatigue resistance is an essential design consideration for cyclic loading or swinging components. 6 . When considering the mechanical properties of any thermoplastic, designers must recognize the impact of temperature, stress levels, and load duration on material properties. Even at temperatures and stress levels where many other thermoplastic materials cannot be used, PEI resin exhibits good creep resistance. PEI resin has excellent electrical properties and can maintain stability under a wide range of environmental conditions. Combined with its thermal and mechanical properties, PEI resin is an ideal choice for demanding electronic and electrical applications. 8. (Relative dielectric constant) Although applications may require high or low relative dielectric constant values, it is essential that these values remain stable throughout the entire temperature and/or frequency range of use.

Specific performance and model of PEI:

ULTRAM UF5011S PEI is an amber transparent solid with inherent flame retardancy and low smoke without the addition of any additives. It has an oxygen index of 47%, a combustion rating of UL94-V-0, and a density of 1.28-1.42g/cm3. PEI has strong high-temperature stability, and even non reinforced PEI still has good toughness and strength. Therefore, the superior thermal stability of PEI can be used to produce high-temperature heat-resistant devices. It has excellent mechanical properties, electrical insulation properties, radiation resistance, high and low temperature resistance, and wear resistance, and can transmit microwaves. PEI has good flame retardancy, chemical resistance, and electrical insulation properties. The glass transition temperature is very high, reaching 215 ℃. And PEI has a very low shrinkage rate and good isotropic mechanical properties. Adding glass fiber, carbon fiber or other fillers can achieve the purpose of reinforcement and modification; It can also be combined with other engineering plastics to form heat-resistant polymer alloys, which can be used for a long time at a working temperature of -160~180 ℃.

Injection mold process conditions:
Drying treatment: PEI has hygroscopic properties and can cause material degradation. The humidity value should be less than 0.02%. Suggested drying conditions are 150 ℃ and 4-hour drying treatment.
Melting temperature: 340~400 ℃ for ordinary materials; The reinforcement type material is 340~415 ℃.
Mold temperature: 107~175 ℃, recommended mold temperature is 140 ℃.
Injection pressure: 700~1500 bar.
Injection speed: Use the highest possible injection speed.
Machine selection;
PEI resin can be injected on most standard injection molding machines. Suggest using a reciprocating screw injection molding machine.
When determining the equipment size for injection molding specific PEI * resin components, two basic factors to consider are the total injection weight and the total projected area.

ULTRAM UF5011S PEI Application: Replacing metal manufacturing of fiber optic connectors can optimize component structure, simplify manufacturing and assembly steps, and maintain more accurate dimensions. Used in the automotive field, such as manufacturing high-temperature connectors, producing high-power car lights and indicator lights, sensors for controlling the external temperature of car cabins, and sensors for controlling air and fuel. It can also be used as a high-temperature resistant lubrication erosion resistant vacuum pump impeller, a ground glass joint (socket) for distillers operating at 180 ℃, and a reflector for non illuminated anti fog lamps.

The long-term use temperature of polyether resin is 338T and 356T (depending on the grade), and the combustion grade reaches UL94V-0 (10 mil thickness) according to the regulations of the American Insurance Company Laboratory. ）The oxygen index reaches 47, and the polyetherimide meets the FAA material standards for flame retardancy and heat release properties required for aircraft interiors. Its glass transition temperature is 419F and allows for intermittent use at 392F, resulting in short-term shifts at higher temperatures. At 356T, the tensile temperature and flexural modulus are above 41 and 2068MPa, respectively. Materials reinforced with fiberglass and carbon fiber exhibit higher strength and stiffness near the glass transition temperature.
