Many gaskets consist of synthetic fiber held together by what?

1. Water

2. Binding Material

3. Chemical Adhesives

4. Natural Fibers

The correct answer is: Binding Material

Many gaskets are made from synthetic fibers that are consolidated through a binding material. This binding material serves to hold the synthetic fibers together, forming a cohesive and effective sealing product. It is crucial for the gasket's functionality, as it must maintain integrity under various temperatures and pressures typically encountered in mechanical applications. The binding material enhances the gasket's durability, resilience, and overall performance by allowing it to withstand the rigors of its operational environment, such as exposure to fluids and gases. It ensures that the fibers do not separate or degrade over time, which would compromise the gasket’s sealing capabilities. In contrast, the other options do not fulfill the same role. Water cannot provide the necessary structural integrity needed in gasket formation, while chemical adhesives, although potentially used in some contexts, do not represent the primary structural component used in most synthetic fiber gaskets. Natural fibers themselves, while they may sometimes be used in gaskets, do not apply here as the question specifically targets synthetic fibers. Thus, the binding material is essential in creating effective gaskets from synthetic fiber.
