Frame Profiles

Thermoplastics: a mature alternative to metal

High-alloy metals have long been regarded as the material of choice for applications in aggressive environments, such as flue gas cleaning. Thermoplastics such as polyphenylene sulphide (PPS) are a modern, high-performance solution that is in no way inferior to the metals commonly used for applications subject to high chemical, thermal and mechanical stresses. PPS is notable for its very high resistance to chemicals and heat distortion, and for its high rigidity. It thereby satisfies the highest requirements for corrosion resistance and stability.

As a material for frame systems in flue gas applications, PPS offers compelling advantages over high-alloy metal, owing in particular to its superior facility for processing and its scope for adaptation of profile and connecting elements manufactured from engineering plastics. Further processing of alloyed metal components, such as the drilling of holes for the addition of socket or threaded joints during assembly, is far from straightforward. By contrast, plastic profiles can be adapted to changing requirements without their corrosion resistance or stability being impaired.

The manufacture of both load-bearing profiles and their connecting elements from thermoplastics such as polyphenylene sulphide (PPS) enables modular frame systems to be achieved that meet the most demanding requirements for chemical and mechanical resistance, permanently and as a complete system.
