L. K. Berry to R. D. Batson on Plastibest 20 Fiber Sold to Raybestos-Manhattan (1981)

A one-page Johns-Manville internal memo of September 30, 1981, from L. K. Berry to R. D. Batson, passing on what former J-M salesman Steve Kuhn said about Plastibest 20, "a long, Grade 4, specialty fiber with a high surface area." Raybestos-Manhattan's plant at North Charleston, South Carolina, used it to make molded rubber parts and molding compounds for the aerospace industry. The memo adds that the plant mainly made textiles, and that J-M was "a poor 'fifth'" as its fiber supplier because R-M used a "wet process" that J-M's fiber did not suit.
