Murpec® Black, produced on the basis of PEEK (polyetheretherketone), has an extremely low coefficient of thermal expansion compared with other thermoplastics. This property results in optimal dimensional stability, which does not lead to dimensional changes even in wet environments. Thanks to the high glass transition temperature, rigidity and strength are almost entirely retained even at high temperatures.

Murpec® materials work with good dimensional stability and are extremely abrasion-resistant.
