RA Series

Mark free by special treatment at the molecular level！

By using a special treatment on the rubber (suction cup) to improve itssurface, adhesion of foreign matters on the suction cup is greatly reduced as no particles of the suction pads will be transferred to the workpieces.

 

Note：Please note that, depending on the workpieces, usage conditions and the environment, the effectiveness may vary and that, in certain cases, the use of these suction cups may have no effect.

 

Optimum for conveying glass sheets and other workpieces that need to be free from marks.

 

For various shapes cups.

If this suction cup material is used for fluorine rubber and conductive fluorine rubber, suction cups of any series can be used（exclude a few model).

Symbol	Material	Hardness (A/s)	Ambient temperature (๐C)	Color	Volume resistivityNote1.2
F-RA	Mark free fluorine rubber	70	-10～230	Black with white dot	–
FE-RA	Mark free conductive fluorine rubber	70	0～200	Black	104～107 Ω・cm

Note1) Volume resistivity shows conductivity, resistance value is per cm³.
Note2) It is the measured value of in our designated test piece.

 

Feature

Using our own treatment method the rubber surface is given improved quality,reducing suction marks to the limits.Each series correspondence is possible.

Application:Optimal for work pieces that are sensitive to marks,such as semiconductor chips and glass products.
Lineup:The suction-pad material is used only with fluorine rubber.
