PVC vs. Polyurethane Belts: What’s the Difference?

If you’re looking to set up a new conveyor belt system, it can be difficult to know which kind of belt is best for your business. Choose the wrong belt, and you may end up with a conveyor that’s hard to clean or has carryback issues. Let’s break down the difference between two of the most popular kinds of belts: PVC and polyurethane.

Composition and Design

PVC stands for polyvinyl chloride, which is a kind of plastic. A typical PVC belt has a plastic surface with a synthetic canvas inside, which is usually made of polyester or nylon. Most PVC belts have ridges or teeth on the service side to help grip items on the belt.

Polyurethane belts, on the other hand, have a smooth polyurethane surface with tension members on the inside. A nylon fabric tooth facing is usually on the back.

Oil Resistance

Probably the most major difference between PVC and polyurethane belts is that the latter holds up much better against grease, oil, and solvents. If your new conveyor system will handle meat or fried foods, you’ll definitely want to choose either a polyurethane belt or a PVC belt with added protective coatings to help it resist all types of oil.

Temperature Resistance

Both types of belts can handle a moderate amount of heat and cold. However, polyurethane belts can handle more extreme temperatures. If you’ll be producing very hot or cold products, you may want to stay away from PVC belts. However, PVC belts work perfectly fine for most other situations.

Ease of Cleaning

Cleaning is a category where both types of belts are pretty much equal. As long as you use your belts as directed and use a cleaner approved by your belt supplier, you should have no problems keeping your belts sanitary and bacteria-free.
