National Vulcanized Fiber

NVF Company, formerly known as National Vulcanized Fiber, is a private company based in Yorklyn, Delaware. One of its original products, a sheet-like material called Forbon, is commonly used on guitar pickups. NVF also makes a product called Yorkite, another vulcanized fibre, that has wood grain printed directly on the material.

The company currently generates an estimated $42.2 million in sales and has about 550 employees.

The facility at Yorklyn DE was visited on May 31, 2015. The buildings are essentially empty and the roof of one building has collapsed on its own from apparent neglect. The entire site is in the process of being demolished in preparation for redevelopment. It is apparent that this facility had been abandoned or non-functional for a period of years, based upon the level of decay I observed. Many of the concrete floors had moss growing on them - a clue to the neglect this site has witnessed. (Subjective information, needs editing)
