  • Project management at DuPont
    Partial Transcript: "Well, initially it was a one man band kind of thing..." "My line of responsibility was technical..."
    Synopsis: Merriman talks about project management at DuPont. He says that there wasn't really a manager on the product side. He talks about the influence of technical managers and how they defended his projects. He says that his job at the time was to figure out how to use Kevlar to replace asbestos in any project, not just brakes.
    Keywords: asbestos; development; Kevlar; management; marketing
  • Measuring Kevlar fibers in the air
    Partial Transcript: "A lot of those places we would go into and put air monitoring devices on the workers..." "It tends to be its own filter... while you may see a lot of dust, very little of it is Kevlar..."
    Synopsis: Merriman continues his discussion of Kevlar in the brake manufacturing process. He details how DuPont measured the amount of Kevlar fibers inhaled by factory workers. He says that Kevlar is non-toxic and that it serves as its own filter, meaning that not very many Kevlar particles are in the dust at a factory. He says that good air handling practices will keep Kevlar particles low. He says that their goal was to make Kevlar safe to work with and to make sure it would not be a health hazard like asbestos.
    Keywords: air; asbestos; brakes; breathing; hazards; Kevlar; manufacturing
  • Later career in the Kevlar and Nomex divisions
    Partial Transcript: "I was always looking for the end uses of...Kevlar pulp..." "I was half working for Nomex and half working for Kevlar in the health safety and environmental area..."
    Synopsis: Merriman talks about the rest of his career at DuPont. He says that his time was spent between Kevlar and Nomex, developing new uses for Kevlar pulp and Nomex. He talks about creating combined Kevlar and Nomex materials. He talks about how a large portion of his career was spent traveling to factories around the world and teaching factory operators how to safely handle Kevlar and Nomex. In addition to teaching factory operators about health and safety Merriman taught them how to properly mix Kevlar and Nomex fibers.

  • Processing Nomex
    Partial Transcript: "Well, Nomex, while it has crystal orientation it doesn't peel into fibrils the way Kevlar does..."
    Synopsis: Merriman talks about how DuPont processes Nomex and Kevlar paper. He focuses on the manufacture of Nomex paper and explains the uses of Nomex paper. He says that Nomex paper is made and cut like wood pulp paper. He explains that Kevlar cutting is more difficult to do, then describes the process. He talks about how cutting the fibers into short lengths made what was a waste material into a usable material.
    Keywords: Kevlar; Kevlar paper; materials processing; Nomex; Nomex paper; Nomex pulp
  • Kevlar fiber and pulps and newer fibers
    Partial Transcript: "The thing that came out of that is now whenever anybody is thinking about a fiber, they think about a pulp..." "Is there enough of a prospect that this will be used as a pulp that we need to... assure ourselves that its a safe product..."
    Synopsis: Merriman talks about the future of fiber industries and how Kevlar set a precedent of using fibers in pulp form as well. He talks about attempts to replace Kevlar fiber as a material by some of companies that he worked with due to cost. He says that despite facing these objections on a regular basis he enjoyed his work selling Kevlar.
    Keywords: fibers; Kevlar; Kevlar pulp; pulps
  • Challenges selling Kevlar
    Partial Transcript: "From time to time there would be resistance because of the price, they'd see price per pound and it would be atrocious compared with all the other materials they were buying per pound."
    Synopsis: Merriman talks about some of the challenges of selling Kevlar. He says that potential customers often balked at the price per pound. He says that the low compressive strength of Kevlar made it a hard sell to the aircraft and aerospace industries, but that changed when they learned how to combine it with other materials.

  • The Spruance Facility
    Partial Transcript: "Spruance was always the manufacturing sight for Kevlar, but it took quite a while for it to become the manufacturing site for Kevlar pulp."
    Synopsis: Merriman explains how the Spruance plant in Richmond, Virginia became the production site for Kevlar, Kevlar pulp, and Nomex. He talks about how the Spruance plant became DuPont's site for fiber research, development, and sales. He says that having labs and manufacturing on the same site make research and development especially easy. He briefly talks about the history of the Spruance facility, which was first built in 1929. He talks about the location of the Spruance plant in the city of Richmond, Virginia.

  • DuPont work culture
    Partial Transcript: "I have three degrees in metallurgical engineering and I think I practiced metallurgical engineering for about twenty minutes or so."
    Synopsis: Merriman talks about the work culture at DuPont. He explains what he meant earlier when he said that everyone was a generalist. He says that if someone was determined to be a specialist they could, but the natural evolution of jobs at DuPont, combined with personal curiosity lead to generalization. He says that generalization helped him on the job and that he enjoyed it.

  • Changes to DuPont's business and research interests
    Partial Transcript: "I think if you were into a more theoretical area that didn't have an immediate market use... you were more likely to have trouble justifying your job."
    Synopsis: Merriman talks about change over time to DuPont's business and research goals. He says that overtime DuPont, and many other companies switched from having an open approach toward research and development to being more focused on what could be sold. He characterizes his time there as the golden age of research and development at DuPont.

  • Dupont's experiments in metallurgy and other types of materials
    Partial Transcript: "When I was thinking of becoming a graduate metallurgist I had in mind going to the Baltimore Metal Center."
    Synopsis: Merriman briefly discusses some of the metals businesses at DuPont and elsewhere with a focus on making and selling titanium dioxide. He discusses marketing products when your own are virtually identical to the your competitor's products. He talks about how DuPont paid for some of the advertising costs of their customers in order to promote materials that they developed.

  • The health, safety, and environmental regime at DuPont
    Partial Transcript: "When Jefferson became CEO of DuPont and Chairman, his very fist speech was about how DuPont needed to be a leader in product stewardship... he said every product needs a product steward..." "... it's in our own best interests from a business standpoint to be socially conscious of the environmental and health aspects of our products..."
    Synopsis: Merriman talks about health, safety and environmental concerns at DuPont. He talks about the creation of the product steward job at DuPont. He describes how he became the product steward of Kevlar and went from managing the problem of inhaled Kevlar fibers to the whole health, safety, and environmental impact of Kevlar.He says that it made good business sense and that product stewardship became a part of new product development.
