HT Mica Strip

Our Mica Strip heaters are a cost-effective and reliable way to provide uniform heat over a flat surface. Best suited for low to moderate temperatures, Mica Strips offer a wide variety of screw and lead termination styles.

Mica Strips feature thin construction and high quality insulation for effective heat transfer and excellent dielectric qualities.

Features & Benefits

  • Computer calculated design.
  • Quality mica electrical insulation.
  • Ribbon resistor offers broad surface contact for extended life.
  • Welded terminal attachments to resistor.
  • Heat resistant sheath material.
  • Variety of screw or lead terminations and arrangements.
  • Mounting holes available upon request.

Mica Strips are ideal for situations in which medium to low temperature strip heating is required. Typical applications include:

  • Heating rubber platens
  • Compression molding
  • Heating inks
  • Sealing bars

In addition, Mica Strips can be modified to meet the demands of virtually any special application. Our engineers can utilize a variety of alternative features and options to customize the heater to your specific needs.

Leads can be arranged on either end, or on the same side exiting the thickness or the width. Mica Strip comes standard with fiberglass leads. 10" (25.4 cm) leads standard; other lengths available.

Engineering Note
Improperly chosen lead arrangements are a major cause of application problems. Use special care in selection of leads where physical abuse and high temperatures are likely.

Simple to wire stainless steel screw terminals are available arranged at each end, on the same side arranged along the length, or on the same side arranged along the width.

Plain Leads

Jacketed for continuous service up to 482°F (250°C) with nickel standard conductors. It is recommended to use Monel® lugs.

High temperature mica tape lead wire is suitable up to 842° F (450° C) max. with nickel stranded conductors. Outer jacket is glass Teflon® finish. The use of Monel® lugs is recommended. Better Band comes standard with mica tape.

Sleeving

Fiberglass silicone rubber coated sleeving class c -1, 392° F (200° C ) service. Provides extra insulation where wire is exposed to heat, molten plastics or abrasion. Rated 1500 volts at 428° F (220° C), except 5/16" (7.9 mm) size which has no voltage rating. This size used primarily to enclose multiple insulation wires in heat and abrasion resistant covering.

Stainless Steel Braid

Stainless steel over braid is most commonly specified in applications where leads may be subjected to abrasion due to movement of the application. Lead wires may be rubbing together or passing over sharp objects.

Stainless Steel Armor

Used over leads in areas where more protection is necessary. Selected for similar applications as the stainless steel braid, in addition to applications where non-fluid contamination may come in contact with the leads. This lead protection is not as flexible as the braid.

Stainless steel square lock construction.

Convoluted Armor

This is a seamless product and can be attached to the heater so that fluids do not contaminate the leads. This system of lead protection is generally associated with the “Sealed Band” construction. Not recommended where leads are flexed in the application.

Relief Spring

This optional relief spring is welded to the band sheath. It adds protection from abrasion while keeping the leads very flexible.

Specify length, maximum length: 12" (30 cm)

Copper Elbow

Simple straight abrasion-resistant stainless steel armor or moisture-resistant armor is attached to a 90° copper elbow to accommodate applications where lead access is only possible from one side and armor exit direction is a concern.

When ordering without a swivel option, specify direction of 90° copper elbow.

Pipe Coupling/Extension Tube

These pipe couplings, welded to the heater sheath, provide a method of fastening conduit or armor to the heater which can be disconnected from the heater as required.

Standard stainless steel.

Standard Terminal Box

Designed for protection safety, snap-off cover leaves terminals easily accessible.

For heaters 1 1/2" (38.1 mm) or wider with screw terminals at one end along length on top. Also with screw terminals at one end across width, on top 2 5/8" (67.0 mm) or wider.

Terminal cover protects terminals against accidental grounding or short circuit due to spillage.
