It has a pressure sensitive adhesive. This is different that typical electrical tape.
It is self-extinguishing (in under 2 seconds).
When unwound from the roll, will have no tendancy to curl.
Adhesive won't transfer to the adjacent layer when unwound at 24ft./min.
Various adhesion requirements to PVC and polyethelene.
Some of the testing certification requirements include such things as:
Oven Age: Hang 153mm (6") length of tape in circulating oven at 130 degrees C (266 degrees F) for 24 hours. Tape shall not melt or exhibit any adverse effects.
These are just a few of the items outlined in the specs this product must meet.
Although I've not yet seen this product, it should also have a more matte finish than electrical tape. This is probably only important to the REALLY anal guys like me

This particular product isn't what they classify as a "High Temp" item. The distributor does tell me though that it is what most of their customers use. I specifically asked about this because of some of the wiring I've put in the engine compartment and will likely re-wrap. As long as this isn't extremely close to high heat producing components it should be fine.
Another point for the other members who may not realize is that the wire insulation for conductors in the engine compartment is not the same as the rest of the body. Care should always be used in selection of wire and routing for this reason. GM'* wire selection is much different for these applciations and the insulation is designed to withstand much higher temps. Usually temperature ratings are broken down into four ranges (T1 - T4) depending on location in the vehicle. Wire, wrap, loom, connectors etc. are all selected based on these criteria.
