NP320 (NEMA L) is used where better machining is needed compared to that offered by canvas grades. This product consists of a fine-weave linen fabric and general-purpose phenolic resin. Besides easy machining, NP320 operates with less noise than metal. In addition, this physical material is not as abrasive as fiberglass alternatives when used in wear applications. NP320 can be used in explosion-proof environments. It is suitable for smaller and more intricate shapes than those made with NP310, and is commonly used to make gears, pulleys, rollers, and guides.
