Parker's Thermo-Chem
Thermo-Chem Firewall Rope, Tape, Sheet, Cloth, and Tubing
Providing long heatsealing life with high conformability with Thermo-Chem
Thermo-Chem™ firewall sheets, rope, tape, cloth and tubing are flexible, fire-resistant fabric products used in applications where flame and fuel resistance is required.
Their composition and construction from woven and texturized glass yarns, plain or wire-reinforced, form a non-porous, non-fraying, high tensile strength, firewall that offers long-term resistance to oils, solvents, vibration and abrasion. In addition, their flexibility enables them to readily conform to a variety of shapes.
Product Features of Thermo-Chem:
- Flame and fuel resistant
- Long-term resistance to oils, solvents, vibration and abrasion
- High tensile strength
- Flexible with high conformability
- Available in various configurations: sheet, rope, tape, cloth and tubing
- Widely used in aircraft firewalls, binding edges of metal components
- Extensively used in thermal applications for boots, bellows and expansion joints

Applications of Thermo-Chem
Thermo-Chem glass fabrics are widely used to seal openings in aircraft firewalls. These materials are also used as boots, bellows, expansion joints, bindings on the mating edges of metal parts, and in other aviation-related applications where flame and fuel resistance is required.
Advantages of Thermo-Chem
As a result of their composition and construction, Thermo-Chem glass fabrics form a non-porous, nonfraying, high tensile strength, flameproof firewall sheet that offers long-term resistance to oils, solvents, vibration and abrasion. In addition, their flexibility enables them to readily conform to a variety of shapes.
