C.A.B. is a highly impact-resistant plastic used for thermoforming a variety of OEM products for various applications. It qualifies as a Type I, Grade I material under the requirements of Standard Specification for Cellulose Acetate Butyrate Film and Sheeting for Fabricating and Forming (ASTM Designation:D2411-69)

Combining long-term weather resistance with clarity and ease of forming at a wide range of temperatures, C.A.B. Sheet is adaptable to most conventional methods of heating and forming. It will form satisfactorily at temperatures ranging from about 240° to about 280°F. It heats and cools considerably faster than most other plastic sheet used for forming outdoor components. Uniform parts are obtained consistently because of strict control of sheet thickness.

The ease with which C.A.B. Sheet forms after being heated makes possible the production of deep drawn parts using male mold and vacuum pressure alone, without the necessity for matching dies or other fixtures. Strong, rigid parts, with minimal thinning of the sheet in the areas of greatest stretching, are produced by the use of appropriate draft use on the mold. The proper draft will depend on both the depth of draw and the drawdown ratio for each part.
