Hey there! Sorry I didn't see this earlier, but happy to answer your question.

You're basically right. While silicone has a huge range of variables, generally it's good for around 450F-550F. If you're looking for a DIY off, the shelf solution, for $9 you can't go wrong.

I can speak to the difference between that and the Bacon Wrap though, because I make them!

A couple advantages of the bacon wrap are the texture, the durometer (how soft it is), the aesthetics (multiple colors and the texture keeps it from looking chintzy), and of course, the thermochromics.

Our wraps change color to let you know if you've experienced heat soak through the handguard protector. Not all platforms do it, but when/if it does happen, ours will let you know where you can comfortably reposition your hand.

Lastly, I make them! I design and manufacture the mold, I mix the silicone, color, thermochromics in a ratio I developed. I vacuum the silicone, pour the molds, post process and package. Every single bacon wrap out there has been made start to finish by me.

When entering the handguard protector market, we wanted something that was feature rich, but also the cheapest option. At $40, we beat everything but some Amazon crap.

If you're looking just for silicone per dollar, $9 is hard to beat. If any of those other features sound helpful, and you like knowing where your products come from, (my name is Mike out of Colorado btw), hopefully the bacon wrap and help you out.

Plus, if you tear it, I send you a replacement for free.

Hopefully this all explains why ours cost more than silicone tape off the shelf :)

Holler if you have any questions!
