Why is PPSU more competitive than brass
Jul 06, 2022
Although PPSU is a very sophisticated raw material (it is used in the aerospace, chirurgic and optic industries) and, for that reason, an expensive material, it has two important advantages compared to brass:
Lower relative density: PPSU relative density is 6,5 times lower than that of brass so with 1 kilogramme of PPSU you can produce 6,5 more fittings than with 1 kilogramme of brass.
More efficient production process: PPSU manufacturing process is much more efficient than brass manufacturing process as it is made in one simple and automatized step with nearly no human intervention. To the contrary, brass manufacturing process has many different phases and is very labour intensive.
The consequence of these two advantages (quality of the product and more competitive price) is leading the top European companies of the plumbing and heating industry to launch ranges of PPSU fittings and to substitute the brass for PPSU made fittings.
