Best Pei Film Manufacturer

About PEI Film

PEI, also known as polyetherimide, is a special engineering plastic. A transparent amber-coloured amorphous thermoplastic special engineering plastics, English name: Polyetherimide, abbreviated PEI.

The molecular structure of PEI contains both aromatic amine functional groups and ether structure, the aromatic ring and imide to give him stiff creep resistance and high temperature stability, while the ether bond makes it have thermoplastic moulding required by the smooth performance.

PEI density: 1.27g/cm³, glass transition temperature of 215 ℃, heat distortion temperature of 198-208 ℃.

The company, as a high-tech production enterprise that realises the lightweight and miniaturised application of PEI, has successfully developed PEI film, which is another high-performance special engineering plastics film that has been grandly launched after PEEK film. It is in a thin PEI film fully demonstrates the above inherent advantages and characteristics of PEI resin, fully broadens the application scenario of PEI, provides extraordinary flexibility and freedom for design engineers to carry out innovation, and also provides China's own solutions for China's high-end manufacturing.

Specific application scenarios

in the high-end field of PEI films

PEI is an excellent coating and film-forming material, which can form coatings and films suitable for the electronics industry, and can be used to manufacture microporous diaphragms with a pore size of <0.1μm and high permeability. It can also be used as high temperature adhesive and high strength fibre. Due to PEI's excellent comprehensive and balanced performance, the specific application scenarios of PEI films are mainly in the following high-end fields:

● Vibrating film materials for electroacoustic devices
● Temperature-resistant insulating materials for industrial applications (e.g. motors), membrane switches
● Base materials for 3D printing
● Bio-hybrid films for medical applications
● Film materials for professional temperature-resistant film capacitors
● High-temperature vacuum packaging film
● Solder Resist Tapes

FURUll PEI Film

FURUll as a high-tech production enterprise that realises the lightweight and miniaturised application of PEI, has successfully developed PEI film

Advantages of PEI Film

① With high and long-term heat resistance, good thermal stability, glass transition temperature of 217 ℃, long-term use of the temperature up to 180 ℃; with excellent dimensional stability, in a wide range of temperatures with in the linear coefficient of thermal expansion is low and stable, so the ambient temperature on the size of the effect is very little, in the case of higher temperatures and loads are used in the case of no deformation, creep sensitivity is low.
② Has excellent mechanical strength and modulus, outstanding electrical properties, in a wide range of temperatures (-40 ℃ -180 ℃) and frequency range can still maintain a basic constant, with a stable dielectric constant and dissipation factor.
③ It has very good infrared transmittance and high refractive index.
④ Without adding any additives, PEI has outstanding intrinsic flame retardancy, low smoke density and low heat release properties.
⑤ It has excellent resistance to radiation and chemicals, as well as unique plating capabilities.
⑥ For processing performance, PEI has low melt viscosity and high flowability, and can be moulded by conventional thermoplastic melt processing techniques and equipment, etc.
