NOTES:

(a) Typical values; should not be used for specification purposes.

(b) Values shown are for 0.250" thickness. Some values will change with thickness or pigmentation.

(c) Difference in length and width, as measured at room temperature, before and after heating above 300°F.

(d) It is recommended that temperatures not exceed 180°F for continuous service, or 200°F for short intermittent use.
