Common Brand Names:
Cellidor B, Tenite Butyrate
 
General Description:  

General Description : An amorphous, transparent thermoplastic similar to cellulose acetate but more expensive and tougher with better weathering resistance and lower moisture absorption.

Applications are also similar with the addition of goggles and signs and the exclusion of graphics films.

The light control sheets available from stock can be thought of as miniature Venetian blinds encapsulated between plain CAB films.
