Murpec® and Murpec® SP are especially suitable for applications where, under long-term static loads and high temperatures, no permanent deformations are permissible.
A modified version of the basic material, Murpec® SP offers significantly improved wear resistance, together with excellent slide properties as well as good mechanical qualities. Both Murpec® and Murpec® SP also show high chemical resistance.
Exceptional fatigue resistance
Murpec® and Murpec® SP offer high fatigue resistance, leading to long life under cyclic loads.
High chemical resistance
Their good chemical resistance allows direct contact with many substances without surface protection or high-alloy metals. They are also extremely resistant to hydrolysis and superheated steam.
High temperature resistance
Even at high temperatures, their electrical resistance values, rigidity and strength remain virtually constant. In long-term applications, especially under constant load and subject to high temperatures, they show reliable dimensional stability.
Coefficient of linear expansion
Compared with other thermoplastics, Murpec® and Murpec® SP have a very low thermal expansion coefficient (Murpec® SP's is similar to that of aluminium). That is also the reason for their optimal dimensional stability which shows no deformation even in wet operating conditions, making costly designs for plastic-metal combinations in high-temperature environments unnecessary.
Contact with food
Murpec® is approved for direct contact with food (EU directives and FDA) and is physiologically safe.
Murpec® SP is not approved for direct contact with food but is physiologically safe.
