To enhance the cost and environmental benefits of wall-hung condensing boilers for residential use, Sabic Innovative Plastics offers high-performance Noryl, Ultem and Cycoloy resins to replace traditional metals such as copper and brass used in boiler components such as condenser housings and manifolds.

These engineering thermoplastics, developed and tested at the company’s Fluid Engineering Centre of Excellence, may enhance design freedom, extend part life, and avoid the use of heavy metals such as lead, the company says.
“Through our research and testing, we offer customers the latest material solutions for designing next-generation products that can efficiently heat homes without overheating the planet,” said Gunes Celik, Sabic Innovative Plastics’ new business development manager in Europe. 
The company has developed the new resins to provide many advantages over existing metals. For high-efficiency condensing boilers, which are growing annually by 10 per cent in Europe, Noryl PPX resin offers a better choice than stainless steel for condenser housings, it says.
As wall-hung boilers become more efficient, the temperature requirement for the housings drops, while chemical resistance becomes more important (due to condensation of exhaust fumes). With greater exposure to chemicals, metal corrodes. Noryl PPX resin provides exceptional chemical resistance for longer part life, as well as the ability to withstand the required heat from the condenser, the company says.
