09   Inconel wire stocking 1800°F/982°C

Ideal for

  • Temperatures up to 1800°F/982°C
  • extreme abrasion resistance

10     Aluminized Fiberglass Cloth

Ideal for

  • Temperatures up to 500° F/260° C
  • reflects radiant heat

11   Fiberglass cloth or tape 1000°F/538°C

Ideal for

  • Standard seal for ovens and doors is useful in many applications.
  • Good wear life,
  • Chemical resistance
  • Heat resistance

12   Fiberglass cloth or tape with Teflon® -100°F (-73°C) to 500°F (216°C)

Ideal for

  • Low temperature applications stable to -73°C and high temp applications <500°F
  • Applications where silicone cannot be used.

13   Silica cloth 1800°F/982°C

  • Similar characteristics to fiberglass but with higher temp ratings (<1800°F/982°C).

14   Silicone-coated fiberglass cloth -150°F (-101°C) to 500°F (216°C)

  • Impervious to air, water, many chemicals,
  • Good in cold environments and UV resistant.
  • Versatile material for many applications

15   Kevlar® cloth or tape -320°F (-196°C) to 500°F (216°C)

  • Used where high abrasion resistance is required such as
    • door sweep seals or
    • seals exposed to lots of axial movement.

22   Fiberglass cloth with Viton® 0°F (32°C) to 500°F (260°C)

  • A unique material commonly used in chemical applications where PTFE or silicone are not compatible.

23   Padmaster Vermiculite-coated fiberglass cloth 1200°F/649°C

  • Upgraded” fiberglass. The vermiculite coating increases abrasion.
  • temperature resistance

25   Teflon® Coated Fiberglass film (crease and tear resistant) -450°F (-267°C) to 500°F (216°C)

  • Similar to our 12 series but in a film.
  • This material is slick and allows water, materials, etc. to slide and wick easily.

29   Basalt woven cloth 1200°F/649°C

  • a more cost effective and environmentally friendly alternative to fiberglass and vermiculite treated fiberglass.

GT11[M]Core Material call out

C     304 Stainless steel hollow 1200°F / 649°C

  • most easily compressive
  • most resilient core material.
  • excels under light compression.
  • Excels where there is a need to conform to largely uneven surfaces.

D     Inconel 600 wire mesh 1800°F / 982°C

  • This mesh seal compresses well and is resilient.
  • resistant to many chemicals and
  • excels in ultra-high temp applications.

G     Galvanized Steel Mesh 800°F / 426°C

  • cost effective alternative to our 304SS solid mesh.
  • resists certain chemicals that 304SS does not.

L      Ceramic rope 2000°F / 1093°C

  • A cost effective ultra-high temp core material solution.
  • moderate compression and little resistance

M   Fiberglass rope 1000°F / 538°C 

  • A cost effective ultra-high temp core material solution.
  • moderate compression and little resistance

R     Silicone Sponge 500°F / 260°C

  • easily compressible and highly resilient
  • pairs well with our 14 series silicone cover material in low temp applications

S      304 Stainless steel solid mesh 1200°F / 649°C)
