Are TPEE membranes and PES membranes the same product?
In the market, polyester membranes are often referred to as PES. However, from a polymer materials standpoint, PES also stands for polyethersulfone, which is a completely different material. In some regions, TPEE membranes are also commonly labelled as PES membranes, which can easily lead to confusion. To avoid this ambiguity, the polyester membrane developed by Nam Liong is clearly identified as TPEE (thermoplastic polyester elastomer). The key characteristics and differences between TPEE and PES are summarised in the comparison table below.
