The case study concerns the design and development of the Dyneema® product line and specifically its application in ballistic protection. The first part is about the yarn and the second part is about the ballistics. Why is there a difference? DSM has developed the yarn for a general market, so for all the markets being it ropes, being it nets, being it cut resistance, but also ballistics. That is where it started off with. After having the basic yarn, we moved into the applications and then it was found out that specific applications require changes to be made in the yarn, but also the value chain and approach to project management.
