Phenolic tubing is a resin impregnated, spiral wrapped, and heat cured tube. It is much stronger than cardboard tubing, with almost 5x the compression strength.  It is also a very good base for rockets that will require the strengthening of fiberglass, Kevlar, carbon fiber, or similar materials. For this reason, we recommend phenolic as the appropriate tubing for rockets that are 6.0, 7.5, or 11.4" in diameter, or rockets that will require strengthening for the rigors of transonic or supersonic flight. We also recommend phenolic for transonic or supersonic flights in kits of 1.1" through 2.5" diameter, as phenolic can withstand those flights without strengthening in most instances. PML Phenolic tubing is very heat resistant and is highly recommended for motor mount tubes and minimum diameter applications.

Customer Reviews (4.6 / 5 · 5 reviews)

Joseph ★★★★★

The compression strength claim is no joke—this tube took a solid drop test without a dent. The spiral wrap texture also gives paint and primer something to really bite into, which saved me prep time.

Natalie ★★★★★

Finally got this installed and the spiral-wrapped finish made for a much cleaner bond with the epoxy than plain cardboard. It handled the motor mount stress without any flex, just feels solid.

Thomas Y. ★★★★★

Swapped out the cardboard tube in my mid-power build for this and the difference is obvious the moment you squeeze it. The spiral-wrapped phenolic feels rock solid and the compression strength is no joke compared to what I was using before.
