High temperature resistant PEI rod

Color amber transparent dark yellow
Board name Chinese polyetherimide board English name r board is a non-crystalline plastic. It is an amorphous high-performance polymer. It is an engineering plastic made of amorphous polyetherimide and is extruded at high temperature by an extruder. The commonly used boards currently use American raw material trade names, and American companies began research and development in 2000.
The main characteristics of the board
It has the best high temperature resistance and dimensional stability, as well as chemical resistance, flame retardancy, electrical properties, high strength and high rigidity, etc. It not only has high mechanical performance, but also has excellent heat resistance and chemical stability, continuous use temperature, as well as high dimensional stability and creep strength. It has high strength, high rigidity, wear resistance and dimensional stability at high temperatures. It has inherent flame retardancy and low smoke without adding any additives, with an oxygen index of 100% and a combustion rating of 100%.
The density of the board is ~/, the glass transition temperature is, and the heat distortion temperature is ~. It can be used for a long time under ~, and the maximum allowed intermittent use temperature is. It has excellent mechanical strength, electrical insulation properties, radiation resistance, high and low temperature resistance, fatigue resistance and molding processability. Adding glass fiber, carbon fiber or other fillers can achieve the purpose of reinforcement and modification. Its unique torsional strength among thermoplastics makes it a Inexpensive alternative to small steel cutting parts.
Application fields of boards
Polyetherimide has excellent comprehensive balance properties and is effectively used in industrial sectors such as electronics, motors, and aviation. It can also be used as a metal substitute material for traditional products and cultural and daily necessities. . In the electrical and electronics industry sector, components made of polyetherimide materials have been widely used, including high-strength and dimensionally stable connectors, ordinary and micro relay housings, circuit boards, coils, flexible circuits, mirrors, high-precision dense fiber optic components. What is particularly striking is that using it to replace metal in manufacturing fiber optic connectors can optimize the component structure, simplify its manufacturing and assembly steps, and maintain more precise dimensions, thereby ensuring that the cost of the final product is reduced by approximately. Impact-resistant sheets are used in various parts of aircraft, such as portholes, nose parts, seat parts, backrests, inner wall panels, door coverings, and various items for passengers. Composite materials composed of polyetherimide and carbon fiber are already used in various structural parts of the latest helicopters. Utilizing its excellent mechanical properties, heat resistance and chemical resistance, it is used in the automotive field, such as for manufacturing high-temperature connectors, high-power car lights and indicator lights, sensors for controlling the external temperature of the car cabin, air-conditioning temperature sensors and controlling air and fuel. The sensor for the mixture temperature is the combustion temperature sensor. In addition, it can also be used as a reflector for non-illuminated anti-fog lamps at the ground glass joint socket of the evaporator in which the vacuum pump impeller is resistant to high-temperature lubricating oil erosion. Polyetherimide foam is used as thermal and sound insulation materials for transport machinery, aircraft, etc. It has excellent hydrolysis resistance, so it is used as handles, trays, clamps for medical surgical instruments, prosthetics, medical lamps, reflectors and dental appliances. In the food industry, used as product packaging and as trays for microwave ovens. It has excellent high temperature mechanical properties and wear resistance, so it can be used to manufacture valve parts for water pipeline steering valves. Due to its high strength, flexibility and heat resistance, it is an excellent coating and film-forming material. It can form coatings and films suitable for the electronics industry, and can be used to manufacture microporous separators with pore diameter < 1 and high permeability. It can also be used as high temperature resistant adhesive and high strength fiber.

Important Notes Specifications*/*/
? This amorphous thermoplastic is very sensitive to stress brittleness when in contact with polar organic solvents such as ethanol. The working environment is completely harmless to unstressed parts, but can cause stress cracking in highly stressed parts. Not only the external load generates stress, but also the internal stress generated during the mechanical processing and profile production process will have a great impact on the stress embrittlement phenomenon. Therefore using some form of heat treatment to stress-relieve machined parts will minimize the risk of stress cracking. Oil-based coolants should not be used during machine processing of these amorphous thermoplastics as they appear to increase environmental stress cracking. For these materials, the best coolants are pure water or compressed air.
? In view of the poor wear resistance of the plate and the large friction coefficient, it is not recommended to be used in situations where friction or wear resistance is required.
