DOMO Chemicals launches PEEK solution to replace PAI
Bearing, Plate, Engine, Equipment, Machine Part
The new solution has been specially developed to replace polyamide-imides (PAI), without impacting performance.
THERMEC K is an innovative experimental product that has been developed at DOMO’s Mumbai-based laboratory in India. The solution is suitable for numerous industrial applications, including bushings and bearings, aerospace parts, pump and valve components, medical instrument parts and food processing machinery components.
Tushar Parida, Country manager India at DOMO, said: “Generally speaking, the mechanical properties of PAI are higher than those of PEEK-based parts, due to the different types of polymers the material contains. But it is more expensive too. However, through the careful formulation work of our Indian development team, we have been able to match the friction and wear performance and dry lubrication properties of PAI in a PEEK-based solution.”
In addition to offering comparable tribological properties to PAI, THERMEC K can be processed using a standard injection moulding procedure. This means that the use of complex cold injection moulding equipment followed by a lengthy steam curing process is unnecessary. THERMEC K offers a wide range of material property benefits that ranges from exceptional properties at elevated temperatures, chemical resistance, mechanical strength, strong wear and fatigue resistance, and dielectric strength.
DOMO plays a growing role in the higher performance polymers market. The extensive THERMEC product range has been developed to meet the demands of specific application requirements.
The enhanced polymers solution range features new solutions based on polyphthalamide (PPA): THERMEC N; polyphenylene sulfide (PPS): THERMEC S; and polyether ether ketone (PEEK): THERMEC K).
