Murpec® [FS]

Chemical Family: Polyether Ether Ketone (PEEK)

Murpec® [FS] in comparison with other thermoplastics, Murpec® has an exceptionally low thermal expansion coefficient. This property provides optimum dimensional stability and means that dimensions do not change even if used in wet environments. Because of the high glass transition temperature, the material’s rigidity and strength are retained almost in their entirety even at high temperatures. Murpec® materials are extremely resistant to deformation and exceptionally abrasion-proof. Production based on PEEK.
