Mark I do not know of other types but I would think the tape version is better then a paste which might not do full coverage or dry correctly.

There are other brands that use teflon and function over a wider heat range and pressures such as :

Multi-purpose thread sealant for use on metals including steel, stainless steel, brass, copper, aluminum, and on plastics including PVC, CPVC and ABS.

• Leak-free joints can be tested and put into service at once.
• MEGALOC wipes clean from hands and tools with a dry rag, is odor-free, grit-free and will not separate or settle.
• MEGALOC Multi-Purpose Thread Sealant does not harden, crack or become brittle; joints can be disassembled without damage to pipe, fittings or threads years after the joint was made.

MEGALOC is applied easily with a natural bristle brush even at temperatures as low as -25°F, and performs over a temperature range of -50°F to +400°F.

It provides leak-proof hydraulic resistance to 12,000 psi and withstands gas pressure up to 2,600 psi.
MEGALOC is non-hazardous and non-flammable. It contains no lead, heavy metals or volatile solvents.

Multi-Purpose Thread Sealant is commomly known as pipe dope or pipe joint compound. Hercules Chemical Company's Multi-Purpose Thread Sealant is a superior product for this type of application.
