Polymer Components for Fluid Power Systems

Aztec Plastic has been combating leakage problems in poppets and spools by using torlon polyamideimide from Amoco Polymers, with its customers seeing dramatic results.

As hydraulic power systems undergo changes to handle heavier loads and provide longer service life, internal components are changing. Where steel poppets and spools were once sufficient for  most fluid power applications, new parts made of an advanced engineering polymer are delivering superior performance and service.

Fluid power systems for earth moving and agricultural equipment are changing. Operating at higher pressure gives a fluid power system the capacity to do much more work. Another advantage is that a much smaller system can do the same work that once required a larger system.

Traditional steep poppets and spools have served as a barrier to higher, more efficient operating pressures. It is important to know that steel parts will leak to some degree during normal operation, and that the leakage will increase with the number of operating cycles. Systems that use steel poppets and spools generally require frequent rebuilds.
