The material from which a timing belt is made is one of the most critical aspects to consider. Common materials include rubber, polyurethane, and reinforced materials that include fiberglass or aramid. Rubber belts are widely used due to their good flexibility and durability. Polyurethane belts, while typically more expensive, offer superior noise reduction and wear resistance. The selection of material should align with the application's operating temperature, load conditions, and environmental factors.

PK belts are a type of serpentine belt used primarily for driving multiple accessories in vehicles. They are characterized by their unique design that features several grooves running along the length of the belt. This design enhances their grip and reduces slippage, making them a preferable choice for many modern engines.
