Pei Ultem Cnc Milling Machining Parts

Polyetherimide - PEI is an amorphous, amber to clear thermoplastic with properties similar to the related plastic PEEK. Compared to PEEK, PEI is cheaper, but has lower impact strength and service temperature. Polyetherimide PEI is sensitive to certain chemicals, has average impact resistance, has poorer flow than common engineering plastics, and requires molding.

Plastic instead of steel, to provide customers with the most suitable lightweight customized solutions, according to the specific performance of PEI, product structure, product quantity, product color, design a suitable customized solution, its mold processing time of 25-30 working days, samples for the mold is completed within 2 days after the completion of the shipment period of 7-15 days.

PEI is the common name for polyetherimide, is one of the world's most common engineering plastics, with excellent strength, toughness and abrasion resistance, but also can be easily processed, can be used as a variety of machine parts, such as electronics, electrical machinery and aviation industry or as a substitute for traditional products and cultural and living supplies of metal materials. That the use of PEI special engineering plastics in fact what advantages can actually replace the metal, but also than the metal has a unique advantage of performance? Just let Zhenghao take you to understand it, PEI in the end as the performance of processed parts with what advantages and disadvantages?

First, the performance of machining polyetherimide (PEI)

Polyetherimide (PEI) with its high and long-term heat resistance, good thermal stability (long-term use temperature of up to 170 ° C), because of excellent mechanical strength and modulus, outstanding electrical properties and known in a wide range of temperatures (-40 ° C ~ 150 ° C) and frequency range can still maintain a basic constant. In addition, PEI materials can be used without any additives, PEI has outstanding intrinsic flame retardancy, low smoke density and low heat release properties.

Polyetherimide (PEI) is commonly produced: for the manufacture of fiber optic connectors to optimize the structure of the component, simplify its manufacturing and assembly steps, maintaining more accurate dimensions; can also be used in the automotive field, such as for the manufacture of high-temperature connectors, high-power lamps and lights, sensors to control the temperature of the outside of the automotive cabin and sensors to control the temperature of the air and fuel mixtures. The excellent properties make it an excellent candidate as a metal replacement.

Second, the advantages of polyetherimide (PEI):

1, high mechanical strength, good toughness, high tensile and compressive strength.

Due to its high strength, flexibility and heat resistance, PEI is an excellent coating and film-forming material that can form coatings and films suitable for the electronics industry and can be used to create apertures.

2. Heat resistance

Can be used for a long time at 160~180°C, limited oxygen index greater than 4.7, low emission of

PEI has stable dielectric constant and dielectric loss and high dielectric strength in a wide range of frequencies and temperatures.

3、Hydrolysis resistance

PEI hydrolysis resistance is good, soaked in boiling water for 10,000 hours after the tensile strength to maintain more than 85%, at a temperature of 270F, can withstand high-temperature steam repeatedly sterilized steam heat pressure cycle 2000 times after the tensile degree of unchanged. It is also able to withstand inorganic acids and short-term resistance to strong bases.

4, self-extinguishing, odorless, non-toxic, chemical resistance, creep resistance properties.

5, excellent electrical properties.

In a wide range of environmental conditions can also maintain good electrical insulation stability, coupled with thermal and mechanical properties, can make PEI resin become the ideal material choice for demanding electronic and electrical applications.

6, light weight, outstanding ductility, easy to mold.

PEI both high strength and high modulus characteristics, but also has outstanding ductility. Its stretch can be freely combined with a variety of easy-to-assemble buckle fit design. Even with 10% glass fiber reinforcement, PEI maintains its good ductility at temperatures ranging from below freezing to 200°C. The fast flow rate makes injection molding easy and fast, with short cycle times and high productivity.

Third, polyetherimide (PEI) applications

PEI material is an engineering thermoplastic, easy to process, can be used as a variety of mechanical end parts. Widely used in a variety of applications serving electrical engineering parts, food industry parts, aircraft construction parts and many injection molded parts for vehicles and machinery. Processed parts such as ground glass fittings for stills operated at 180°C.
