    1. The nominal properties reported herein are typical of the product, but do not reflect normal testing variance and therefore should not be used for specification purposes.  Values are rounded. 
    2. The physical properties were determined on compression-molded specimens that were prepared in accordance with Procedure C of ASTM D4703, Annex A1.
    3. Properties were measured on rotational molded samples with 1/8” (3.17 mm) average thickness, unless otherwise noted.  The average peak internal air temperature during molding was 400ºF.
