THERMAX

The Thermax Irreversible Temperature Recording Label is a series of temperature test labels that will permanently record the highest temperature reached by the label.

These self-adhesive labels consist of a series of temperature-sensitive elements sealed between heat-resistant substrates with transparent windows. Each element changes color distinctly as its rated temperature is exceeded. The changes are irreversible, providing a temperature history of the surface being monitored. The labels will not de-laminate when removed for reference and can be attached to an inspection report to serve as a permanent record.

The temperature-sensitive elements are phase-change indicators which use the sharply defined melting points of a series of specially purified organic chemicals to give the unique, high precision, color change effects. Each temperature element uses a different chemical compound and is made separately by applying a coating containing the chemical to a special absorptive paper substrate. When the rated temperature is exceeded, the chemical melts and is absorbed by the substrate, causing a permanent color change. Up to ten elements can be combined together on a single label.

Thermax Labels: Motorsport Applications

Thermax® Labels used on Race Brake Calipers

While the car is racing and trying to reach maximum pace, the brakes are often applied hard. The friction of the pads against the rotating discs then transfers heat to the calipers.

If the temperature reaches 250°C, the brake fluid may lose its non-compression status causing brake fade. If this occurs, the brake fluid should be replaced at the next pit stip.

The caliper is an ideal place for the Thermax® Label, as it provides a clear view of the brake fluid temperature.

Thermax® Labels used on Engine Cam Covers – Race Prepared Engines

While working at maximum performance, the top half of the engine must be kept within safe working limits to prevent damage. Water moves around the engine to cool the components. However, this can cause boiling temperatures.

When the car is at the pit-stop, Thermax® Labels can be used to record the water temperature while in motion, giving a quick reference for the mechanics. These labels can also be used on radiator and cylinder heads.

Thermax® labels used on Shock Absorbers – Competition Shock Absorbers on Rear Axle

Modified exhaust pipes, especially on turbo-charged cars, produce much hotter air that can possibly overheat the nearest shock absorber.

This can affect the vehicles handling and reduce up to one quarter of the car’s suspension stability. Placing Thermax Labels on the lower casing will give a clear indication if this is happening during a race.
