TECHNICAL DATA
Physical properties:
The silver halide emulsion type is coated on a blue polyester PET base.
The film provides excellent dimensional stability, great tear resistance; does not feature an anti-static/anti-scratch layer, therefore additional care must be taken when handling this film.

Processing:
The experimental no.50 film can be processed manually in reel/spiral/hanger tanks or flat bottom dishes/trays. This film is highly robust and can handle less than ideal processing conditions, however nitrile/latex/vynil gloves must be used when handling this film. It will not contaminate the processing chemistry if pre-washed. This film can be developed by inspection under red safelight, but a minimum of 1.2 meters should be maintained from the lightsource to avoid fogging. When processed manually, it is recommended to agitate the film for 10 seconds each 30 seconds of development. The development time must be decreased/increased by 10%. each stop of pull/push processing this film.
Spectral sensitivity:
Blue(sensitive)/Green(highly sensitive)
