Questions about this item

Will the NBR/PVC elastomeric material degrade and need replacement after long exposure to high temperatures?

The insulation is rated for continuous use up to 220 Degrees F, so it will not require replacement due to heat degradation within that range.

What is the maximum continuous operating temperature before the insulation loses effectiveness?

The upper limit of the temperature range is 220 Degrees F, which is the point where sustained performance cannot be guaranteed.

Does the black NBR/PVC insulation emit any noticeable odour or off-gassing when running at high temperatures all day?

The material carries a California Proposition 65 warning for a chemical known to cause reproductive harm, but no odour or off-gassing data is provided for high-temperature operation.
