NP320U is a utility grade made of low-cost materials. For better machining than that offered by canvas grades, this product consists of a fine-weave linen fabric and general-purpose phenolic resin. Besides easy machining, NP320U operates with less noise than metal. NP320U can be used in explosion-proof environments, and is suitable for smaller and more intricate shapes than those made with NP310, and is commonly used to make gears, pulleys, rollers, and guides.
