Superio UT PEI Film introduction

SUPERIO UT is a high heat-resistant engineering plastic films developed with Mitsubishi Plastics’ film-forming technology using ULTEM (Polyether
-imide resin) of GE Plastics (USA).
There are two types of product, conventionally ‘E-type’, and new product ‘F-type’. F-type is superior to E-type in solvent and heat resistance under the
stress. It is a heat-resistant insulation material that lends itself to use for the applications that are required solvent resistance.
We have an assortment of SUPERIO UT that developed and commercialized for the market for customer needs such as heat resistant labels,
self-adhesive tapes.

Superio UT PEI Film Characteristics

1. Mechanical properties
－Excellent mechanical properties as an engineering plastics. (High tensile strength, crack-resistant)
2. Electrical properties
－Stable electrical properties (good low frequency characteristic and low temperature dependence)
3. Heat resistance
－ Superior Glass transition temperature among the thermoplastic resin which is 200℃ or more.
－When heated up to 210℃, change in dimension is small.
4. Chemical resistance
－Excellent chemical resistance against aliphatic hydrocarbons, acid and dilute alkali.
Especially, F-type has high chemical resistance against Polar solvent.
5. Weathering resistance
－Good ultraviolet resisting property
6. Combustion resistance

－Acquired UL-94VTM-0 (Thickness:25um～250um)
－Low smoking value (The smaller level than the smoking value of other plastics films for general use)
7. Heat moldability
－Capable of forming by heating.

Superio UT PEI Film Applications

1. Diaphragm for Speaker
Since this product has a good acoustic properties came from its specific modulus and tanδ, and also has excellent heat resistance, it is used for
portable telephones and car audio sets. Black color coated, aluminum and titanium spattering films are also available.
2. Insulating material
－Motors
－Motors for refrigerators
－Transformers
－Generators
－Wire sheathes
3. Circuit Board
－Membrane switches,
－Flat Heater
－Connectors
4. Heat resistant label and tapes
As this product has a good dimensional stability under heat and solvent, and is acid and alkali resistance, it is used for heat-resistant labels for
anode coating, electronics material and heat-resistant tape of TAB.
