Insulating Boiler Pipes

I have a small section of our boiler pipes that run under steps in a sunroom that I want to insulate. Can I use the pipe insulation material at the hardware store? Polyethylene? Rubber? Are one or both rated for that level of heat? Could not find specs labeled on either type. Thought I would find more expertise here than at the HW store.

Thanks.

The slitted, black foam piping insulation sold in hardware stores is good for 300 deg F. That will be fine for hot water heat. I'm unsure of rubber.

The black foam rubber will be fine

The black foam rubber pipe insulation is fine for heating system pipes. It comes either solid to slip over pipe while plumbing the system, or slit with adhesive tape for later installation. Be sure to buy the slitted type for pipes already in place. Slitting the solid type yourself would be be an unsatisfying experience.
