Thermo-Flex Heat Shield
NOTE: Only available in Silver or Black
Thermo-Flex is a composite heat shield made from a combination of aluminum, silica, and stainless steel. This strong, lightweight material can be bent and flexed for use in just about any application.
The abrasion-resistant material provides thermal insulation to hoses and wiring and can withstand temperatures up to 750°F.
This versatile product can be slit for use with wire looms or covering hoses without disconnecting the ends. Thermo-Flex is available in two different colors (silver or black) so you can customize your application. It is also available in lengths of 3 or 10 feet for your convenience.

III. Personal Protective Equipment
|Appropriate personal protective equipment is required when melting, casting, machining, forging, or otherwise processing, The nature of the processing activity will determine what form of equipment is necessary, i.e. glasses, respirator, protective clothing, and ear protection.|
IV. Emergency Medical Procedures
|For skin contact, remove particles by thoroughly washing with soap and water.|
|For eye contact, flush with water for at least 15 minutes. Get medical attention if irritation persists.|
|For inhalation, remove from exposure. Get medical attention if experiencing breathing difficulty.|
V. Health / Safety Information
|Health||Inhalation||Not likely unless material machined, welded, or re-melted. Exposure to zinc oxide fume can result in "zinc chills" (metal fume fever). The temporary symptoms can include fever, chills, nausea, vomiting, and muscular pain. Recovery is usually complete in 24 to 48 hours. Overexposure to copper fume can cause upper respiratory tract irritation.|
|Eyes||May irritate eyes when welding or plasma cutting. See #7, Additional Information|
|Waste Disposal Methods|
|Used or unused product should be tested to determine hazard status and disposal requirements under federal, state, or local laws and regulations
Disposer must comply with Federal, State, and Local disposal or discharge laws.
VII. Additional Information
- Halogen acids and sodium hydroxide in contact with aluminum may generate explosive mixtures with hydrogen
- Finely divided aluminum will form explosive mixtures in air. It will also form explosive mixtures in air in the presence of bromates, iodates, or ammonium nitrate.
- When re-melting aluminum scrap, entrapped molecule or the presence of strong oxidizers such as ammonium nitrate could cause and explosion. This applies to the collection of moisture in saw cavities as well. Moisture must be driven off prior to re-melting.
- Do not touch cast aluminum metal or heated aluminum product without knowing metal temperature. Aluminum experiences no color change during heating. If hot metal is touched, burns can result.
- Aluminum powder must be packaged and shipped as a Flammable Solid, UN1395.
- Hard alloy ingots in the 2000 and 7000 series must be stress-relieved to prevent explosion (or violent cracking) when sawed.
- The welding of aluminum alloys may generate carbon monoxide, carbon dioxide, ozone, nitrogen oxides, infra-red radiation, and ultra-violet radiation, in addition to metal fume.
- Some aluminum scrap may be contaminated with oil at levels greater than 1%. Melting of aluminum scrap may generate ail vapors which are irritating to the eyes and upper respiratory tract. Prolonged or repeated skin contact with oil may cause skin irritation.
- Vapor degrease must be properly maintained to limit the accumulation of aluminum fumes. The accumulation of aluminum fumes could result in a potential degrease fire or explosion.
