sticking may be minimized by covering the heating surfaces with a
stick-resistant coating such as polytetrafluoroethylene (PTFE) or polyphe-
nylene sulfide (PPS). Copper or copper alloys are not suitable without
coating because some polyolefins react with copper.

A
Dimensions are for heater faces at the commonly used operating temperature of 500 °F (260 °C) (see AnnexA1 for dimensions for coated, aluminum heater faces at
73.4 °F (23 °C )).
B
Recommended heater faces should be manufactured close to maximum diameter for fitting heater faces and close to minimum diameter for pipe heater faces to allow
for wear and recoating.
C
Minimum dimensions have zero negative tolerance. Maximum dimensions have zero positive tolerance. The sketches and designs of the heater faces are illustrative
only. Entrance and base chamfer or radius is optional. The maximum entrance and base chamfer or radius is 0.03 in. (0.7 mm).
