The PTFE wire will be an important component of the wire harness solution that connects to the customer’s product, as it can withstand the high heat and aggressive environment of under hood auto and heavy transportation vehicle exposure. > Markel also provides this customer with two additional product components, both of which are used in the wire harness solution. Markel had previously been the customer’s provider of PTFE wire, but lost that business nearly ten years ago due to increased price competition from global providers.
