Yes, propane (or methane) plus oxygen.
Heat shrink tubing was invented in the 1950s, in the later years, by Raychem Corporation. The head engineer founder was Paul Cook who used radiation chemistry to invent heat shrink tubing.
Pyrex is anothe anme fore borosilicate. They are names for glass which are heat resistance and are used in laboratories.
Heat shrink tubing provides a state of the art method for the application of a tights, protective covering to items that will be subjected to the extrems of heat, corrsion.
Glasswares, except Borosilicate galsswares and wax items can be good conductors of heat usually found in kitchen.
Yes you can provided that the tubing has is tested for high heat.
IT probably would but you would have to make direct contact which might cause the heat-shrink to shrink unevenly or get flattened. It is usually better to blow hot air at it while you rotate it. A good hair dryer might work equally well. ------ Neither a hair dryer, nor a clothes dryer will work for shrinking most conventional heat shrink tubing. The most common types: PVC and Polyolefin require temperatures of greater than 100C (the boiling point of water). A clothes iron will; however you'll melt the tubing with direct contact, and it will mess up your iron. If you don't own a heat gun, you'll be fine using a cigarette lighter.

There is a lot of differences between PVC and Fiberglass. Fiberglass is going to be stronger and PVC is the plastic tubing that you find in local home repair stores. PVC tubing is cheaper than fiberglass. Fiberglass tubing is lighter in weight. PVC tubing can be bent when heat is applied, but fiberglass tubing is fixed and will break, not bend.
The website Heat Shrink offers heat shrink tubing. The company cuts to specifications as well as offering the service to print logos onto the tubing. The website itself seems fairly straightforward to navigate.
