Metal belts have better thermal conductivity properties than plastic belts.

Plastic belts have a greater drive surface contact area than metal, making them a better choice for lower tension systems.

Since plastic belts are modular in design, maintenance and repairs made in the field are easier and quicker than metal belts. No special tools, grinding or welding is necessary.

The least expensive metal belt is less expensive than the least expensive plastic belt. Metal belts have an advantage overall because they are not petroleum based.
