DuPont™ Vespel® - CR Family

Luckily, being prepared simply means thinking Vespel® CR when you’re designing for a tough chemical environment. Plus, CR can provide ultra-high purity for semiconductor applications, high-creep resistance for seals, even easy machinability for tight-tolerance parts like ball valve seats.

 
CR-6100

A DuPont™ Teflon® PFA body, reinforced with high-tensile-strength carbon fiber—CR-6100 offers excellent chemical resistance while exhibiting superior resistance to creep—even up to 550°F! It also provides excellent wear resistance and easy machinability for tight-tolerance applications. Add in a CTE lower than steel in the x-y plane (due to planar carbon-fiber reinforcement), and you have an ideal material for a variety of applications.

CR-6200

Has the same resistance to creep and chemicals as CR-6100, but with a more random orientation of its fiber. Consequently, CR-6200 doesn’t exhibit the degree of x-y property orientation provided by CR-6100, but offers a balance of properties in the z and x-y directions instead.
