width material should be used for guide tapes. Guide tapes for ironing machinery are primarily
available in 3 versions of 2 materials – Polyester and Nomex. Nomex is a Dupont trade name for a
type of Aramid fiber with a maximum service temperature of 220
o C, perfect for high temperature
ironing. Polyester (Polyethylene terephthalate) is a very common material, also used in poly-
cotton sheets and other flat goods. Polyester typically softens at 338
o F (170 o C) and should not be
used at temperatures much above this.
• Polyester – good for steam heated ironers.
• Polyester – Aramid Blend - Good for steam and thermal fluid ironers up to about 380 o F
(193 o C).
• Nomex (Aramid) - This is the preferred material for all high speed high temperature ironers,
particularly for Thermal fluid heated ironers operating in excess of 380 o F (193 o C).
