Friction materials paper
Wet friction materials paper is a specific type of paper-based friction material that is designed for use in wet environments. Wet friction materials paper is commonly used in wet clutch and brake systems, such as those found in automatic transmissions, power take-off units, and industrial machinery.
The key feature of wet friction materials paper is its ability to maintain stable friction and wear performance in the presence of oil or other lubricants. This is achieved through a specialized manufacturing process that involves impregnating the paper with a high-performance resin system that is designed to resist degradation in the presence of oil or other fluids.
